Prismatic thin-walled bearings is open seven series and five series consisting of sealing , diameter size from 1 inch to 40 inches , the cross-sectional dimensions ranging from 0.1875X0.1875 inches to 1.000X1.000 inches. Open bearings are available in three types : radial contact (L -type ) , angular contact (M type ) , four-point contact (N -type ) . Sealed bearing only two categories: radial contact (L type ) , four-point contact (N -type ) .

The company produces thin-walled bearings and bearing a different standard in thin-walled bearings , each series of cross-sectional dimensions are designed to be fixed, in the same family size is unchanged, it does not change with diameter size increases. Thus , the series is also known as thin-walled bearings and other bearing section of thin-walled , designers can make ordinary parts associated with standardization.

Using a large bore, thin wall bearing a small cross-section of large diameter hollow shaft can be used , such as : air, water pipes , wires can be provided through the hollow shaft to make the design more simple .

Thin section bearings can save space , reduce weight, and significantly reduce friction , and then provide good precision rotation, without affecting the performance and service life of the bearings , the use of thin-walled bearing design can reduce the external dimensions and lower production costs.

In 2006, cross-section , such as thin-walled bearing products won the national Torch Program undertaker , 2008 National Science and Technology Innovation project funding.
