Description
This spherical roller bearing (23938-S-MB) is built with two rows of rollers running on a common spherical outer ring raceway, which allows the bearing to accommodate angular misalignment between shaft and housing. Main dimensions follow DIN 635-2: bore diameter 190.0 mm, outside diameter 260.0 mm, width 52.0 mm, mass 8.095 kg. Limiting speed is 3150 1/min, reference speed 1750 1/min. The bore type is Z (cylindrical bore), and the cage is machined brass, type MB. Radial internal clearance is CN, Group N, suited for standard fit and load conditions without preload. The S designation marks a relubrication feature, with a groove and holes in the outer ring that allow grease replenishment without dismounting the bearing. The MB cage, guided by the rolling elements, supports stable operation across the stated speed range, while the spherical raceway design allows the bearing to run under shaft deflection and angular misalignment.
