The Four-Point Contact Ball Bearings are separable bearings, typically available in two structures: QJ 0000 (with two half inner rings and a complete outer ring);  QJF 0000 (with two half outer rings a complete inner ring).Their contact angle are both 35°. When carrying pure radial loads, each ball contacts with rings are four point, and they are two point contact under pure axial loads. The bearings can carry axial loads in two directions and certain moment loads, and have the features of single row and double row angular contact ball bearings. They only can work normally in high speed when two point contact is formed.

All the bearings we are offering are direct factory price, fast delivery, perfect quality. For more bearings, please contact us by e-mail, wechat , whatsapp or skype.
