Industrial SNW 20x3.7 16 16 Adapter Sleeve Bearing

SNW 20x3.7/16/16 Adapter Sleeve Bearing is a steel adapter sleeve for SKF SNW-series bearing assemblies that enables a standard shaft to be used in pillow block housings. The bore diameter is 3.4375 inches (87.31 mm), matching the SNW-20 family, and the 16/16 variant includes a locknut and lock washer for secure retention of the sleeve in the bearing bore. The SNW-20 adapter sleeve is designed to work with the accompanying bearing components in SNW assemblies, allowing the bearing to be pressed onto the adapter sleeve or a withdrawal sleeve to be used during installation. This construction yields a robust, compact solution for mounting bearings on shafts in industrial equipment. Common applications include conveyor and machine tool drives, motors, and other machinery requiring reliable shaft-to-bearing alignment in pillow block configurations. By using a steel adapter sleeve from the SNW family, technicians can achieve precise fit and durable performance in demanding environments.
