When designing bearings, competing requirements must be considered. For angular contact thrust ball bearings intended for use in screw drives, the most important factor is to provide a high degree of bearing stiffness while keeping the bearing friction at the lowest level.

A further requirement is the ability to cope with high speeds and rapid accelerations. Maintaining an adequate load-carrying cap-acity and providing high accuracy is typically taken for granted.

The new assortment of super-precision single direction angular contact thrust ball bearings for screw drives come with a combination of visible and invisible features:

• a fine-tuned osculation
• a 62° contact angle
• a ground transition between raceway and shoulder
• a robust cage
• a unique heat treatment
• very clean bearing steel
• tightened manufacturing tolerances
• matchable execution – bearing arrangement with up to four bearings per set
• sealed execution for all bearing sizes.
