Description

This spherical roller bearing accommodates radial loads while compensating for shaft misalignment through its two rows of barrel-shaped rollers running on a common spherical outer ring raceway. Main dimensions follow DIN 635-2: bore diameter 55.0 mm, outside diameter 120.0 mm, width 29.0 mm, net mass 1.62 kg. The E1 design provides an optimized internal geometry, cage is JPA, bore type Z, limiting speed 8100 1/min, reference speed 5100 1/min. Radial internal clearance falls in the CN (Group N) range, suitable for standard fit conditions without preload requirements. The open design with standard relubrication feature allows periodic grease replenishment through the bearing, supporting continuous operation where shaft deflection or housing misalignment must be tolerated without edge loading on the rollers.
