That why we are so good: same quality as imported product but 1/3 price

3.four point angular contact ball bearing technical characteristics: 

1.)The four point contact ball bearings can be fitted within the single row angular contact ball bearings.
2.)Four point contact bearings are suitable to support high axial loads in both directions and they can also support some radial load if this does not exceed a certain value relative to the axial load applied.
3.)They consist of a solid outer ring and split inner ring into two symmetrical parts.
4.)Thanks to its design with a split inner ring game,these allow the incorporation of larger and more number of balls,providing a higher load capacity,in less space than a doule row thrust bearings
