 Angular Contanct Ball Bearing Detail

1.Angular Contact Ball Bearing Description:

Angular contact ball bearing can withstand radial load and axial load simultaneously, as well as the pure axle loads. They have higher limit speed. High precision and high speed bearings usually take 15 degrees contact Angle. The contact angle decide the capacity of axial load. Retainers are made of brass, synthetic resins or others subject to individual bearing features and application conditions.
Single-row angular contact ball bearings can accommodate axial load in one direction, if enduring radial load, it will raise additional axial force. And only limited axial displacement of the shaft or housing in one direction. The contact angle of angular contact ball bearings is 40, so you can afford a large axial load. Design of angular contact ball bearing is non-separable, shoulder height on both sides of the inners and outer rings are different. In order to increase the bearing load capacity, lower one side of the shoulder, so that the bearing can be mounted into more balls.

2.Angular Contact Ball Bearing Classification :

(1) A type 90mm diameter less than or equal to the standard design of the bearing. No ball gap, so it can withstand the equivalent of two-way axial load. The use of lightweight glass fiber reinforced nylon 66 cage, the bearing temperature rise is very small.
(2) B type 90mm diameter greater than the standard design of the bearing. Side of the ball gap, with steel stamping cage or brass cage.
(3) C genera enhanced structure, the side with filling slots, you can install more of the ball, so the higher carrying capacity.
(4) on both sides with dust cover type and sides with a ring type A and C design design double row angular contact ball bearings can be on both sides with a dust cover (non-contact) or seals (contact ). Sealed bearings are filled with rust lithium grease, operating temperature is generally -30 ~ + 110 ℃. Without re-lubrication during use, it should not be heated before installation, should not be cleaned.
