This self-aligning ball bearing accommodates shaft misalignment through its two rows of balls running on a common sphered outer raceway, allowing the outer ring to tilt relative to the axis without inducing additional load on the balls. Bore diameter is 75.0 mm, outside diameter 160.0 mm, width 55.0 mm, and net mass 5.16 kg. The bearing is fitted with a solid brass cage (M) and carries the internal C3 radial clearance, providing greater internal play than standard to compensate for thermal expansion and shaft deflection. Limiting speed is rated at 6100 1/min, with a reference speed of 5600 1/min. The combination of self-aligning geometry and C3 clearance suits applications where shaft bending or housing misalignment must be tolerated without binding the balls or raising operating temperature. The solid brass cage offers stable ball guidance at the stated speed levels and resists cage wear under the loads typical for this bore and clearance class. The plain cylindrical bore (Z) permits direct mounting on a straight shaft, and the C3 clearance should be matched with the appropriate fit and mounting tolerance to maintain correct running clearance once operating temperature is reached.
