Equal cross-section thin-walled bearing refers to the bearing in the radial and axial direction of the two cross-sectional size is equal, and the size is relatively thin, and the normal bearing these two dimensions are not equal, so a separate category called equal cross-section thin-walled bearing, mainly used in size restrictions require bearing size cross-section very small to use the occasion.

Equal section thin walled ball bearings by seven open series and five sealed series, bore diameter from 1 inch to 40 inches, cross-sectional size range from 0.1875X0.1875 inches to 1.000X1.000 inches, three types: deep groove ball type, angular contact type, four-point contact type, material Gcr15 and stainless steel two choices. The thin-walled sleeve bearings are available as deep groove ball bearings (C), four point contact bearings (X) and angular contact ball bearings (A). All of these designs are available in different series. The series then depend on the size of the cross-section. The balls are matched to the series. Deep groove ball bearings can support axial loads as well as radial loads in both directions. Four point contact bearings can support bi-directional and are widely used in industrial robots, variable speed devices, precision instruments, imaging equipment, office equipment, medical, radar, optical equipment, etc.
