Thin-Section Ball Bearing

Thin-section bearings are a series of bearings designed with limited widths and thicknesses (cross-sections), and each cross-section has a wide range of bore diameters. Most radial ball bearings are designed as the bore diameter increases, the width and thickness of the bearing change proportionally. Thin-section bearings are designed higher efficiency compared to standard bearing sizes, thereby helping to reduce the overall cost of the system. “The cross-section of thin-section bearings remains the same while the bore diameter increases. The thin-section bearing series consists of 12 main cross-section groups, ranging from 3/16″ to 1″, and bore diameters from 1″ to more than 40”.  Thin-section bearings are made of 52100 bearing steel or stainless steel material. They can also be plated with chromium. These sizes can be equipped with seals or shields. Thin-section bearings are also made with one of three different contact methods; radial contact, angular contact and four-point contact. These options and a variety of ball and cage types constitute a variety of parts, even when the cross-section of the thin-section bearing series is limited.
