The contact angle of thrust angle contact ball bearings is generally 60 °. The commonly used thrust angle contact ball bearings are generally bi-directional thrust angle contact ball bearings, mainly used in precision machine tool spindles. They are generally used in conjunction with double row cylindrical roller bearings and can withstand bi-directional axial loads. They have advantages such as high accuracy, good rigidity, low temperature rise, high speed, and easy assembly and disassembly.
