QJ series four point contact ball bearings

The QJ series four point contact ball bearing is a special form of deep groove ball bearing, with two contact angles and four contact points on the inner and outer rings, which can withstand bidirectional radial and axial forces. Four point contact ball bearings are often used as axial bearings in combination with a radial bearing. Four point contact ball bearings are divided into two types: sealed and unsealed, and are usually used in mechanical equipment, robots, and precision instruments.
