Structural Type and Characteristics of NSK Double Row Angular Contact Ball Bearings
NSK double row angular contact ball bearings are single row angular contact ball bearings combined back to back, and the inner and outer rings are integrated into one bearing style. It can withstand radial loads and axial loads in both directions. Suitable for fixed ends, usually with copper alloy machined cages. As shown in photos 4 and 8. The special double row angular contact ball bearing is a bearing style in which the single row angular contact ball bearing is combined back-to-back or face-to-face, and the inner ring or the outer ring is integrated. It can withstand radial loads and axial loads in both directions. Special double row angular contact ball bearings are suitable for fixed ends, usually with copper alloy machined 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. The ball and the inner and outer rings have a contact angle of 35. This bearing can be interchanged with face-to-face or back-to-back angular contact ball bearings to withstand bidirectional axial loads. Generally, a copper alloy car cage is used. As shown in Photo 6 and Figure 11. (a) The original open type product with dust cover or sealing ring added (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 bearings), a compact design with a narrower width (d) has a larger radial load capacity and axial load capacity in both directions (e) has the ability to withstand moment loads.
