Angular Contact Bearings

Angular Contact Bearings

A connection with the radial angle of angular contact ball bearing steel ball and the inner and outer ring contact point. Contact angle is generally divided into 15°, 30°, 40°, respectively, with the letter C, A, B said, NSK special production contact angle of 25° of such bearings, with A5 said. Angular contact ball bearings are mainly subjected to large axial load, the greater the contact angle, the greater the load capacity. The retainer material has the steel plate, the brass or the engineering plastic, the forming way has the stamping or the turning, the visual bearing form or the use condition is different and chooses. Other there are combination of angular contact ball bearings, double row angular contact ball bearings and four point contact ball bearings.

  • Description

Bearing Type

Angular contact ball bearings are: type 7000C (∝=15°), type 7000AC (∝=25°) and 7000B (∝=40°) several types. The lock on the outer ring of the bearing, generally can not be separated from the inner and outer rings, can bear radial and axial joint load and a direction of the axial load. The ability to bear axial load is determined by the contact angle, the greater the contact angle, the ability to bear axial load is high. The bearing can limit the axial displacement of the shaft or the outer shell in one direction.

Main Application

Single row angular contact ball bearing spindle, high frequency motor, gas turbine, centrifugal separator, the small car front differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, welding machine, low noise cooling towers, electrical equipment, coating equipment, machine bed plate, arc welding machine.

Double row angular contact ball bearings: pump, blower, air compressor, all kinds of transmission, fuel injection pump, printing machinery, planetary reducer, cycloid reducer, extraction equipment, food packaging machine, electric welding machine, electric iron, square box, gravity type gun, stripping machine, half shaft, test equipment, fine chemical machinery.

Installation Skill

High speed precision angular contact ball bearings, mainly used in the light of the load of high speed rotating occasion, the requirements of high precision bearings, high speed, low temperature and low vibration and a certain life. The supporting member of the high-speed electric main shaft is used in pairs to be installed and used, and is the key matching component of the high speed electric spindle of the inner surface grinder.

Installation Form

Angular contact ball bearings and easy automation selection Daquan can provide selection, installation form of angular contact ball bearings, a series of face to face and back to back, three. (two back-to-back wide end bearing relative) installation, bearing contact angle line along the axis of rotation diffusion direction, bearing angle can increase the radial and axial rigidity, maximum deformation resistance; face to face (two relatively narrow end bearing) installation, bearing contact angle of the rotary axis line towards the direction of its convergence. To the point of less rigidity. Because of the inner ring of the bearing outer ring out, when pressing the outer ring two bearing together, the original gap ring is eliminated, can increase the bearing preload; tandem arrangement (two wide end bearing in one direction) when installing the bearing contact angle and parallel lines in the same direction, the two share the same bearing the direction of the work load. But the use of this form of installation, in order to ensure the stability of the axial installation, two pairs of bearing series must be installed at both ends of the opposite axis.
