1.1 Deep groove ball bearings
Structure of deep groove ball bearing basically includes inner ring, outer ring, roller elements and cages. Seal
rings and dust shields are designed to prevent foreign matters like dust or oils from entering. The main purpose
of lubricant used is to achieve the reduction of friction and damage of roller elements.

In daily operations, cage will be subjected not only to mechanical action from friction, tension and inertial force,
but to chemical reaction from lubricants, additives, solvents or coolants. Therefore, design and materials of
cage are very important for its performance and the reliability of bearing in usage.
CBB.F&D offers the following kinds of cage for deep groove ball bearings:
Rivet type cage Crank jaw type cage Cage with synthetic resin
material
It is a kind of cage made by
strip steels in high precision,
turned into spherical pockets
through profiling and fixed
with rivets, usually applied to

groove ball bearings.
It is a kind of cage made by
strip steels in high precision,
turned into spherical pockets
through profiling and caulked
by crank jaw and two pairs of
retainers, usually used for
miniature deep groove ball
bearings.
Synthetic resin cage is made
by combination of several
materials, including nylon
PA66 with glass fiber. It has
self-lubricating and low noise
features, usually used for
bearings with extremely low
noise.

Inner ring structure
CBB.F&D bearings have the following inner ring structures:
V-groove structure L-groove structure Flat top structure
Dust shield and seal ring
Sealing performance plays an important role in the cleanliness of lubricant and bearing life. Intrusion of foreign
matters and leakage of lubricant must be prohibited for internal sealing structure of bearing. In case that bearing
external is unable to be sealed, bearings with sealing structure will be generally applied.

2. Materials of Bearings
2.1 Materials for bearing ring and roller body
2.2 Material of cages
21 Materials for bearing rings and parts largely determine the bearing's performance and life. CBB.F&D puts more
efforts to select materials for bearing rings and part suppliers in a rigorous manner. Materials and components
of bearing rings for CBB.F&D bearings are provided by the world's top suppliers special for serving bearing
manufacturers, fundamentally solving the issue that our bearings lag behind imported bearings in terms of
materials for a long time. CBB.F&D boasts a set of strict and polished incoming goods inspection system.
Before being put into storage, every batch of steels and parts is under systemic inspection, including analysis of
material composition, metallographic analysis, accuracy check, assembly test, etc.
Bearing ring and roller body are mainly made of high G-Cr bearing steel. Listed below are compositions of
material for bearing ring and roller body.

Brass cage
Cut brass cage is adopted in small and medium bearings. However, brass cage is not suitable for compressors
with ammonia cooling due to potential seasonal cracking of brass. It is recommended to replace it with iron cage.
Nylon Cage
According to the type and usage of bearings, nylon cages
are widely adopted, but they are inappropriate for
environments where the temperature is above 120℃ or
below 40℃. Most of cast molding cages adopt nylon PA66
material, with or without glass fiber reinforcement whose
advantage is a good combination of strength and
elasticity.
Mechanism of nylon material including strength, elasticity and other
elements, hinged on ambient temperature and degree of aging. The most
important factors determining this kind of aging behavior are temperature,
time and contact media (lubricant). The aging relation of glass fiber
reinforcement nylon PA66 is shown as the right chart. Cage life is shortened
in the wake of the rise of temperature and corrosiveness of lubricant,
because the applicability of nylon cage depends on the operation conditions
and life requirements.
Material for dust shield
CBB.F&D bearings use cold-rolled tin plate as the standard material for dust shields, but also use stainless
steel of AISI- 300 specification at times.
Material for seal ring
Seal rings are mainly made of NBR. For high temperature, fluoro rubbers and silicon rubbers are widely used as
well.

Warning! Fluoro rubber is safe and harmless under normal working condition of below 200℃, but it will give off smoke if the
temperature exceeds the ultimate temperature of 300℃ that is equivalent to flame for cutting steel tubes. In halation
of the smoke is harmful to human bodies including eyes. In addition, the smoke should be avoided to contact skin.

3. Accuracy of Bearing
23 Accuracy of bearing includes dimensional accuracy and rotation accuracy, determined by ISO or JIS Standard
(Accuracy of Roller Bearings). Dimensional accuracy indicates accuracy standard required for bearing
installation into shaft or bearing housing. Rotation accuracy means allowed limit bounce during the bearing
operation .
Comparison table for accuracy grades according to various industrial standards
According to dimension tolerance and rotation accuracy, accuracy grade of CBB.F&D deep groove ball
bearings ranges from ABEC-1 to ABEC-7. ABEC-1 is standard grade, ABEC-3 is higher grade, and ABEC-5
above is used for special purposes. These tolerance grades are set in line with international standard IS0492.

4. Internal Clearance
4.1 Radial clearance
29 Internal clearance of bearing is referred to displacement
produced when either inner or outer ring is fixed to make the
other one move. Displacement produced by radial movement
refers to radial clearance, while displacement produced by
axial travel is called axial clearance (see right figure) In
determination of internal clearance of bearing, in order to
obtain a stable measured value, specified measured load will
generally be applied to bearing. As a consequence, measured
internal clearance is more than actual clearance (referred to as
theoretical clearance), namely increases elastic deformation
produced by measure load. In general, internal clearance of
bearing is represented by theoretical clearance. Internal
clearance of bearing will have an influence on bearing
properties (service life, temperature rise, noise, vibration, etc.)
Internal radial clearance Internal axial clearance
Radial clearance of deep groove ball bearing (without load)

5. Lubrication of Bearings
5.1 Components of grease
31 Lubrication of bearings aims to form a layer of thin oil film on the surface of bearing ring and roller. The purpose of
lubrication is to avoid direct contact of metal, thus eliminating the chance of abrasion to prolong bearing's life.
Besides, lubricant can reduce noise and friction in operation of bearings, improving operation performance and
protecting the bearing away from abrasion and dissipate heat.
Commonly used lubricants include lubrication oil and grease. Lubricant should be correctly selected based on
various applications and different environments to optimize bearing properties.
Grease lubrication
Lipid lubricants are much easier to use than oil lubricants. Due to its viscosity,
grease is more durable and only needs simple sealing equipment to contain.
Grease is hard to be changed, because the usual approach of it is to press
grease into device to make fresh grease squeeze used grease out. General
speaking, grease with low viscosity primary oil is more suitable for high speed
operations at low temperature, while grease with high viscosity primary oil is
suitable for heavy load.
Oil lubrication
Oil lubrication is more suitable for applications under conditions of high speed
and high temperature, effectively taking the heat generated in operation of
bearings away. Viscosity of oil determines the effects of oil lubrication. Low
viscosity will lead to inadequate formation of oil film, while high viscosity will
increase viscous drag and temperature. In general, the higher rotational
speed is, the lower viscosity of lubricant oil will be; the larger load is, the
higher viscosity of lubricant oil will be.
Grease lubrication
Oil lubrication
Basic components of grease are primary oil, thickener and additive.
Primary oil: Lubricate
Thickener: Maintain grease

Additive: Improve grease
performance
Grease structure chart Grease component
Primary oil
In grease, primary oil accounts for 75—96%, in mass fraction. The performance of grease mainly relies on the
nature of primary oil. Particularly when it is with cold flow property and at high temperature, its service life is
bound up with primary oil. Grease with low viscosity primary oil is usually applicable to low temperature and low
load, white lubrication grease with high viscosity primary oil is applied to high temperature and high load. Primary
oil used in grease includes mineral oil and synthetic oil.The commonly used synthetic primary oils contain lipid
oil, synthetic hydrocarbon oil, perfluoropolyether, silicon oil and PPO, etc.

Base oil

5.2 Rolling torque, grease properties and filling amount
32
Thickener
Thickener generally accounts for 4〜20% in mass fraction. Its functions are to suspend primary oil, reduce the
flow of primary oil, and increase adhesion of oil to friction surface. Thickener has two categories: metallic soap
base and non-metallic soap base. Critical operating temperature, mechanical stability, water resistance and
other properties of grease are determined by thickener, for example, sodium soap base can react with water to
form a kind of latex, which can not be applied to running bearing in the atmosphere of high temperature.
Additive
In grease, primary oil accounts for 0.5 ~10% in mass fraction, which is used for the improvement of operating
performance and life of grease. According to the classification by function, it can be divided into thickener (strong
adhesion), antioxidant, extreme-pressure additive, corrosion inhibitor, etc.
Grease parameters (viscosity, penetration) and its filling amount have an influence on rolling torque of bearings
with further affect rotation at speed, leading to a temperature rise.
Generally, the increase of filling amount of lubricant and turning moment will cause temperature rise and velocity
fluctuation. With the same grease filling amount, if viscosity is higher, rolling torque will be larger correspondingly.
Listed below are a few problems as a result of the increase of rolling torque.
Type Description Causes Countermeasures

requirement of velocity

designed velocity at times

Velocity fluctuates
Rotation of bearing causes lubricant to
be excessively agitated and then
produces shearing effect, thus causing
temperature rise
Grease overfilled
Grease overfilled; lubricant with high
working penetration will also give rise to
this problem

Decrease filling amount of
grease, use groove type
grease, use grease with high
softness, etc.
Note: Penetration is a kind of measurement specifying tightness of lubrication grease. The measuring device
used is an inner ring with specified weight and shape, and penetration is the depth of penetrating into this inner
ring (in 1/10mm)。
NLGL model ASTM working penetration
Grease is differentiated by code
for different manufacturers. Code
250 and 300 calcium base grease
and ferry grease generally use
penetration (25C). while most of
multi-purpose greases use NLGL
model such as 0,1 and 2.
5.3 Grease brands and features

6.Vibration and Noise
6.1 Influence factors on vibration and noise
35 Other than load, speed, life and other basic bearing requirements, low noise and vibration have become
increasingly important in practical applications. As we all know, overly vibration can result in early failure of
bearings, and intensified vibration will increase energy consumption; on the other hand, high noise will ruin the
living environment, either to individuals or families. For this reason, it is of vital importance for bearings in a
sound operation to find out the source of vibration and noise and figure it out.

performance
CBB.F&D analyses each influence factor on vibration and noise of bearings by means of Andrew Vibrometer,
effectively helping to manufacture bearings with the features of low vibration and noise.
Bearing ring factor
In rotation, bearing roller rolls on the raceway and makes a kind of steady and continuous noise, which is
generally called raceway noise. Raceway noise would directly increase the vibration and noise of bearings. Such
noise arises from the natural vibration of bearing ring as a result of loading. Vibration and noise of bearings can
be lowered by improving circularity, waviness and other accuracy levels of bearing ring groove.In analysis of
surface accuracy of bearing ring. CBB.F&D analyze circularity and waviness of bearing ring with RONDCOM
31C Circular Division Tester to detect the waviness within a few nanometers to provide a powerful guarantee for
Quality Engineers to improve the quality of products.
Steel ball factor
Vibration value and surface accuracy of steel ball have a direct influence on the generation of vibration and noise
of bearing. It is required by CBB.F&D that the steel balls made by the manufacturer shall have a qualified
vibration value and a good surface accuracy by improving the requirements of circularity and waviness, which
means surface of steel balls observed under a 100x microscope shall not have scratches, scuffing, nicking and
other defects, considered as the prerequisite achieve low vibration and noise of bearing.

Circularity
6.2 Increase of vibration value and countermeasures
IATF16949 / IS09001 / IS014001 / IS045001
36
Cage factor
During the rotation of bearing, both free vibration of the cage and its collision with roller element will make a
noise, which is often called cage noise. Such noise will directly increase the vibration and noise of bearing, but it
can be ameliorated by improving manufacturing accuracy of cage as well as optimizing its appropriate clearance
and movement value. CBB.F&D use cages offered by the manufacturers who all have a state-of-the-art
production process and high manufacturing level. In terms of movement value of cages, dozens of experiments
have been done and a desired value was obtained, providing help in the reduction of vibration and noise of
bearing.
Cleanliness factor
Poor cleaning of bearings will directly increase their vibration and noise. Hence, it is particularly important for the
improvement of bearing cleanliness to actively take advanced cleaning technologies and perform effective and
thorough cleaning for components and assembled products. CBB.F&D use the advanced vacuum
degasification cleaning technology for effective cleaning of components of bearing; for the cleaning of
assembled products, cleaning equipment with vacuum degasification ultrasonic process significantly improves
the cleanliness of bearing, thus reducing the vibration and noise of bearing.
Grease factor
Grease, specifically to bearing, plays a key role in the reduction of vibration and noise. Grease of excellent
properties not only extends the bearing life, but also reduces vibration and noise of bearing. Selection of bearing
grease is particularly important for motors that have a special requirement for noise. CBB.F&D can select
various greases for customers in accordance with their different usage requirements, enabling vibration and
noise of bearing to fully satisfy customer's special requirements.
CBB.F&D conducts 100 percent detection of noise and vibration of each ex-factory product. Besides, CBB.F&D
recently have significantly improved the design of deep groove ball bearings, further downgrading vibration and
noise. Customers may pay extra attention to the following conditions.
