Features: 1) As single row angular contact ball bearings can only support axial load in single direction, can sustain radial, axial or moment loads, they always used low operating friction and high limiting speed, matched bearing mounting is often adopted as matched parts of bearings, preload is more convenient 2) This kind of bearings are designed to support combined radial and thrust loads or heavy loads depending on the contact magnitude. The bearing has large contact angles can support heavier thrust loads 3) They are suitable for a wide range for a wide range of applications including high speed machine tool spindles and centrifugal machines 4) Retainers are made of brass, synthetic resin or others subject to individual bearing features and application conditions 5) Models available: 7000ACD/DB, 7000ACD/DF, 7000ACD/DT, 7000CD, 7000ACD, 7200BFP and 7300BEP
