15*35*11 Angular contact ball bearing7202 B C AC

Angular contact ball bearing7202 B/AC/CDimension :15*35*11Once ordered, please inform me which type you need? B/AC/C.... thanks.Angular contact ball bearings mainly bear larger unidirectional axial loads. The greater the contact angle, the greater the load carrying capacity. The material of the cage is steel plate, bra or engineering plastic, and the forming method is stamping or turning. It is selected according to the bearing form or use conditions. Others have combined angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.Angular contact ball bearings can bear both radial and axial loads. Can work at a higher speed. The greater the contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Single-row angular contact ball bearings can only withstand axial loads in one direction, which will cause additional axial forces when subjected to radial loads. And can only limit the axial dispment of the shaft or housing in one direction. If it is installed in pairs, the outer rings of a pair of bearings are opposed, that is, the wide end faces the wide end face, and the narrow end faces the narrow end face. In this way, additional axial forces can be avoided, and the shaft or housing can be restricted to the axial clearance range in both directions.Angular contact ball bearings have a relative dispment on the horizontal axis of the raceway of the inner and outer rings, so they can bear radial load and axial load at the same time-combined load (single row angular contact ball bearings can only bear axial load in one direction, Therefore, it is generally used to install in pairs). The material of the cage is bra, synthetic resin, etc., and it is distinguished according to the bearing form and use conditions.Type7000C type (∝ = 15 °), 7000AC type (∝ = 25 °) and 7000B (∝ = 40 °) The outer ring of the bearing of this type of bearing is generally not separated, and can bear radial and axial Combined load and axial load in one direction. The ability to bear the axial load is determined by the contact angle. If the contact angle is large, the ability to bear the axial load is high. This type of bearing can limit the axial dispment of the shaft or housing in one direction.l Single row: 78XX, 79XX, 70XX, 72XX, 73XX, 74XX2 Miniature: 70X3 Double row: 52XX, 53XX, 32XX, 33XX, LD57, LD584 Four-point contact: QJ2XX, QJ3XX
