INA CSEA055-HLE, Angular contact ball bearing, Thin section bearing CSEA, brass sheet metal cage. INA CSEA055-HLE have very small cross-sections relative to their diameters. This allows designs with smaller design envelope and lower mass, while achieving high rigidity and running accuracy.

INA CSEA055-HLE angular contact ball bearings (type E) can be filled with an increasednumber of balls and have a nominal contact angle of α = 30°. They cansupport considerably higher radial loads than deep groove ball bearings orfour point contact bearings and can support axial loads in one direction.
