Track capacity is defined as the load which can be continuously applied on a Cam Follower placed on a steel track surface without causing deformation and indentation
(dent) on the track surface. The track capacities shown in Table 1 are applicable when the hardness of the mating track surface differs from HRC40, the track capacity is
obtained by multiplying the value with a track capacity factor shown in Table 2.
If lubrication between the outer ring and the mating track surface is insufficient, seizure and/or wear may occur depending on the application. Therefore, it is suggested that
attention should be paid to both lubrication and surface roughness of the mating track especially in case of high speed rotation such as cam mechanisms.
Allowable Rotational Speed is affected by mounting and operating conditions. The d1n values in general operation under pure radial load are shown below for reference.
It is recommended to use 1⁄10 of the table values in actual applications taking account of axial loads that may be applied.
d1 x n Values where d1 = Stud Diameter (mm) and n = Number of Rotations per minute (Rpm)
Max d1 x n Values With cage Type = 84,000 d1n (with grease lubricant); Full Complement Type = 42,000 d1n (with grease lubricant).
Material
Carbon Steel. Seals: Special synthetic rubber assembled in the outer ring.
Other Info.
Hexagon socket heads are a new design. Customers should note that screwdriver
slotted examples (pictured right) may be supplied while stocks last. Please check
with Sales if this issue is important.
Stud designed to fit H7 housing.
Notes
(§) It is also applicable to Full complement type, with hexagon hole type and
sealed type.
(§§) Only representative types are shown in the table, but applicable to all metric sizes.

Track capacity is defined as the load which can be continuously applied on a Cam Follower placed on a steel track surface without causing deformation and indentation (dent) on
the track surface. The track capacities shown in Table 1 are applicable when the hardness of the mating track surface differs from HRC40, the track capacity is obtained by multiplying
the value with a track capacity factor shown in Table 2.
If lubrication between the outer ring and the mating track surface is insufficient, seizure and/or wear may occur depending on the application. Therefore, it is suggested that
attention should be paid to both lubrication and surface roughness of the mating track especially in case of high speed rotation such as cam mechanisms.
Allowable Rotational Speed is affected by mounting and operating conditions. The d1n values in general operation under pure radial load are shown below for reference.
It is recommended to use 1⁄10 of the table values in actual applications taking account of axial loads that may be applied.
d1 x n Values where d1 = Stud Diameter (mm) and n = Number of Rotations per minute (Rpm)
Max d1 x n Values With cage Type = 84,000 d1n (with grease lubricant); Full Complement Type = 42,000 d1n (with grease lubricant).
Notes
(§) It is also applicable to Full complement type, with hexagon hole type and sealed type.
(§§) Only representative types are shown in the table, but applicable to all metric sizes.

Table 5: Grease Prepacked Cam Followers and Allowable Temperature Range
Grease-prepacked Cam Followers and allowable temperature range are shown in Table 5. A good quality lithium soap based grease is prepacked.
For Cam Followers without prepacked grease, grease should be packed through the oil hole in the stud before use. If they are used without grease, wear of rolling parts may take place, leading to short
bearing life.

Mounting
T E C H N I C A L
❶
Make the centre axis of mounting hole perpendicular to the moving direction
of the Cam Follower and match the side shoulder accurately with the seating
surface indicated by dimension “f” in the dimension tables. (See Fig.1). Then fix
the Cam Follower with the nut. DO NOT hit the flange head of Cam Followers
directly by a hammer, etc. It may lead to bearing failures such as irregular
rotation and cracking.
IKO mark on the flange head of the stud indicates the position of the oil
❷ The
hole on the raceway. Avoid locating the oil hole within the loading zone. It may
lead to short bearing life. (Refer to Fig.2). The hole located in the middle part of
the stud perpendicular to the stud centre axis is used for greasing or locking.
❸
When tightening the nut, the tightening torque should not exceed the values
shown in the dimension tables. If the tightening torque is too large, it is
possible that the threaded portion of the stud will be broken. When there are
possibilities of loosening, a special nut such as a lock nut, a spring washer or a
self-locking nut should be used.
❹
In the case of Solid Eccentric Stud Type Cam Followers and Eccentric Type Cam
Followers, the outer ring position can be adjusted by turning the stud using a
screwdriver or hexagon bar wrench as appropriate. The stud is fixed by a nut
and a spring-washer, etc. The tightening torque should not exceed the values
of maximum tightening torque shown in the dimension tables.
When shock loads are applied and the adjusted eccentric amount has to be
ensured, it is recommended to make holes in the housing, stud and eccentric
collar, and fix the stud with a dowel pin. (Refer to Fig.3). However, when the
stud diameter is less than 8mm (Eccentric collar dia. 11mm), it is difficult to
make a hole in the stud because the stud is through-hardened.
❺
In the case of Eccentric Type Cam Followers, the length of the mounting hole
should be no more than 0.5mm longer than the dimension B3 (Eccentric collar
width) shown in the dimension table. (Refer to Fig.4).
❻
For mounting the Easy Mounting Type Cam Followers, it is recommended to
fix the screw from the upper side to the stepped portion of the stud. (Refer
to Fig.5).
