Needle Roller Bearings & Rings

Motion offers a selection of needle roller bearings and rings from leading brands like McGill, INA (Schaeffler), and RBC Bearings. Needle roller bearings use long, thin cylindrical rollers to support radial loads. These needle rollers have a length that is typically three to four times its diameter. Needle roller bearings have a thinner cross section than other roller bearings and are ideal for limited-space applications that require carrying heavy loads. Drawn cup needle roller bearings have a deeply drawn, thin-walled outer ring. Caged drawn cup units contain a one-piece cage to guide and retain the rollers. Full-complement drawn cup units include the maximum number of rollers that can be retained by the outer shell. The drawn design allows for cost-effective accommodation of heavy radial loads. Needle roller and cage assemblies do not contain inner or outer rings. Instead, the self-contained bearing components work with a shaft or housing bore used as a raceway.
