INA 30 mm ID Needle Roller Bearing, 47 mm OD, Sealed, 18 mm Race Width NA4906-2RSR-XL

INA NA4906-2RSR-XL needle roller bearing features a 30 mm inside diameter and 47 mm outside diameter with an 18 mm race width. Designed with sealed ends, it ensures protection against contaminants and enhances service life. This needle bearing supports high to very high radial forces, ideal where drawn cup Needle Roller Bearings with open ends are insufficient but where cylindrical roller bearings are not yet required.

The bearing supports radial loads only and is thus well suited for non-locating bearing applications where axial displacement of the shaft relative to the housing is necessary. Its compact design allows for minimal radial space requirements, especially when used without an inner ring, providing cost-effective and economical bearing arrangements.

With a maximum grease-lubricated speed and limiting speed of 7500 rpm, the bearing performs reliably at high rotational speeds. The needle roller design provides line contact that sustains heavy loads while permitting high speeds. It also compensates for slight misalignments between shaft and housing, providing reliable operation in demanding industrial settings.

This bearing is a Better World product, contributing to extended product life and energy savings, supporting sustainable industrial practices. Its sealed construction ensures long-term durability in mechanical machinery, manufacturing, and other industrial applications requiring reliable radial load support and compact design.

Supports high to very high radial forces with needle roller design. Sealed end type protects the bearing and improves reliability. Race width of 18 mm offers compact bearing arrangement. Permits axial displacement allowing non-locating bearing applications.
