Caged roller followers provide large internal grease storage capacity for applications where relubrication is infrequent. Cage guided rollers and a very heavy outer ring cross section permit operation at high loads and high speeds. Caged roller followers are avail able with and with out seals. The unsealed design provides the additional advantages of very low friction to prevent skidding in lightly loaded applications and provides for flow-through lubrication. Caged roller followers normally mount directly on a hardened and ground pin. RBC® offers a line of Precision Ground Inner Rings to simplify application of caged roller followers.
