Product Description:

This listing is for one ZEN NK37/20 needle roller bearing.

The ZEN NK37/20 is a machined needle roller bearing with a 37 mm inside diameter, 47 mm outside diameter, and 20 mm width. It is an open bearing with no seals and is designed without an inner ring, allowing it to run directly on a properly hardened and ground shaft raceway.

Needle roller bearings are commonly used where high radial load capacity is required in a compact space. Their slim cross-section makes them suitable for applications where radial space is limited while still requiring reliable load-carrying performance.
