This spherical roller bearing carries radial loads combined with oscillating conditions and compensates for shaft misalignment through its two rows of rollers on a common sphered raceway in the outer ring. Bore diameter is 85.0 mm, outside diameter 180.0 mm, width 60.0 mm, and net mass is 7.228 kg. Limiting speed reaches 4100.0 1/min, reference speed 3200.0 1/min. The E1 design provides an optimized internal geometry and roller guidance for extended operating life under the given load conditions. The bearing is supplied with C4 radial internal clearance, larger than normal, which accommodates thermal expansion and shaft deflection during operation. The JPA cage guides the rollers reliably at the stated speed range, and the Z bore type together with the T41D executions supports mounting with restricted diameter tolerances on the shaft seat. Standard relubrication feature allows grease replenishment during service without disassembly, suiting applications where periodic maintenance intervals are planned.
