SKF · Bearings & Power Transmission · Adapter Sleeves
SKF OSNP31/600X21H adapter sleeve. Tapered sleeve fitting between a straight shaft and a tapered-bore bearing (spherical roller, self-aligning ball, CARB toroidal roller). Combined with a lock nut and locking device, provides tight fit and correct radial internal clearance without shaft shoulders. Standard designation prefix H (metric H2xxx / H3xxx / H30xx / H31xx / H32xx / HE3xx). Dimensioned to ISO 113. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options (material, sealing, cage, precision, clearance, lubricant). Genuine SKF supply carries the SKF logo etch or moulded mark and hologram-authenticated packaging.
