Sealmaster SK-491 Ball Bearing

Sealmaster SK-491 Ball Bearing Insert is a shaft-mounted ball bearing insert designed for use with Sealmaster mounted bearing housings, featuring a 1-3/16 in bore. This insert carries rolling elements that provide a low-friction interface for rotating shafts and forms part of a modular bearing system that allows for straightforward installation in compatible housings. With a 1-3/16 inch bore, the SK-491 is matched to shafts of that diameter when paired with a proper Sealmaster housing and locking method, enabling reliable support for rotating loads in industrial equipment. The SK-491 is intended for use in applications where a standardized, serviceable bearing insert is required, supporting routine maintenance and replacement without changing the entire bearing assembly. By integrating with Sealmaster's line of mounted bearings, it helps create alignable, replaceable bearing solutions for equipment such as conveyors, machines, and other shaft-driven machinery that demand consistent rotation and predictable performance. This insert is compatible with Sealmaster mounting systems and supports long service life in typical industrial use.
