SealMaster ER-20T Bearing

The Sealmaster ER-20T mounted ball insert bearing is designed for a 1-1/4 in shaft and is built for non-expansion, standard-duty ER-style service in insert applications. It features an outer diameter of 2.8346 in and a width of 1.75 in, with a concentric lock collar to secure the bearing in its housing, and it uses 52100 bearing steel with a black oxide finish, a standard felt seal, and a brass cage. Rated for up to 6,500 rpm, it provides a dynamic load capacity of 5,782 lb and a static load capacity of 3,493 lb, with a -20 to 220 degrees Fahrenheit operating range and a double-sealed closure for added protection. As an insert-only bearing, it is installed into a compatible housing rather than sold as a complete unit, offering a reliable, maintenance-friendly solution for machinery that requires precise radial support and a proven ER-style bore interface.
