Thin Section Bearing

Thin section bearings are a family of bearings designed from a limited number of widths and thicknesses (cross sections), with each cross section manufactured in a wide range of bore diameters. Most radial ball bearings are designed so that as the bore size increases, the width and the thickness of the bearing change proportionately. In the case of thin “ Thin section bearings help reduce total cost in a system by allowing for design efficiency over standard bearing sizes. ”section bearings the cross section remains the same as the bore diameter increases. The thin section bearing family is made up of 12 primary cross section sets ranging from 3/16" to 1" and with bore sizes ranging from 1" to over 40". The combination of a large bore diameter in proportion to the small cross section makes these parts appear "thin" in comparison to standard ball bearings. Thin section bearings are made from 52100 chrome steel and 440C stainless steel. They can also be coated with platings like thin dense chrome. Some sizes can be configured with seals or shields. Thin section bearings are also made in one of three different contact styles; radial contact, angular contact, and four point contact. These options, along with several ball and retainer types make for a diverse range of parts even among the limited cross sections of the thin section bearing family.


Thin section bearings offer high accuracy in a low profile design, available in standard stainless or chrome steel, configured as deep groove or angular contact, and with a host of special features.
