Double row angular contact ball bearing Double row angular contact ball bearing Applicati on: Mine machine, port hoisting machine, port transfer equipment, on shore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generation, other construction and industry machines or equipment. Dimension D: 10-1700 mm D: 30-1900mm H: 9-218mm Material: Bearing steel, chrome steel, stainless steel Designs includes: @ Includes three large categories: Single-row angular, three-point, four-point and double-row angular contact 1) Single-row angular ball bearings accommodate radial loads, acting simultaneously with relative great axial load in one direction 2) For axial load accommodation in both directions and bearings are arranged in pairs 3) Series: 70xx, 72xx, 73xx, 74xx, 79xx, 30xx, 32xx, 33xx, 38xx, 39xx, non-standard series and inch series 4) Contact angle classified as C (15-degree), AC (25-degree) and B (40-degree) 5) Mounting ways have DT tandem, DF face-to-face, dB back-to-back, TBT two tandem and back-to-back, G universal 6) Requires significantly less space in an axial direction than double-row designs 7) Double-row angular contact ball bearings principally correspond to matched pair of single-row angular contact ball bearings 8) Nylon 66 cage, but pressed steel cage can be supplied for some types Notes: We can offer you more choices just if you kindly give us chance to quote (As old sayings-Buyer want more choice and Seller want more buyers) We have ourself brand and we also are the authorized distributor for SKF, TIMKEN, INA, NSK, IKO, NACHI, KOYO, ASAHI, we can offer C/O Other angular contact ball bearing information: An angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race. Ceramics such as silicon nitride are now regularly used in such applications due to their low density (40% of steel). These materials significantly reduce centrifugal force and function well in high temperature environments. They also tend to wear in a similar way to bearing steel_rather than cracking or shattering like glass or porcelain. Most bicycles use angular-contact bearings in the headsets because the forces on these bearings are in both the radial and axial direction.
