ZYS Thin Section Four Point Contact Ball Bearings QJF220 for Print
Machinery The four-point contact ball
bearing is the kind of bearing which can be separable. The 0000
type has a double semi-inner ring, and the OJ0000 type has a double
semi-outer ring, and the contact angle is 35°. When there is pure
radial load or no load, the steel ball and the ring are in
four-point contact; under the action of pure axial load, the steel
ball and the ring are in two-point contact and can withstand
bidirectional axial load. This type of bearing can also withstand
moment loads and combine the functions of single row and double row
angular contact ball bearings. This kind of bearing can only
guarantee normal operation when two-points contact is formed.
