How to choose Cam Followers

Points to check when selecting, with the values for this product (KRV 52 PPA).

  1. 1. Select outer diameter to suit surface and load

    The outer diameter D is the basic dimension that determines the surface pressure on the mating contact surface and the required installation space. Listed products range from 16 to 52 mm. A larger outer diameter lowers the surface pressure and reduces wear on the mating surface. Determine it by checking against the dimensions of the cam groove or rail.

  2. 2. Verify life with dynamic load rating

    This product: Basic dynamic load rating Cr 20,9 kN

    The basic dynamic load rating Cr is the reference value for life calculation. Listed products range from 9 to 78 kN. Even with the same outer diameter, full-complement and high-load types have a higher Cr. Select by calculating the required life from the actual load and rotational speed. If shock loads are present, also check the basic static load rating C0r.

  3. 3. Choose between cylindrical and crowned outer ring

    A crowned (spherical) outer ring reduces edge loading caused by mounting errors and suppresses stress concentration at the outer ring ends. A cylindrical outer ring has a longer contact length and is a shape that easily lowers the surface pressure on the mating surface. Select according to the accuracy of the mating surface and the mounting accuracy.

  4. 4. Confirm mounting with stud diameter and thread

    The stud diameter d and thread designation determine the machining dimensions of the mounting hole and the tightening torque. If the threaded portion is too long, it may not pass through the frame, so check the frame plate thickness and nut position together with the overall length B.

  5. 5. Select eccentric type when position adjustment is required

    With the eccentric stud type, turning the stud shifts the roller position, so the contact and clearance of multiple rollers can be adjusted after assembly. The eccentricity of listed products ranges from 0.25 to 1 mm. Confirm that the required adjustment allowance falls within this range.

  6. 6. Use sealed type in dust and cutting fluid environments

    In environments exposed to dust, cutting fluid, or moisture, selecting a sealed type such as 2RS helps suppress foreign matter ingress and grease leakage. Unsealed types have lower rotational resistance, but they require a maintenance plan such as periodic lubrication through the grease hole.
