- Operating Temperature Range: -20°C to +100°C (continuous), 110°C (max).
Supplied pre-packed with grease.
No oil hole is provided.
These are compactly designed bearings, incorporating very thin needle rollers in an outer ring with a small inside diameter.
They are used in electronic devices, OA equipment, small index devices, etc.
Stainless Steel miniature cam followers available, P.O.A.
Further technical information available on request.
Track capacity is defined as the load which can be continuously applied on a Cam Follower placed on a steel cam guide surface without causing any deformation or indentation on the cam guide surface when the outer ring of the cam follower makes contact with the mating cam guide surface (plane). The track load capacities are applicable when the hardness of the mating cam guide surface is 40HRC (Tensile Strength = 1,250Nmm2). When the hardness of the mating cam guide surface differs from 40HRC, the track capacity is obtained by multiplying the value by the track capacity factor shown in the separate table.
If lubrication between the outer ring and the mating cam guide surface is insufficient, seizure and/or wear may occur depending on the application. Therefore, attention must be paid to lubrication and surface roughness of the mating cam guide especially for high-speed rotations 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.
d x n Values where d = Stud Diameter (mm) and n = Number of Rotations per minute (Rpm)
Max d x n Values With cage Type = 84,000 dn (with grease lubricant); Full Complement Type = 42,000 dn (with grease lubricant).
