Four-point contact ball bearings
Improve steering brake and clutch reliability
For mining and mineral processing machinery, increasing reliability and productivity is a constant challenge. The SKF four-point contact ball bearing solution makes it much easier for transmission, steering brake and clutch applications.
SKF four-point contact ball bearings meet the requirements of high frequency steering brake and clutch use. Their small axial clearance and high stiffness lead to increased reliability and productivity.
SKF four-point contact ball bearings
Robust materials and design
SKF four-point contact ball bearings have undergone a unique SKF heat treatment to provide outstanding strength, stiffness and wear-resistance. An improved brass cage is lighter, to reduce inertia forces and provide better ball guidance. Lightweight PEEK plastic cages with the durability and performance of brass cages are also available.
A shoulder recess on the inner ring of the bearing facilitates dismounting, provides additional lubrication improvements, and a redesigned raceway shoulder transition makes the bearings capable of carrying increased thrust loads.
- Extend bearing service life
- Handle heavier axial loads
- Cut lubricant consumption
- Reduce noise and vibration levels
- Reduce heat generated by the bearing
