Thin section bearings have high precision, low noise and strong load capacity. Most thin section are extremely small and square in cross section. Meanwhile, in their all series, the cross section remains the same even with larger shaft diameters and bearing bores. Therefore, these bearings are referred to as equal sections.

The equal-section thin-wall ball bearings consist of seven open series and five sealed series, with inner diameters ranging from 1 inch to 40 inches, and cross-section sizes ranging from 0.1875X0.1875 inches to 1.000X 1.000 inches. It has three types: deep groove ball type (C), angular contact type (E), four point contact type (X). Materials are copper, stainless steel, alloy steel, etc.

Thin section ball bearings are mainly used in: Robot, wind turbines, Aerospace and defense, Astronomy instrumentation, Optical scanning equipment, Food processing equipment, Glassworking equipment, Packaging equipment, Medical systems and medical devices, Tire making equipment, Machine tools, etc., which require high-precision and small space.
