Caged roller followers can function directly over a hardened and ground shaft (HRc 58 min, sixteen rms min surface end) or can be used with matching internal rings. Operating without having an inner ring yields the biggest possible shaft diameter with best toughness and rigidity.
A stress angle is established concerning the normal to pitch curve and the line of movement of the follower.
For eccentric stud bearings, the eccentric bushing should suit loosely within the housing bore so it may be modified. The housing need to be not less than 0.
Models using a thick outer ring normally have a small radial hole, providing them superb load capacity in addition to a bigger power to reduce effect loads and dampen shocks and vibrations.
