This spherical roller bearing carries radial loads and combined loads while compensating shaft misalignment, thanks to its two rows of rollers running on a common spherical outer raceway. Bore diameter is 140.0 mm, outside diameter 250.0 mm, width 88.0 mm, and net mass is 18.0 kg. The tapered bore, taper 1:12 (bore type K), allows mounting on tapered seats or with a sleeve, giving precise control of the fit and internal clearance during installation. Limiting speed is rated at 2600 1/min, reference speed at 1550 1/min. The design E1A construction combined with a machined cage (cage M) supports higher speeds and reduces friction losses. Radial internal clearance C3 compensates for interference fit tightening and thermal expansion during operation, keeping the bearing properly preloaded under load. Standard relubrication feature allows grease replenishment without dismounting the bearing, which is useful where the bearing runs for extended periods between service intervals.
