GQZ NK25/16 Needle Roller Bearing 25×33×16mm Without Inner‑Ring Compact High Radial Load Bearing

The NK25/16 single‑row machined‑ring needle roller bearing is designed without inner ring, two integrated flanges on outer ring for axial guidance, equipped with lubrication hole. Hardened and ground shaft surface acts directly as inner raceway. It delivers high radial load capacity with compact radial cross‑section, permits bidirectional axial displacement, suitable for compact low‑medium‑speed transmission mechanismsSKF 集....

It is widely used in gearboxes, textile machinery and general‑purpose compact mechanical shaft assemblies.
