Double Row Angular Contact Thrust Ball Bearings 234408M SP 234408BMP4 234408

Double Row Angular Contact Thrust Ball Bearings 234408M SP 234408BMP4 ?234408

Details:

Angular contact ball bearings are able to support radial load and axial load.As single row angular contact ball bearings can only suport axial load in single direction,matched bearing,mounting is often adopted to them.As matched pair of bbearings,preload for them is convenient.Retainers are made of brass,synthetic resins or others subject to individual bearing features and application condition.
