First understand the thin-walled bearings of equal section: thin-walled ferrule bearings have high precision, very quiet and strong carrying capacity. These ball bearings are available in three designs and are extremely small and mostly square in cross section. In these series, even with larger shaft diameters and bearing bores, the cross section remains the same. These bearings are therefore referred to as equal sections.
The equal-section thin-wall ball bearing retainer is a precision non-standard thin-walled ball bearing retainer consisting of seven open series and five sealed series, with inner diameters ranging from 1 inch to 40 inches, and cross-section sizes ranging from 0.1875X to 0.1875 inches. To 1.000X 1.000 inches.
Three types: deep groove ball type (C), angular contact type (E), four point contact type (X).
Materials are copper, stainless steel, alloy steel, etc.
The products are mainly used in: robot joint bearings, aerospace high-precision thin-wall bearings and large-scale bearings for wind turbines, etc., which require high-precision and small space.
