IKO cam follower data

IKO cam follower

Fit

The tables show recommended tolerances of mounting holes for IKO Cam Follower studs. Since the Cam Follower is supported in a cantilever position, the mounting hole diameter should be prepared without play between the stud and the hole especially when heavy shock loads are applied.

Maximum Allowable Static Load

The applicable load on IKO Cam Followers is, in some cases, limited by the bending strength and shear strength of the stud and the strength of the outer ring instead of the load rating of the needle roller bearing. Therefore, the maximum allowable static load that is limited by these strengths is specified.

Track Capacity

Track capacity is defined as the load which can be continuously applied on a IKO Cam Follower placed on a steel cam guide surface without causing 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 capacities shown in Tables below are applicable when the hardness of the mating cam guide surface is 40HRC (Tensile strength 1250N/mm2). 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 Table (track capacity factor).

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.

For lubrication between the outer ring and the mating cam guide surface, C-Lube Unit for IKO Cam Followers is recommended.

Allowable Rotational Speed

The allowable rotational speed of IKO Cam Followers is affected by mounting and operating conditions. For d1n values with only pure radial load applied, use the maximum values in Table below or lower as a guideline. Under actual operating conditions, use the recommended d1n values in Table below as a guideline in consideration of the effect of axial loads.
