The difference between Type A - thin section angular contact ball bearings and standard angular contact ball bearings is that the section size is designed to be single, and the section bearing and standard size are unchanged in a series. It does not increase with pore size. Therefore, this angular contact open thin section bearing is called a constant-section thin-wall bearing. By using the same series of thin-section bearings throughout a products line, the designer could standardize on common components.
Type A - Thin section angular contact ball bearings bore diameter ranges from 1 inch to 40 inch, Cross section ranges from 0.1875 × 0.1875 inch to 1.000 × 1.000 inch.
Thin section bearings
are designed to save space, decrease the overall weight, dramatically reduce friction, and provide excellent running accuracy. The special features of the thin section bearings enable customers to downsize their design and cut manufacturing costs without sacrificing bearing performance or life.
