The FAG NU203-E-XL-M1A-C3 is a premium single-row cylindrical roller bearing manufactured by Schaeffler. Its high-capacity X-life internal design and robust two-piece solid brass cage provide excellent strength, rigidity and reliable performance in demanding industrial applications.
The NU design incorporates two integral ribs on the outer ring and a ribless, separable inner ring. This arrangement allows axial displacement between the shaft and housing in both directions, making the bearing particularly suitable for use as a non-locating or floating bearing. It can accommodate thermal expansion of the shaft while supporting high radial loads.
The separable construction also makes installation and removal easier, particularly where the inner and outer rings require separate mounting. This open bearing has C3 radial internal clearance, which is greater than normal, and requires suitable lubrication during operation.
