This barrel roller bearing accommodates radial loads while allowing angular misalignment between the inner and outer rings, owing to the curved rolling elements. The bore diameter is 25.0 mm, outside diameter 52.0 mm, width 15.0 mm, and net mass 0.133 kg. The bearing carries a K tapered bore, is fitted with a TVP cage, and is supplied with C3 radial internal clearance. Limiting speed is rated at 11500 1/min. The tapered K bore allows mounting on an adapter or withdrawal sleeve, simplifying fitting and removal on cylindrical shaft seats. The C3 clearance compensates for thermal expansion during operation and offsets the fit-related reduction in internal clearance after mounting. The self-aligning geometry permits the bearing to tolerate shaft deflection or housing misalignment without generating additional edge stress on the rolling elements.
