Features of double-row angular contact ball bearings

1、Double row angular contact ball bearings are made of super clean steel to extend the service life by up to 80%.

2, Grease technology, made of fine lubricating grease, can extend the life and performance of the double-row angular contact ball bearings.

3、The stability of double row angular contact ball bearing is strong; even under high-speed rotation and growth, it can maintain smooth operation and reliable quality.

4, the contact angle in the bearing is the journal, and the contact surface of the sliding bearing to the circle of the angle is not too big or too small. Double row angular contact ball bearing contact angle opening angle is diverse and can meet the needs of different machinery.

5、Double row angular contact ball bearings are sealed with advanced sealing technology, which can resist pollution even in very harsh environments and ensure the performance is not reduced.

6、Under the right conditions, the bearing friction coefficient is low, and the heat generated by the bearing is reduced, which can give the bearing a more obvious limit speed when grease lubrication. In different environments, more have different degrees of influence; the use of special or other different environments should be fully considered in the impact brought about.

7, after heat treatment, double-row angular contact ball bearings can be in an environment below 150C for continuous operation if the cage uses polyamide material; the cage limits the impact temperature, and the seal requirements will limit sealed bearings. In addition to optimizing the surface quality, the collar material used for the bearing is also subjected to a special heat treatment. This allows the bearing's inner and outer ring raceways to resist solid particles and mixed friction. Due to the reduction of the surface tension of the lubricant, thus making the working life of the grease is increased.

71、Compared with single-row angular contact ball bearings, the outstanding feature of double-row angular contact ball bearings is that they can simultaneously bear the combined radial and axial loads, limiting the axial displacement of both sides of the shaft. The contact angle determines its axial load capacity and increases with the increase of the contact angle.
