Luoyang Lirui Bearing Co. Ltd is a professional company engaged in the production of bearings, such as series of thin-wall deep groove ball bearing, angular contact bearing, four-point contact ball bearing.
There are three kinds of structure of thin-wall bearing, such as ARO, CPO, XPO, which are short for thin-wall angular contact series, thin-walled deep groove ball series and thin-wall four-point contact ball series.
We also specialize in the production of American KAYDON substitute precision thin section bearings, and Germany substitute thin section bearings, imported substitute bearings, and Japan NTN substitute precision thin section bearings.
Thin section four-point contact ball bearing is an ideal choice for supporting moment heavy pressure. It successfully satisfies the four points contact between raceway and steel ball in order to support moment load and reversing axial load. Though it can be applied to withstand light load, it cannot completely replace the radial contact ball bearing and angular contact ball bearing when supporting pure radial load.
For these reasons, they can be widely used in all aspects of life. Such as aircraft, aerospace, astronomical instruments and the clamping equipment, food processing equipment, glass production equipment and rotary worktable, machine tools, packaging equipment, medical equipment, optical scanning equipment, radar, satellite communications equipment, textile machinery, robot and semiconductor manufacturing equipment, etc.
Four-point contact ball bearing can bear radial load and two-way axial load.
A single bearing can replace the positive combination or the back combination of angular contact ball bearings.
They apply to pure axial load or synthetic load with larger axial load in it.
Contact Angle (alpha) will be formed when the bearing withstand axial load from any direction, so the ring can always be in contact with the ball in any online points
Main applicable cage: Copper alloy cutting cage
Main use: Aircraft jet engines, gas turbine.
