Description:
This listing is for one ZEN NKIS45 needle roller bearing with inner ring.

The NKIS45 is a heavy-series machined needle roller bearing with an inner ring, open design, sheet steel cage, and lubrication groove with lubrication holes. It is designed to provide high radial load capacity in a compact bearing section.

Because this bearing includes an inner ring, it is suitable for applications where the shaft cannot be used directly as the raceway or where a hardened and ground precision raceway is required.

Needle roller bearings are commonly used in gearboxes, transmissions, pumps, compressors, agricultural equipment, construction machinery, industrial machinery, and other compact high-radial-load applications.
