Sealmaster ERX-23 HIY self-aligning ball bearing insert, ER style, combines a 52100 bearing steel core with a black oxide coating for durability and a setscrew locking arrangement to secure the shaft. It accepts a 1-7/16 in bore and presents an outer diameter of 2-53/64 in (about 2.859 in) with an outer ring width of 15/16 in, enabling compact mounting in standard ER-style housings. Classified as medium-duty, this insert provides misalignment tolerance to improve shaft alignment in equipment such as conveyors, pumps, and fans.
