This spherical roller bearing accommodates angular misalignment between shaft and housing, with two rows of rollers running on a common spherical raceway in the outer ring. Bore diameter is 120.0 mm, outside diameter 260.0 mm, and width 86.0 mm, giving the basic envelope for shaft and housing fit. Mass netto is 21.991 kg, relevant for handling during mounting. Limiting speed is rated at 2850.0 1/min, with a reference speed of 2000.0 1/min based on thermal conditions. The E1 design indicates an optimized internal geometry for extended service life. The C4 radial internal clearance (Group 4) is wider than standard, compensating for interference fits and thermal expansion under load, which suits applications with oscillating loading and shaft deflection. The JPA cage guides the rollers and withstands the dynamic forces generated during misalignment compensation. Bore type Z refers to the raceway geometry as specified by the manufacturer. Standard relubrication feature allows grease replenishment through the bearing during operation without dismounting. The restricted diameter tolerance mentioned for this series supports more precise shaft fitting than the standard tolerance class. The direct dimensional and constructional equivalent is SKF 22324CCJA/W33VA406.
