Description:
Angular contact ball bearings have two types.
Double row angular contact ball bearing can bear radial and axial load joint load, limit shaft on both sides of the axial displacement.
Single row angular contact ball bearing only carry a direction of the axial load, when in bear radial load, can cause additional axial force must be applied to the corresponding reverse load, therefore, the bearings are generally used in pairs.
Application:
Single-row angular contact ball bearings can be used in machine tool spindles, high-frequency motors, gas turbines, small automobile front wheels, differential pinion shafts.
Double-row angular contact ball bearings can be used in oil pumps, Roots blowers, air compressors, fuel injection pumps, printing machinery.
Packaging:
1. Industrial packaging: plastic bag/plastic tube + kraft paper + carton + plywood pallets
2. Commercial packing: 1pc/plastic bag + color box + carton + plywood pallets
3. As the clients' requirement
