Industrial 5215-U Self-Aligning Roller Bearings

The Rex® 5215U self-aligning roller bearing insert is an unmounted spherical roller bearing designed for Rexnord 5000-series pillow blocks and take-up housings, offering shaft-housing misalignment accommodation and reliable radial load support. It features a 2-15/16 in bore (2.9375 in), an outside diameter of 5.1177 in, and a width of 4.87 in, with a dynamic load rating of 57,750 lb and a static load rating of 71,500 lb. The bearing is equipped with a double setscrew locking collar to secure it to the shaft and is used with Rexnord 5000-series housings such as AMP5215/KP5215-style pillow blocks. As an insert bearing, it requires a compatible housing and provides self-alignment to compensate minor misalignment, making it suitable for industrial machinery where mounting tolerances are challenging.
