Nsk 7218bm angular contact ball bearing

Nsk 7218bm angular contact ball bearing 90*160*30 Specifications: Type: angular contact ball bearing Lubrication: oil or grease Dimensions: 90mm x 160mm x 30mm/metric Id (inner diameter)/bore: 90mm Od (outer diameter): 160mm Width/height/thickness: 30mm Dynamic load rating cr: 103kn Static load rating cor: 88kn Limiting speed: Grease lubrication: 3, 200 rpm Oil lubrication: 4, 300 rpm Features: angular contact bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them as matched parts of bearings, preload for them is more convenient. Retainers are made of brass, synthetic resins or others subject according to individual bearing features and application conditions. 1) load capacities are higher than deep groove ball bearings of same dimensions; 2) used for bearing radial-axial combined loads or pure thrust loads; 3) low operating friction and high limiting speed. Angular contact ball bearing include: 1) single row angular contact ball bearing 2) matched angular contact ball bearing 3) double row angular contact ball bearing 4) four-point contact ball bearing Applications¡êoangular contact ball bearing is mainly applied on high speed, high precision and little axial load occasions, such as airplane engine main shaft, machine tool main shaft and main shafts of other high speed precision machine. It can also be applied on high frequency motor, steam turbine, oil pump, air compressor and printing machine etc. It is one of the bearings most widely used in machinery industry.
