This spherical roller bearing carries radial loads while accommodating angular misalignment through its two rows of rollers running on a common spherical outer raceway. Main dimensions follow DIN 635-2, with a bore diameter of 110.0 mm, outside diameter of 170.0 mm, and width of 45.0 mm; net mass is 3.678 kg. Design E1A gives an optimized internal geometry, the cage is designated M, and the limiting speed reaches 4200.0 1/min with a reference speed of 3000.0 1/min. Radial internal clearance corresponds to C4 (Group 4), which is wider than standard clearance and suits applications where thermal expansion or shaft deflection needs to be compensated. The cylindrical bore (bore type Z) allows direct mounting on a straight shaft, and the bearing is prepared for standard relubrication, making periodic grease replenishment straightforward during service.
