GQZ IR162016 Needle Roller Inner Ring 16×20×16mm Hardened Precision Bushing For Needle Roller Bearing Assembly

The IR162016 precision needle roller bearing inner ring acts as an independent hardened raceway bushing. It is used when the mating shaft cannot be heat‑treated and ground directly. Fine‑ground outer surface provides precise raceway for needle rollers, realizing high radial load capacity under compact installation space.

It is widely matched with needle roller bearings for gear assemblies, transmission mechanisms and compact machinery units.
