FAG universal spindle bearings are available in the following designs: B, RS and H bearings.

B spindle bearings

• Classical spindle bearing
• With large balls
• Contact angle 15° and 25°
• High load carrying capacity and high rigidity
• For moderate speed level.

RS spindle bearings

• With large balls
• Contact angle 20°
• Suitable for high to very high speeds due to bearing internal design with optimised friction
• Kinematic insensitivity to tilting
• High load carrying capacity especially under combined axial and radial load
• Particularly suitable for high speed milling spindles and motor spindles.

H spindle bearings (high speed design)

• With small balls
• Contact angle 15° and 25°
• Suitable for very high speeds due to internal design with optimised friction and very low centrifugal forces on the rolling elements
• High rigidity at high speeds
• Particularly suitable for very high speed spindles and grinding spindles.

Design of bearing types

The bearings are available with steel and ceramic balls and in an open, sealed and DLR design.

FAG H spindle bearings are also available with Cronidur rings.
