CHG provides screw bearings as follows：
7602, 7603 series , TAC series
Ball guide polyamide resin cage (Tnl)
Contact sealing ring ( 2RS ) at both end faces.
Screw Bearing With Sealing
The features of CHG screw bearing include 60° big contact angle, increasing ball number and higher axial rigidity. Based on the 76 series, the contact type sealing rings are added on the two end faces , impurities are prevented into the bearing and the bearing service life is prolonged.
