Sealmaster ER-22T Ball Insert Bearing

Sealmaster ER-22T is a straight-bore, ER-style ball bearing insert designed to mount in compatible Sealmaster housings and other assemblies that accept a 1-3/8 in bore. The bearing features a 2.835 in outer diameter and a width of 1.750 in, with a 1-3/8 in bore, delivering dependable support for medium-duty drive and conveyor components. Constructed from 52100 bearing steel and black-oxide coated, it combines durability with corrosion resistance in typical shop environments. Locking is provided by SKWEZLOC concentric locking collar, which locks the inner race to the shaft while preserving concentricity and minimizing runout. The ER-22T is rated for approximately 5,782 lb dynamic radial load and 3,493 lb static radial load, making it suitable for belt-driven pulleys, sprockets, and other shaft-mounted applications in light to medium-duty equipment. This insert integrates into standard ER-series mounted-bearings catalogs and distributor inventories, offering reliable performance where a rigid, low-clearance bearing interface is required in a compact form factor.
