Description
This spherical roller bearing accommodates angular misalignment between shaft and housing while carrying combined radial and axial loads. Bore diameter is 240.0 mm, outside diameter 320.0 mm, width 60.0 mm, with a net mass of 12.935 kg. The tapered bore is designated by bore type K, intended for mounting with an adapter or withdrawal sleeve. Limiting speed is 2440 1/min and reference speed 1310 1/min, defining the thermal and mechanical speed boundaries for operation. Internal clearance is C3 (Group 3), wider than normal clearance, which compensates for interference fit on the tapered bore and for thermal expansion during operation. The cage is designated MB, a machined brass cage guided on the rolling elements, suited for symmetric three-rib construction as noted in the design. Relubrication is standard, allowing grease replenishment through the bearing during service without dismounting.
For mounting this bearing
