Four point contact ball bearings are separable type bearings, can also be called as angular contact ball bearings which can take axial loads in both sides. The inner and outer ring are peach like section. When there's no loads or only radial loads, the steel balls and rings show the four point contact. That's the origins of the name.

Inner Design

CN--Normal radial clearance, Without Suffix.

C3--Radial internal clearance abrov normal.

N2--9q two grooves opened on 180 degree, located in the big outer ring ends.

Besides we can offer other conventional internal and external variations or customized bearings according to customers' need.

• 
• Single Row Angular Contact Ball BearingsSingle row angular contact ball bearings are able to undertake radial and axial loads at the same time, in some circumstances can take only axial loads and run in a high speed. They are made of high quality bearing steel GCr15. Angular contact ball bearings's axial loads capacity increased by the increase of angle. Defination of contact angle αis contact area of axial loads capacity.

• 
• Double Row Angular Contact Ball BearingsBesides, angular contact ball bearings include double row angular contact ball bearings. This type of bearings can take huge radial and axial combine loads and moment loads which mainly are radial loads, it limited axial move in both sides. Mainly used in components which limit two-way axial displacement of shaft and shell. Compare to the single row angular contact ball bearings....

• 
• Large Double Row Angular Contact Ball BearingsLarge double row angular contact ball bearings were originally designed for the axial location of the rolls of finishing mills and wire rolling mills which are supported in cylindrical roller bearings. They are eminently suitable for the high speeds and relatively small axial forces encountered in these applications, but are also suitable for other applications....
