Angular Contact Bearing

Angular contact ball bearings steel ball inside and outside the ring connection of the point of contact with the radial direction at an angle. The contact angle is generally divided into 15 °, 30 °, 40 °, respectively with the letter C, A, B said, NSK special production of these bearings with a contact angle of 25 °, A5. Angular contact ball bearings mainly bear a greater one-way axial load, the greater the contact angle, the greater the ability to withstand load. Cage material steel, brass or engineering plastic molding the stamping or turning, depending on the bearing form or by using different selection conditions. There are other combinations of , double row angular contact ball bearings and four-point contact ball bearings.
Angular contact ball bearings can support radial load and axial load. Able to work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. High-precision and usually take the contact angle of 15 degrees. Axial force, the contact angle will increase. Single row angular contact ball bearings can withstand a direction axial load, radial load, will cause additional axial force. And the only limit the axial displacement of the shaft or housing in one direction. If paired installation, 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, and the shaft or housing to limit axial clearance in both directions. Angular contact ball bearings because of the raceways of the inner and outer rings relative displacement on the horizontal axis, so it can support radial load and axial load - combined load (single row angular contact ball bearings can only support a single direction axial load, therefore often used is generally installed in pairs). Retainers made of brass, synthetic resins, etc., depending on the bearing features and application conditions distinguish.
Angular contact ball bearings 7000C, 7000AC and 7000B are several types. This kind of bearing locking in the outer ring, inner and outer ring can not be separated, can withstand radial and axial combined load of the direction of axial load. Axial load capacity is decided by the contact angle, the contact angle is subjected to high axial load capacity. This kind of bearing can limit the axial displacement of the shaft or housing in one direction.
Single row angular contact can withstand a direction axial load, radial load, will cause additional axial force. And the only limit the axial displacement of the shaft or housing in one direction. If paired installation, 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, and the shaft or housing to limit axial clearance in both directions.
