Rexnord ZD5307 Roller Bearing Insert 3-7/16 Inch

Rexnord 5307U roller bearing insert, 3-7/16 in bore, is an unmounted spherical roller bearing insert in Rexnord's 5000 Series. It accommodates a 3.4375 in shaft diameter, with an outer diameter of 5.9063 in and an overall width of 5.3200 in, and it uses a double setscrew locking collar to secure the bearing to the shaft. Designed for mounting in Rexnord 5000 Series bearing housings — including cartridge blocks and pillow block configurations — this insert provides self-aligning support that tolerates shaft misalignment while carrying radial loads. This 5307U bore option is the standard 3-7/16 in option within the Rexnord 5000 Series inserts and is intended for use with compatible Rexnord cartridge or housing assemblies to form a complete bearing unit.
