  Kaydon thin wall bearing

  Kaydon's Reali-Slim ® thin-walled bearings are known around the world for their space and weight savings. Since 1941, the precision and reliability of the product can be fully qualified even in the very harsh occasions such as military industry and aerospace.

  Because the modern concept of simplification, miniaturization, lightweight and compactness has been deeply involved in the design of rotating equipment, in order to meet the needs of customers, Reali-Slim ® bearing is designed as a fully hardened, thin section anti friction bearing. Kaydon Thin-walled bearing solves the size / weight problems of traditional bearings, shafts and bearing pedestals, greatly reducing the design weight of the equipment.

  In addition to the ordinary environment, the Reali-Slim series thin-walled bearings of kaydon company are also suitable for harsh and corrosive environment. Dimensions from 1 "to 40" or 20 mm to 360 mm bearing bore and 3 / 16 "to 1" cross section are available. Kaydon thin-walled bearings can be provided in both English and metric sizes. Reali-Slim series can provide open, sealed and stainless steel bearings. In addition, ultra-slim series can provide ultra light thin-walled bearings. The service life of kaydon's Thin-walled bearing is more than 3.5 times that of other imitated brands.

  All products manufactured by kaydon company can provide all kinds of precision from abec1f (P0) to abec7f (P4) to meet different customer needs.
