This spherical roller bearing carries radial loads together with axial loads in both directions and accommodates shaft misalignment thanks to its self-aligning two-row roller design. It has a tapered bore (taper 1:12), bore diameter 170.0 mm, outside diameter 280.0 mm, width 88.0 mm, and a net mass of 20.7 kg. The limiting speed is 2380 1/min, with a reference speed of 1460 1/min. Main dimensions follow DIN 635-2, design E1A, bore type K. The tapered bore allows mounting on an adapter sleeve, giving a defined interference fit without the need for a stepped shaft seat. Radial internal clearance corresponds to CN (Group N), suitable for standard fit and operating conditions without additional clearance adjustment. The M cage, made of machined brass, provides stable roller guidance and supports operation at the stated speed ratings. The bearing is designed for standard relubrication, allowing grease replenishment during service without disassembly.
