Rexnord ER22-MHFF Cylindrical Ball Bearing Insert

The Rexnord Sealmaster ER22-MHFF is a mounted, ER-style cylindrical ball bearing insert designed for use in standard ER housings. It features a 1-3/8 in bore, a 2.8350 in outside diameter, and a 1.688 in overall width, with a nylon retainer and set-screw locking for secure, adjustable mounting in compatible housings. The insert is rated up to 8,400 RPM, making it appropriate for medium-duty shaft applications where a replaceable bearing element is preferred. This model combines the precision of a deep-groove ball bearing with the rugged ER geometry to provide dependable rotation in machines that require quick maintenance and straightforward replacement of the worn insert. Specs like the nylon retainer reduce friction and simplify maintenance, while the set-screw locking provides clamping force to prevent axial movement. Designed to partner with Rexnord/Sealmaster ER take-up systems, the ER22-MHFF offers predictable performance and easy installation in machinery that relies on standard ER cylindrical inserts.
