SI Bearing provides the single row, double rows, four-point angular contact ball bearing 7000 7200 7300 32XX 33XX QJ2XX QJ3XX, sealed or open type, steel, brass, nylon cage available.
Angular contact bearings are suitable for applications that bear both radial and axial directions, and can also be used to bear pure axial loads, allowing operation at higher speeds.
The single row angular contact bearing structure has two types: separable and non-separable. It can only bear axial load in one direction. In many applications, it is used in pairs or multiple configurations.
The contact angles of standard products are 15°, 30°, and 40°. The larger the contact angle, the greater the axial load bearing capacity. The smaller the contact angle, the better the high-speed rotation.
The cage has different structural forms such as steel stamping, glass fiber reinforced nylon 66 and solid cage. Solid cages are mostly made of brass, bronze, various light alloys, or phenolic laminated cloth tubes(Bakelite) and other manufacturing.Information of SI high-speed angular contact ball bearing :Name | angular contact bearing |
