Compensates for angular misalignment between shaft and housing thanks to its self-aligning ball bearing design with a spherical outer raceway, allowing the inner ring with balls and cage to swivel relative to the outer ring. Bore diameter is 55.0 mm, outside diameter 120.0 mm, width 29.0 mm, net mass 1.58 kg. The bearing runs at a limiting speed of 6100.0 1/min and a reference speed of 5800.0 1/min, fitted with a TVH cage made of glass-fibre reinforced plastic. Radial internal clearance corresponds to C3 (Group 3), giving greater internal clearance than normal, which helps to offset the effects of interference fits and thermal expansion during operation. The plastic TVH cage guides the balls with low friction and contributes to the permissible speed ratings stated above. Bore type Z relates to the raceway geometry of the bearing as specified by the manufacturer. The self-aligning construction makes the bearing suitable where shaft deflection or housing misalignment must be accommodated without inducing additional load on the rolling elements.
