Structure and Features

Cam followers are compact and high rigid bearings with stud. It has a structure that an outer ring with built-in

“roller” rolls over a track (raceway) and is utilized as guide roller for cam mechanism or linier motion. The cam

follower is designed with a thick-walled outer ring in order to provide high rigidity to endure heavy load or impact

load at contact portion with the track.

Outer rings have two shapes – crowned outer ring and cylindrical outer ring. The cylindrical outer ring is effective

for heavy duty applications since it contacts with large contact area of the associated objects so that can mitigate

the contact surface pressure. The crowned outer ring is suited for absorbing eccentric load since it absorbs angular

misalignment due to a mount error. They have two internal structures – one with cage and one with full

complement. Caged type cam followers are suited for high speed application, since the guiding feature of cage

enables the rotation of \"rollers\" to be stable. Compared with caged type cam followers, full complement type is

effective for applications with low-speed operation of heavy load due to its larger load rating. Full complement

type also includes double-raw cylindrical roller type which allows moderate axial loading.

Cam followers shall be fixed by tightening hexagon nut at stud thread by holding the stud with screw driver or

hex-wrench.

Cam followers with eccentric axis on the stud thread have an advantage to adjust the variation of mounting

position within its eccentric range, without requesting high machining accuracy of mounting hole position.

Maximum permissive load

Permissive load of cam follower is subjected to change in accordance with bending strength and shear strength of

its stud in addition to standard rating load of needle bearing due to its design with stud. This load is indicated as

maximum permissive load.

Track load capacity

Track load capacity means a permissive load under which the outer ring of cam follower and the mating surface

are allowable to be used over a long period without causing any deformation nor compression mark. Track load

capacity depicted in dimension table indicates a value for which hardness of steel mating material is assumed to

be HRC40. In the case that the hardness of mating material is not HRC40, track load capacity in the dimension table

shall be multiplied by value of track load factor obtained by Figure-1. Track capacity factor

Lubrication

All the JNS cam followers are lubricated with pre-packed high quality lithium soap-based grease grade 2 (RoHS

compliant) so that they are ready to use. For applications requiring high prevention measure against invasion of

foreign matter or leakage of lubricant, products with seal(part conde--UU) which integrate special synthetic lubber

with high abrasion resistance are also available.

Grease shall be packed up to volume approximately one-third to one-half of internal space of bearing. Lubrication

interval varies depending on operation condition. Referential interval may be every six to twenty four months for

cam followers with cages and every one to six months for full complement type with grease in the same type.

Some excessive grease may leak at the beginning of usage or immediately after re-greasing even for the products

with seal. Aging operation period is recommended prior to application in which no contamination by grease is

allowed in and around device. Wipe and clean any leaked extra grease after this operation.

Dedicated grease nipple shall be knocked in onto cam follower by pressing flange portion of the nipple using

fixture shown in Figure-2.

Mounting

Mounting part

Hole for stud shall be perpendicular to mounting surface so as to ensure even contact between outer ring and

rolling surface of mating material. Corner chamfer of hole shall be as small as around C0.5. Counter bore diameter

shall be dimension f or more as described in the dimension table.

Type CF-R with crowned outer ring is recommended in the case of application with insufficient contact between

outer ring and rolling surface of mating material.

Figure-3

Mounting method

● Cam follower shall be mounted so as not to incline against direction of the motion.

● Mounting method to tighten cam follower directly to bracket by adding female thread to it without using nut

as depicted in Figure-4 (A) is NOT recommended. This method may cause damage on stud due to concentration of bending stress in male thread portion in the event of loosening since it is difficult to tighten the stud

sufficiently.

Figure-4

● For application with heavy load, lubrication hole of stud shall be located outside of loading range (on the side

to receive load). Location of the lubrication hole is indicated by “JNS” marking on the side of stud flange. (Refer

to Figure-5)

Hole at the center of stud is used as stopper for tightening or lubricant supply hole for grease lubrication.

Load Load

Figure-5

Precaution for using spring washer

It is important to ensure that spring washer used for mounting cam follower has no burr or sharp edge. Debris

scraped from nut or mounting bracket by burr or shape edge of washer during tightening can invade stud thread

and can cause insufficient tightness or damage to thread.

Tightening torque of stud

Stud of cam follower is subjected to bending stress or tensile stress by bearing load. Tightening torque shall be set

not to exceed the value in the dimension table.

Using double spring washers, double thin nut of JIS B 1181 or special nut with locking feature is recommended in

the case of possible loosening of mounting screw due to vibration or impact shock.

128 NOSE SEIKO CO.,LTD NOSE SEIKO CO.,LTD 129

Mounting of CF-SFU type

Refer to Figure-7 for mounting method of easy mounting of CF-SFU type.

Type CF-SFU is NOT recommended for application in the part subjected to vibration or shock impact as much as

its mounting is simple. Standard cam followers with nut are recommended for application with possible vibration

or shock impact.

Figure-7

Mounting of eccentric cam follower

Adjustment of eccentric shall be performed in accordance with the following procedure.

（1） Insert stud to mounting hole and tighten nut as the stud can turn loosely. Marking of stud shall face location

indicated in Figure-6 in relation to direction of load.

（2） Gap between cam follower and mating contact surface may be adjusted by turning stud using hexagon hole

on the stud head.

（3） After completing adjustment, tighten nut with holding rotation of stud. Make it sure not to exceed maximum

tightening torque of the nut.

Structure and Features

Roller follower is a bearing with integrated “roller” featuring high rigidity. Its primary application is in a guide roller

to have its contacting member travel in linier motion in direction of tangent using rotation of outer ring.

Outer ring of the roller follower is designed with thick ring in order to provide high rigidity to endure heavy load or

impact load at portion to contact with the associated objects.

Type of roller follower mainly consists of separate type, which have separated inner ring and outer ring, and nonseparate type, whose inner ring has fixed side plate.

Also, various types with shapes and structures are available in accordance with application. Outer rings have two types –

crowned outer ring and cylindrical outer ring. The crowned outer ring is suited for absorbing eccentric load since it absorbs

angular misalignment due to a mount error. Cylindrical outer ring is effective for heavy duty since it contacts with large

contact area of the associated objects so that can mitigate the contact surface pressure. They have two internal mechanism

– one with cage and one with full complement. A roller follower with cage is suitable for high speed application since the

guiding feature of cage enables the rotation of \"rollers\" to be stable. Compared with cage type, full complement type is

effective for applications with low-speed operation of heavy load due to its larger load rating. Full complement type also

includes double-raw cylindrical roller type which allows moderate axial loading.

Track load capacity

Track load capacity means a permissive load under which the outer ring of cam follower and the mating surface

are allowable to be used over a long period without causing any deformation nor compression mark. Track load

capacity depicted in dimension table indicates a value for which hardness of contacting steel member is assumed

to be HRC40. In the case that the hardness of contacting member is not HRC40, track load capacity in the

dimension table shall be multiplied by value of track capacity factor obtained by Figure-1. Track capacity factor

Lubrication

All the JNS roller followers are lubricated with pre-packed high quality lithium soap-based grease grade 2 (RoHS

compliant) so that they are ready to use. For applications requiring high prevention measure against invasion of

foreign matter or leakage of lubricant, products with seal (part code--UU) which integrate special synthetic lubber

with high abrasion resistance are also available.

Grease shall be packed up to volume approximately one-third to one-half of internal space of bearing. Lubrication

interval varies depending on operation condition. Referential interval may be every six to twenty four months for

roller followers with cages and every one to six months for full complement type with grease in the same type.

Some excessive grease may leak at the beginning of usage or immediately after re-greasing even for the products

with seal. Aging operation period is recommended prior to application in which no contamination by grease is

allowed in and around device. Wipe and clean any leaked extra grease after this operation.

180 NOSE SEIKO CO.,LTD NOSE SEIKO CO.,LTD 181

Mounting method

To prevent pre-mature failure of roller follower, lubrication hole of inner ring shall be located outside of loading

range (on the side to receive load).

NAST..ZZ Example of mounting

NART..UUR Example of mounting

Mounting

Mounting part

● Thrust load may cause damage to side plate, outer ring or roller follower since it is designed so as to support

load in radial direction. It is recommended to design and assemble to avoid thrust load.

● Application with roller follower without inner ring requires heat treatment and grinding finish of shaft. Surface

hardness of the shaft shall be HRC58 to 64, and surface roughness shall be R a 0.2 μ m or less for this application.

● Side plate of non-separate type roller follower is pressed-in to fix it. Application in a manner to push the side

plate shall be avoided in order to prevent risk of abnormal rotation under external force.

● Crowned outer ring is recommended in the case that contact between the outer ring and contacting member

track surface is not smooth and even.

● When mounting NART, NAST-ZZ and NURT type, dimension \"a\" must be more than it described in dimension

table in order to protect the side plate.
