angular contact ball bearing Design features: angular contact ball bearings in the inner and outer rings on the raceway, and the internal and external circles for the relative displacement axial bearing. This means that the design of the bearing ring compound is used to bear load, the radial and axial load load at the same time role. LHB angular contact ball bearings in a wide range of design and size of production, commonly used types of single row, double row angular contact bearings and sealed double angular contact ball bearings and four point contact ball bearings. We can produce the diameter from 10mm~240mm LHB single row angular contact ball bearings. 10mm~110mm LHB double row angular contact ball bearings ,sealed double row angular contact ball bearings and four point contact ball bearings etc,Following is the internal structure of LHB different product descriptions. A 30° contact angle AC 25° contact angle B 40° contact angle CA Bearing for universal matching. Two bearings arranged back-to-back or face-to-face will have an axial internal clearance smaller than Normal (CB) before mounting CB (CB)Bearing for universal matching. Two bearings arranged back-to-back or face-to-face willl have a Normal axial internal clearance before mounting CC Bearing for universal matching.
