Four-point contact ball bearings
- Description of the four-point contact ball bearing:
-- The normal structure is that the inner ring is divided equally in axial direction with contact angle, they can applicable to carry the pure load or the combined load with the majority of axial load.
-- Single bearing can carry axial load in double directions and radial load to a certain degree. Depending on the different direction of axial load, rings always contact balls on the two points at any line on left or right.
-- These bearings are mainly applied in jet plane or gas turbines.
-- When using four point contact ball bearings, analysis should be done load and son on.
-- The four point contact ball bearing's features compact in design, and light in weight. The balls contact with the circular race at four points, via which the axial force, radial force and resulant moment may be used for slewing conveyors, welding AMS and positioners light, medium duty cranes, excavetors and other engineering machine.
