We Provide Precision Miniature angular contact Ball Bearing

Miniature angular contact ball bearing refer to the public system, the outer diameter is less than 9mm; the British series, the outer diameter is less than 9.525mm.Generally used for equipment with high precision requirements for the main axis, air compressors.

Single -rowed miniature angular contact ball bearing can only withstand axial loads in one direction. When withdrawing the radial load, it will cause additional axial force. And can only limit the axis orientation of a shaft or shell in one direction. The contact angle of the corner contact is 40 degrees, so it can withstand a large axial load. The angle contact ball bearings are non -separated design, and the shoulders on both sides of the inner and outer ring are different. In order to improve the load capacity of the bearings, one shoulder will be processed lower, so that the bearings can be installed into more steel balls.

Dowble-rowed miniature angular contact ball bearings can withstand large radial loads, which are mainly radial and axial combined loads and torque loads, and restrict the axial displacement of the two aspects of the shaft. It is mainly used to limit the tilt of the double -column angle contact between the double -column angle in the parts of the two -way axis displacement of the shaft and the shell. Allowing corners depends on the internal gaps, bearing size, internal design, and force and torque acting on the bearing, and the maximum allowed tilt corner should ensure that there is no high additional stress in the bearing. If there is an inclined angle between the inner and outer circles of the bearing, it will affect the life of the bearings, and at the same time cause the bearing operation accuracy to decrease and increase the noise.

Double-row miniature angular contact ball bearing generally use nylon holders or brass entities. It should be noted that although the bearings can withstand two -way axial load, if there is a gap in the ball on one side, be careful not to let the main axial load be on the side of the gap with a gap. When using bearing, you should pay attention to the main load on one side of the gap without the ball.

paired dual miniature angular contact ball bearings:
If it is installed with double couplet, the outer ring of a pair of bearing is opposed, that is, the wide end faces the wide end surface and the narrow end is facing the narrow end surface. In this way, the additional axial force can be avoided, and the shaft or shell can be limited within the axial gap in two directions.
