Technical Description
Description of shape
The KMF-Ball thrust bearing – AXIAL-SLIM-SPLITBEARING uses a four point geometry. Due to these
four contact points (presure angle 90°) this axial
thrust ball bearing has an extremely high axial Basic
load ratings in relation to the small bearing cross-cut.
Axial thrust ball bearings are mostly so called vertical
bearings (turning axes vertical) and can not transmit
any radial loads.
These bearings are no self holding units. The assembly of the bearing parts (bearing rings, balls and
cage) can be done separately and is for bigger diameters more easy.
Materials
The ball thrust bearings of the type series PBAU, PBAA,
PBAC and PBAD are corrosion resistant. Axial bearing
rings are made of stainless steel X46Cr13 (material
code 1.4034). The cage is made of plastic.
Operating conditions
The temperature limits of the standard bearing in
continuous operation are -40°C and +100°C, temporary up to +120°C.

KUNSTSTOFF-METALL-FORMTEILE
CROSSED-ROLLER-SLIM-SPLIT-BEARING
Description of shape
Crossed roller bearings are single row cylindrical roller
bearings and can take radial loads, double sided acting axial loads as well as moment loads.
The raceway system consists of cylinder rollers, which
are alternately arranged by 90°.
The KMF-CROSSED-ROLLER-SLIM-SPLIT-BEARING uses
splitted bearing rings as the KMF-SLIM-SPLIT-BEARING, so that the biggest possible cylindrical rollers
could be integrated in this special bearing shape with
the smallest bearing cross-cut. A crossed roller cage
with holded and guided rollers causes less friction
in the raceway system and enables therefore higher
speeds. Furthermore the special shape of the cage
guarantees a labyrinth sealing of the bearing gap,
and therefor protects the raceway system, similar to a
sealing system, of leaving the bearing grease and the
entry of rough contamination.
The KMF-CROSSED-ROLLER-SLIM-SPLIT-BEARING
is offered with a bearing cross-cut of 8,0 x 8,0 mm,
named PSX series. Due to this small bearing cross-cut
the connecting parts can be designed very simple.
So, the KMF-Crossed roller bearing offers many advantages regarding design and function.
Because of the maximum possible amount of
rollers, the integration of the cage the given line contact between the rollers and the raceway, the elastic
deformation of crossed roller bearings is small. So this
bearings have an extremely high stiffness, especially
in axial direction, which can be increased by setting
the preload higher. So, the function can be fitted to
the requirements of each application individually.
KMF can supply all bearing types of the complete diameter range of each type series within short terms.
Also all other dimensions beneath the preferred series

Features
• Considerably simplification of constructions with angular roller bearings and their connecting parts (economic construction of the connecting parts)
• Free choice of material for the connecting parts,
e. g. aluminium
• Corrosion resistant and low maintenance
• High static and dynamic Basic load ratings at maximal stiffnes (low deformation)
• Low Mass
• Easy to install
• Dimensions beneath preferred series can be supplied
within short terms
Materials
The bearings are made of stainless steel X46Cr13 (material code 1.4034). The seperator is made of Polyamide 12.
Operating conditions
The temperature limits of the standard bearing in
continuous operation are -40°C and +100°C, for short
periods up to +120°C.
Description of shape
Anguler roller bearings are generally in it’s foundation
engineering form single-row roller bearings. Constructing a new design using this type of bearings, the
angular roller bearing can’t be used alone however,
but as a combined bearing pair with a second bearing.
For the transmission of axial-, radial-, and moment
loads, the angular roller bearing can just be used in
a combined version.
Most commonly this bearing is used in a comnined
version as a bearing pair (two angular roller systems)
in a face-to-face or back-to-back-arrangment. The
choose of the arrangment depands on the conditions
of the construction and the load positions.
KMF-ANGULAR-ROLLER-BEARINGS are made as all
KMF-SLIM-SPLIT-BEARINGS and constist therefore of
two non-cutting manufactured and opened bearing rings, which are completed with a separator strip
filled with cylinder rollers.
All rolling elements are arranged in one running direction, the pressure angle is 45°.
The separator strip with holden and guided rolling
elements causes due to its special shape a cover of
the bearing gap and protects therefore the raceway
sytem for entering of rough dirt and on the other side,
it makes it more difficult for the bearing grease to get
out of the raceway system.
KMF-ANGULAR-ROLLER-BEARINGS can be supplied in
two different types. The type series PSR-08 with radial
manufactured bearing rings and the type series PSA08 with axial manufactured bearing rings. Both have
in commen the same bearing cross cut of 8 x 8 mm.
The type series PSR-08 is the prefered type series in
this bearing range, as it offers a more simple and easier to manufacture construction. This high stiffness
bearing solution with its high load capacities is integrated espacially in applications which require higher
accuracy and a smooth running wthout heavier noise
development. The need for specially paired bearings,
as it is common at conventional bearings is not given.
KMF can supply all bearing types of the complete
diameter range within the prefered series and above
in short terms. Also all sizes in between the prefered
series can be realized whithin short terms.

KUNSTSTOFF-METALL-FORMTEILE Important notices for all types of bearings
Mounting and dismounting of bearings
Due to its opened bearing rings and the cage with
holded and guided rolling elements, the fitting of the
SLIM-SPLIT-BEARING is simple. Compared to common massive bearings it is not neccessary to press fit
slimsplit bearings. Due to the structural shape of this
bearing. It easily can be mounted and dismounted. It
also does not require certain tools or thermal support.
So, turned bearing fits with H- or h7-fits for shaft and
bore tolerances (see fitted dimensions) suffice to contain a bearing.
Precision
The bearing rings of the type series SLIM-SPLIT-BEARING are very accurate in shape. The difference of the
even-thickness between raceway and inside or outside diameter is really small.
That´s why the axial radial precision of the bearings is
greatly influenced by the precision of the connecting
parts. The connecting parts should be constructed in
a way that all diameters and faces that stay in relation
to each other are machined in one spanning operation, if possible. So, the customer is able to define and
manufacture the demands on precision on his own.
Bearing clearance
The SLIM-SPLIT-BEARING has no fixed clearance in the
bearing and the preload of the bearing is not defined.
Either this can be adjusted by the customer directly
by determining the shaft and bore tolerances of the
bearing fits.
In the standard version and with given fitted tolerances, the SLIM-SPLIT-BEARING is slightly preloaded
in the raceway system. This means that even if tolerances are used to the maximum, no clearance in the
bearing is given. Depending on the application and
the specific demands, a clearance can be given by
adjusting the shaft and bore tolerances in order to
reduce the starting torques. Also the tolerances can
be adjusted in order to increase the preload, which
increases the starting torque of the bearings drastically. If insert rooms should be given e. g. a competitive products shall be replaced, and therefore can´t
be adjusted, the clearance in the bearing can be adjusted. This adjustment is achieved by using slightly
bigger or smaller rolling elements.

KUNSTSTOFF-METALL-FORMTEILE Important notices for all types of bearings
For different demands on a bearing type, differently
colored cage strips with different sorts of rolling
elements can be used.
These diffrent colors make it easy to find the most
suitable bearing version.
Lubrication
In order to increase the nominal service life, Lubrication is an important criteria.
For 90 % of all bearing applications in standard
operations, grease is sufficient.
Grease of the consistency-class 2 and 3 (acc. to DIN
51818) is preferred. The grease prevents the direct
contact between rolling element, raceway and cage
and minimises therefore the friction. This minimises
the abrasion and increases lifetime.
As the lubricant for KMF-SLIM-SPLIT-BEARING has not
the function to protect the bearing from corrosion,
relatively small amounts of grease is sufficient for a
reliable function.
The KMF-SLIM-SPLIT-BEARING is equipped standardly
with a pregreasing using ALVANIA EP2 (Shell), which
functions as a permanent lubrication at normal operating conditions. That´s why no targets for lubricating
intervals or lubricating amounts are given. KMF-bearings require low maintenance and can be considered
for normal slewing operations as maintenance free.
For special applications, the KMF-SLIM-SPLITBEARING can be equipped with special greases
according to customers demands.
In order to differ these versions from the standard
bearings, a short sign is added to the KMF-type. Some
examples at the right side:

The Conrad-Filling-Method
The picture on the left side shows how conventional bearings have to be assembled; this way
is also known as the Conrad-Filling-Method. The
bearing inner ring is placed excentrically in order
to cause a bigger bearing gap on the opposite
side. Using this bigger bearing gap, the balls are
integrated into the raceway system. This bearing
gap determines and fixes the maximum amount
and the maximum diameter of the balls that can
be integrated into the bearing.
After that a snap-over cage strip with large ball
divisions is integrated in order to place the balls
equally in the raceway system and prevent them
of touching and running against each other.
Due to this only possibility of assembling a conventional bearing, only a few, and compared to
the bearing cross-cut, relatively small balls can be
integrated. This fact influences the static dynamic
load capacities negatively.

The KMF- Method
The SLIM-SPLIT-BEARING is only manufactured
with splitted bearing rings. Beneath the adjustability of the bearing clearance and the bearing preload, there are additional advantages:
The bearing can be fittted more easily in the connecting parts and great advantages are given during the assembly.
Besides the quality advantages that are offered
by our products, they also offer price advantages due to our manufacturing technology and
easy assembly.
An automatically filled cage strip is placed on
the inner ring, the outer ring is placed in assembly condition and has just to be pressed
slightly over the inner ring and the separator.
Due to this filling method, KMF is able to integrate
much more and much bigger balls in the same
cross-cut of the bearing.
This greatly influences our static and dynamic
load capacities compared to the equivalent competition bearings.
The cage strips are filled with different ball diameters.
Different colors helps differing the individual diameters.

Slewing bearing – SLIM-SPLIT-BEARING
KMF-Thin Ring Bearing-Slewing bearing
Light silent and combined loadable
Due to increasing automating in many industries, e.
g. the semiconductor industry more space saving insert elements or thin ring bearings are required. From
direct driven rotary tables to simple handling tools
space and Mass saving as well as precised bearing
units are requested.
In order to fulfill these market needs, KMF offers a
large variety of bearing elements like wire ball bearings, SLIM-SPLIT-BEARINGs, axial bearing washers and
axial roller and cage assemblies as insert elements for
direct integration in customers con-structions.
Actually this delivery programm is increased by the
slewing bearing assembly YKT, which are complete
ready to assemble and pregreased bearing units.
The raceway system consists of two axial thrust ball
bearings type PBAU with four point geometry. This
bearing design is able to take loads from all directions
(axial and radial), as well as moment loads.
Typically for insert elements is the relatively small
bearing hight of 14 mm of the YKT bearing series.
The both axial thrust ball bearing, which are forming
the raceway system, are undependant of the diameter; this guarantees a stable bearing cross-cut of
only 37,5 x 20 mm, which is valid for the complete
preferred series from bore diameter 100 to 450 mm.
Furthermore this system offers the possibility of manufacturing types between preferred series as well as
slight changes to bearing shape.
KMF-Slewing bearing – SLIM-SPLIT-BEARING with it´s
extremely hight integrated in constructions, which
have not sufficient space for conventional catalogue
bearings.
The ready to assemble easy mounting and easy to
maintain bearing units type series YKT are fixed and
screwed with the connecting parts via the bearing
centering (see tabl of dimensions).
The play and the preload in the bearing is adjustable.
The shape of the bearing with its two raceway systems guarantees a stable running culture with small
starting torques and small noise developement. The
starting torque depends on the axial preload; increasing the preload increases threfore the torque.

Despite of the filigree construction of the KMF slewing bearings, they are nevertheless constructed
according to the principle of economy. Different special option increase the application spectrum and assist individual construction demands
without changing basic pricings considerably.
Bearing units of the type series YKT are offered in different versions, using bearing rings made of steel or
completely corrosion resistant. This completely corrosion resistant version has the short sign „SS“ for stainless steel, the eloxated light metal version the short
sign „AL “ for aluminium.
Furthermore offers the light metal version naturally
the advantage of the Mass decrease of up to 66 %
compared with the steel version.
Additionally, changes to the bore plan can be realised
as well as lubrication bores.
Spur-toothed bearing inner and outer rings
belong to the enhanced standard version as
well as worm gear toothing for direct drives.
Additionally externally flanged or integrated slip ring
solutions for power transmission from the static to
the dynamic bearing ring is possible.
The KMF-Slewing bearing – SLIM-SPLIT-BEARING is
suitable for many application areas, e. g. clean room,
medicine- and food industry due to special material
combinations (corrosion resistant steel, light metal,
ceramic, plastics).
