Angular Contact Bearings

Description

Structure and Features
• Raceway Design: The raceways of the inner and outer rings are arranged at an angle relative to the bearing’s centerline — typically 15°, 25°, or 40° contact angles. A larger contact angle increases the bearing’s ability to withstand axial loads.
• Load Capacity: Capable of supporting combined radial and single-direction axial loads. When paired, they can handle bi-directional axial loads.
• Mounting Configurations: Common arrangements include back-to-back (DB), face-to-face (DF), and tandem (DT) setups, chosen based on stiffness, axial balance, or load requirements.
• High Precision: Timken offers P4 and P2 accuracy grades for high-precision angular contact bearings, ideal for spindles, aerospace, and precision instruments.
