This spherical roller bearing accommodates radial loads together with a degree of shaft misalignment, thanks to its two rows of rollers running on a common spherical outer ring raceway. Main dimensions follow DIN 635-2: bore diameter 55.0 mm, outside diameter 100.0 mm, width 25.0 mm, net mass 0.838 kg. Limiting speed is rated at 9000 1/min, with a reference speed of 4650 1/min. The E1 design provides an optimized internal geometry for increased load carrying capacity, and the cylindrical bore is executed in Z bore type. Radial internal clearance is C3 (Group 3), suitable where thermal expansion or shaft deflection requires a larger operating clearance than normal. The JPA cage guides the rollers with a pressed steel construction, and the design includes a standard relubrication feature allowing grease to be replenished during service. No sealing arrangement is specified, so lubricant supply and contamination protection must be provided externally.
