Description
This spherical roller bearing accommodates angular misalignment and radial loads through its two rows of rollers running on a common spherical outer raceway. Main dimensions follow DIN 635-2: bore diameter 50.0 mm, outside diameter 110.0 mm, width 27.0 mm, net mass 1.29 kg. The bore is tapered at 1:12 (bore type K), allowing mounting on a tapered shaft or with an adapter sleeve, with axial displacement setting the operating clearance. Limiting speed is 9000 1/min, reference speed 5400 1/min, cage is JPA, design E1. Radial internal clearance corresponds to CN (Group N), suitable for standard fit and load conditions without additional clearance adjustment beyond the tapered bore mounting. The tapered bore design permits compensation for shaft deflection and simplifies mounting and dismounting compared to a cylindrical bore. Relubrication is standard, meaning the bearing can be regreased through provided lubrication features during service without disassembly.
