Retaining RingThis aftermarket retaining ring replaces the equivalent OEM component on lift trucks where the factory part has worn, failed, or simply become hard to source. Retaining rings and circlips hold bearings, gears, and seals onto shafts and inside bores, and a missing or weak ring leads to expensive collateral damage when components walk out of position. Customers are usually fleet managers, dock supervisors, and service technicians keeping legacy lift trucks running well past their original service window.
