Angular contact bearing is a rolling bearing in which the contact point between the steel ball and the inner and outer rings is connected at an angle to the radial direction. Its core feature is that it can withstand both radial and axial loads simultaneously, and the larger the contact angle (15 °, 30 °, 40 °, etc.), the stronger the axial bearing capacity
1. Type and structure
Single row angular contact bearings: can only withstand unidirectional axial loads and need to be installed in pairs (back-to-back, face-to-face, or in series) to counteract additional axial forces
Common models include the 7000 series (such as 7005C, 7010C).
Double row angular contact bearings, such as 5204-2RS and 3200 series, can withstand bidirectional axial loads and are suitable for high-precision scenarios
Four point contact bearing: QJ series, capable of withstanding multi-directional loads
