Super Heavy Load Capacity

Large diameter spherical roller bearings are designed for extreme heavy load and high-impact working conditions. With optimized internal geometry and high-quality bearing steel, they deliver exceptional dynamic and static load ratings for continuous operation.

Self-Aligning Performance

The spherical design automatically compensates for shaft deflection and misalignment, reducing stress on other components and extending equipment service life.

Cage Options for Different Working Conditions

  • CA Cage (Brass) – Standard one-piece brass cage, suitable for heavy load and moderate speed applications.
  • MB Cage (Machined Brass) – High-strength machined brass cage for severe impact and vibration conditions.
  • CC Cage (Stamped Steel) – Cost-effective steel cage for general industrial applications.

W33 Lubrication & Tapered Bore Options

W33 suffix adds lubrication grooves and holes for better oil flow under high-temperature conditions. K suffix provides tapered bore for easy mounting with adapter sleeve or dismounting with withdrawal sleeve.

Main Applications

Extra large spherical roller bearings are widely used in heavy industry equipment including:

Cement kilns Mining crushers Steel mill machinery Large electric motors Heavy-duty reducers Port machinery Marine propulsion Vibrating screens
