Four-point Angular Contact Ball Bearing
WBJF

█ The main features of angular contact ball:

Angular contact ball bearings have a high limit rotation speed, they can bear radial load and axial load at the same time, and they can also bear pure axial load. The axial load capacity is determined by the contact angle and increases with the contact angle.

The main structures are single row angular contact ball bearings, four-point angular contact ball bearings, double row angular contact ball bearings, and angular contact ball bearings in pairs.

Four-point angular contact ball bearing QJ0000 type and QJF0000 type, Jinfeng bearing patented structure retainer. The cage is characterized by good ball loading and ball lock. Bearings using this cage are divided by YA8 after the model number.

Jinfeng bearing product series: 7000,7200,7300,7400,4000,4900,QJ1000,QJ200,QJ300,QJF1000,QJF200,QJF300

█ Applied industries: machine tool spindles, electromechanical equipment, printing machinery, speed reducers, blowers, compressors, etc.
