Structural Types and Features of Double Row Angular Contact Ball Bearings

by:JNSN     2021-12-18
Double row angular contact ball bearings are a type of bearing that combines single row angular contact ball bearings back-to-back, and the inner and outer rings are each integrated. It can bear radial load and axial load in two directions. Suitable for fixed ends, usually using copper alloy car cages. As shown in photo 4 and figure 8. Special double row angular contact ball bearings are a type of bearing that combines single row angular contact ball bearings back-to-back or face-to-face, and the inner ring or outer ring is integrated. It can bear radial load and axial load in two directions. Special double row angular contact ball bearings are suitable for fixed ends, usually with copper alloy car-made cages. As shown in Figure 10. Four-point contact ball bearing is a single-row angular contact ball bearing with separate inner and outer rings. The inner ring is divided into two parts in a vertical plane to the central axis. One set of bearings can bear bidirectional axial load. The ball has a contact angle of 35° with the inner and outer rings. This kind of bearing can be interchanged with face-to-face or back-to-back angular contact ball bearings, bearing bidirectional axial loads. Copper alloy car cages are generally used. As shown in Photo 6 and Figure 11. (a) The style of adding a dust cap or sealing ring to the original open product (b) The grease is sealed at the factory, and there is no need to maintain the grease during use (c) The back-to-back combination method (two single-row angular contact balls) Compared with the bearing), the compact design with narrower width (d) has larger radial load capacity and axial load capacity in two directions (e) has the ability to withstand moment load. The point of application is equipped with a sealing ring or a protective ring. Double row angular contact ball bearings with dust cover.
