This spherical roller bearing carries radial loads and permits angular misalignment thanks to its self-aligning design. It has a bore diameter of 170.0 mm, outside diameter of 280.0 mm, and width of 109.0 mm, with a net mass of 26.1 kg. The bearing features a tapered bore (K30, taper 1:30) allowing mounting on tapered seats or with adapter/withdrawal sleeves, and main dimensions to DIN 635-2. Limiting speed is 2110.0 1/min, with a reference speed of 1060.0 1/min. The C4 radial internal clearance (Group 4) provides additional clearance to compensate for thermal expansion and fits requiring interference, making the bearing suitable for applications where shaft deflection or misalignment must be accommodated. The JPB cage guides the rollers reliably under these conditions, and the BE design contributes to load distribution across the roller set. Standard relubrication feature allows maintenance through the provided lubrication path during operation.
