CHG products thin section ball bearings include 7 opened series and 5 sealed series，the inner diameter range from 1.000" to 40.000" and the sectional dimension range from 0.1875" × 0.1875" to 1.000" × 1.000"，3 kinds open type thin section bearings are available: Radial contact (type C), Angular contact (type A) and Four-point contact (type X). 2 kinds sealed thin section bearings are available: Radial contact (type C), and Four-point contact (type X). We can provide the products with different internal clearances, contact angles, lubrication modes, cage structures and other properties to meet the needs of most customers. Where the corrosion resistance is required, the bearings produced with the stainless steel 9Cr18 should be preferred, with a convenient and quick delivery. Where there is no any severe pollution, the opened bearings should be preferred; where the cleaning and well lubrication are required, the sealed bearings should be preferred. There are many bearing cage structures for selection, which are used to space evenly the rolling elements and prevent the friction from their mutual contacts. The common cage structures include overall “Crown”, overall circular pockets, wire ring form, teflon spacers, isolation balls and so on.
