Description
This spherical roller bearing accommodates shaft misalignment through its self-aligning outer raceway design, with two rows of rollers running on a common spherical raceway. Main dimensions follow DIN 635-2: bore diameter 40.0 mm, outside diameter 90.0 mm, width 23.0 mm, net mass 0.722 kg. The bearing reaches a limiting speed of 9800 1/min and a reference speed of 5200 1/min, fitted with a JPA cage and cylindrical bore (type Z). The C3 radial internal clearance (Group 3) provides increased internal clearance to compensate for thermal expansion during operation and interference fit mounting. The E1 design offers optimized internal geometry for extended service life under radial and combined loads. Standard relubrication feature allows regreasing during operation without disassembly, supporting maintenance in applications with continuous duty cycles.
