Product Description
239/1700-B-MB-C3 is a Double Row Spherical Roller Bearing with dimensions 1700×2180×355 mm and weight 3550 kg, replacing old designation 239/1700BMBC3. It features the B design with a fixed central rib, an MB solid brass cage guided on the inner ring, and C3 radial internal clearance. It offers a dynamic load rating of 19300 kN and a static load rating of 60000 kN.
- B fixed central rib improves roller guidance and axial load bearing performance
- Self-aligning design absorbs shaft deflection and installation misalignment
- Inner ring guided solid brass cage provides long service life under heavy impact loads
- C3 radial clearance accommodates thermal expansion for continuous high-load operation
- Large-size thin cross-section design, suitable for limited installation space
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.
