4 Point Contact Ball Bearings

A number of optimized design features enable SKF four-point contact ball bearings to run longer and more reliably while reducing heat, noise, and vibration levels. The bearings are made from spotless steel with a unique SKF heat treatment to provide outstanding strength, stiffness, and wear-resistance. An improved brass cage is lighter, to reduce inertia forces. It also provides better ball guidance.

A PEEK cage, which combines the advantages of lightweight plastic with the durability and performance of a brass cage is also available. A shoulder recess on the inner ring provides additional lubrication improvements, and a redesigned raceway shoulder transition makes the bearings capable of carrying increased thrust loads.

SKF Explorer four-point contact ball bearings, which are manufactured to P6 dimensional and running accuracy, have a 35° contact angle.
