Spindle bearings

Spindle bearings are precision angular contact bearings built for high speed and stiffness. They are usually supplied in matched sets (DB, DF, DT) with a specified preload. Send the full number from the old bearings, including the suffixes, so the precision class, contact angle and preload match.

Common types

• Angular contact spindle bearings (15 and 25 degree)
• Matched sets: DB, DF, DT
• Ceramic (hybrid) ball versions
• High-speed sealed versions

Where they’re used
