QJ1020Angular Contact Ball Bearing Short Description

QJ1020 bearing, the four-point contact ball bearing is a separable bearing or a set of angular contact ball bearings that can bear bidirectional axial load.


When only the pure axial load acts, the steel ball and the ferrule become two-point contact, which can bear bidirectional axial load. Four-point contact ball bearings can also bear moment loads, and have the functions of single row angular contact ball bearings and double row angular contact ball bearings. Four-point contact ball bearings can only ensure normal operation when they form two-point contact.

QJ1020 Four Point Angular Contact Ball Bearing Features

The four-point contact ball bearing is a separable structure, and a single bearing can replace the angular contact ball bearing with the front combination or the back combination.


It can bear radial load and bidirectional axial load and can limit the axial displacement in two directions, but it occupies less axial space than the current specification double row angular contact ball bearing.


Compared with other ball bearings, four-point contact ball bearings have a smaller axial clearance and a higher limit speed when the radial clearance is the same.


Four-point contact ball bearings are suitable for bearing pure axial loads or combined axial and radial loads based on axial loads. Due to the double-half inner ring (or outer ring), the number of balls is increased and the bearing capacity is larger.


Under normal working conditions, when this type of bearing bears axial load in any direction, a contact angle can be formed. The steel ball contacts the inner and outer raceways at one point to avoid large sliding friction in the contact area. Therefore, the bearing should not be subjected to radial forces and loads.

QJ1020 Bearing Application

Generally, this kind angular contact ball bearing is suitable for those occasions where there is two-point contact under pure axial load or synthetic load with a large axial load. Four-point contact ball bearings have a high limit speed and are also suitable for those high-speed running occasions.
