SKF HA2313 Adapter Sleeve Bearing Two and Three Sixteenths Inch Bore

SKF HA2313 is an H23-series adapter sleeve that enables an inch-shaft Y-bearing unit to be mounted on a 2-3/16 inch shaft, providing a precise, repeatable interface that maintains bore alignment and rotational stability in demanding equipment. The sleeve has a 2-3/16 inch bore, an overall length of 65 mm, and a thread interface sized M65x2 to secure the sleeve within the bearing housing, ensuring a proper fit when the components are bolted together. This adapter sleeve is designed for use with SKF Y-bearing inserts and is part of SKF's standard H23 adapter-sleeve lineup that supports inch-size shaft configurations, enabling interchangeability across SKF's range of Y-bearing units and reducing part variety in assemblies. In practice, HA2313 provides the correct bore-to-shaft fit and alignment needed for reliable operation of spherical bearing arrangements in industrial equipment such as conveyors, fans, mixers, and other machinery that rely on robust, accuracy-driven shaft interfaces. The specification combination—2-3/16 in bore, 65 mm length, M65x2 thread—helps ensure compatibility with SKF Y-bearing units and consistent performance when adapting spherical bearings to 2-3/16 inch shafts, simplifying maintenance and inventory for service technicians.
