Compensating for shaft misalignment, this self-aligning ball bearing features a tapered bore with 1:12 taper (K) for mounting on adapter or withdrawal sleeves, allowing a fixed axial position on the shaft once driven up to the required fit. Bore diameter is 25.0 mm, outside diameter 52.0 mm, width 18.0 mm, and net mass 0.149 kg. The cage is TVH, a glass-fibre reinforced plastic design guided on the balls. Limiting speed is 14400 1/min, reference speed 13400 1/min. Radial internal clearance is C3, greater than standard, compensating for the fit tightness that results from mounting on a tapered seat and for thermal expansion during operation. The tapered bore permits the bearing to accommodate shaft deflection and simplifies dismounting compared with a cylindrical bore fit. No sealing is integrated, so lubricant supply and contamination protection must be provided externally through the housing design.
