Product Description
239/1250-B-K-MB-C3 is a Double Row Spherical Roller Bearing with dimensions 1250×1630×280 mm and weight 1630 kg, replacing old designation 239/1250BKMBC3. It features the B design with a fixed central rib, a K tapered bore (taper 1:12) for mounting on adapter sleeves, an MB solid brass cage guided on the inner ring, and C3 radial internal clearance. It offers a dynamic load rating of 12000 kN and a static load rating of 32500 kN.
- B fixed central rib improves roller guidance and enhances axial load carrying capacity
- Self-aligning capability adapts to shaft deflection and installation misalignment
- K tapered bore for convenient mounting and dismounting with adapter sleeves
- Solid brass inner ring guided cage guarantees stable operation in heavy shock load conditions
- C3 clearance accommodates thermal expansion under continuous high-temperature working conditions
The bearing delivers stable and reliable shaft support for large mining machinery and port cranes operating under harsh, extremely heavy loads and misalignment conditions. It is widely used in large crushers, mills, rotary kilns, and other heavy industrial applications.
