Product Description (Listing-Ready)

The FAG NU205-E-XL-M1A-C4 is a single-row cylindrical roller bearing with a two-piece brass cage guided on the outer ring, designed for high radial loads, rigidity, and stable operation at higher speeds. Its caged roller design minimizes roller-to-roller contact, allowing higher speeds and smoother running compared with full-complement cylindrical roller bearings, while the separable ring construction simplifies installation and service.

As an NU design, it supports radial forces only and is typically used as a floating (non-locating) bearing, allowing axial displacement in both directions to accommodate thermal expansion. When combined with HJ angle rings (sold separately), it can be configured to support axial load in one direction.

This version features C4 clearance (higher than C3), making it suitable for applications where greater internal clearance is required due to higher operating temperatures, tighter fits, or thermal growth. As part of FAG’s X-life range, it provides improved performance, reduced heat generation, longer service life, and extended maintenance intervals versus standard designs.
