Bearings in these applications are subjected to very severe operating conditions. The shaking actions of vibrating equipment subjects the bearings to very heavy loads, including impact loads. Additional load is created by higher “g” forces generated by acceleration in the application. Bearings are higher speed operated. Furthermore, these kinds of bearings are developed to increase the lifetime of bearings in contaminated environments.

KFB designs special spherical roller bearings – MAC4F80 – to operate under severe conditions. Special KFB spherical roller bearings for vibrating equipment are available in 22300 and 23300 series. The clearance is similar to C4, but the lower third of C4 range is eliminated for better control of the bearing clearance after mounting.
