What Are Angular Contact Ball Bearings?

Angular Contact Ball Bearings are a type of rolling element bearing designed to accommodate combined loads. Unlike standard radial ball bearings, Angular Contact Bearings have an inner and outer raceway that are displaced relative to each other in the direction of the bearing axis.

Features of Angular Contact Bearings

• Tilted Raceways: The ability to support axial loads in one direction.
• Preloading Capabilities: Ensures minimal play between bearings for improved performance.
• Directional Limitations: They are designed to operate effectively under specific load conditions, making their application critical.
