B70 Angular Contact Ball Bearings B7010C B7010C/HQI High Speed

Angular Contact Ball Bearings:

Angular contact ball bearings ball point of contact with the inner and outer rings and radial connections at an angle. Angular contact ball bearings mainly take large axial load, the contact angle increases, the greater the ability to withstand load. Cage materials are steel, brass or engineering plastics, molding methods are punching or turning, depending on the conditions of the bearing form or by using different selection. There are other combinations of angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.  

Angular contact ball bearings can support radial load and axial load. In high speed work. Larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually take the contact angle of 15 degrees. In the axial force, the contact angle will increase. Single row angular contact ball bearings can withstand axial load in one direction, the radial load, will cause additional axial force. And the only limit shaft or housing in a direction of axial displacement. If paired mounting, making a pair of bearing outer ring is relatively wide side face of wide and narrow side facing the narrow end. This can avoid additional axial force, but also in both directions so that the shaft or housing to limit axial clearance range.
Angular contact ball bearings because of inner and outer ring raceway can be relative displacement on the horizontal axis, so it can bear radial load and axial load - combined load (single row angular contact ball bearings can withstand axial load in one direction, so often used in pairs). Retainers are made of brass, synthetic resins, etc., according to individual bearing features and application conditions.

Angular contact ball bearings: 7000C-type (α = 15 °), 7000AC type (α = 25 °) and 7000B (α = 40 °) of several types.

This kind of bearing outer ring of locking in on the inner and outer rings can not be separated, can be combined radial and axial loads and axial loads in one direction. Axial load capacity determined by the contact angle, the contact angle is large, the ability to withstand high axial loads. This kind of bearing shaft or housing to limit axial displacement in one direction.
