Features: 1) Our angular contact ball bearings include three big categories: single row angular contact ball bearings, three-point-contact and four-point-contact ball bearings and double row angular contact ball bearings 2) Single row angular contact ball bearings accommodate radial loads, acting simultaneously with a relative great axial load in one direction 3) For axial load accommodation in both directions, the bearings are arranged in pairs against each other 4) They have series of 70xx, 72xx, 73xx, 74xx, 79xx and inch series 5) Contact angle is classified as C(15°), AC(25°) and B(40°) 6) Mounting ways have DT - Tandem, DF - Face to face, DB - back to back, TBT - two tandem and back to back, G - Universal 7) Three-point-contact and four-point-contact ball bearings are also single row angular contact ball bearings, which require significantly less space in an axial direction than double row designs 8) Double row angular contact ball bearings principally correspond to a matched pair of single row angular contact ball bearings 9) Series available are 30xx, 32xx, 33xx, 38xx, 39xx and non-standard series 10) Most have nylon 66 cage, but pressed steel cage can be supplied for some types
