  • New bearings for high-speed applications | Evolution

    2018-4-13 · In applications with high demands on axial stiffness, such as machine tool screw drives, angular contact ball bearings with larger contact angles (e.g., 62°) are often used. For bearings in high-speed applications with moderate axial loads a smaller contact angle (e.g., 15° or 25°) is preferred.
