Angle contact ball bearing are: 7000C type (∝ = 15 °), 7000AC type (∝ = 25 °) and 7000B (∝ = 40 °) several types. The bearing of the gate on the outer race, generally can't be separated from internal and external circle, can bear radial and axial load and a direction combination of the axial load. Axial load capacity by contact Angle is decided, contact Angle is, the greater the axial load capacity high. The bearing can limit shaft or shell in a direction of the axial displacement. Contact ball bearing limit rotational speed higher, can both radial load and axial load, it also can be subject to pure axial load, its axial load capacity by the contact Angle is decided on the contact Angle and the increase of increase.
Single Angle contact ball bearing
Single Angle contact ball bearing can only take a direction of axial load, when in bear radial load, can cause additional axial force must be shi to the corresponding reverse load, therefore, the bearings are generally used in pairs. Double row angular contact ball bearing can bear larger in radial direction load primarily radial, axial two-way combined load and torque load, it can restrict shaft or shell to bi-directional displacement, contact Angle for 30 degrees
