239/850-K-MB

Heavy-duty industrial applications require components that can take a beating from immense radial forces and sudden axial shocks, which is exactly where the 239/850-K-MB spherical roller bearing delivers. This specific model features a massive 850 mm bore, an outside diameter of 1120 mm, and a structural width of 200 mm. Designed with a 1:12 tapered bore-denoted by the 'K' in its part number-the 239/850-K-MB allows for much easier mounting on tapered shafts or adapter sleeves, securing a tight fit that handles heavy vibration. Inside, an inner-ring-guided solid brass cage ('MB') keeps the dual rows of symmetrical rollers perfectly aligned, significantly lowering frictional heat and helping the unit self-align during shaft deflections. Because the 239/850-K-MB boasts a massive static load capacity of 16,400 kN, heavy industries rely on it for critical machinery like mining conveyors, steel mills, and marine propulsion systems where unplanned downtime is out of the question.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
