Bearing 6311 N

6311N is a reliable open-type radial single-row ball bearing with a special groove for a retaining ring on the outer cage, which is a complete analogue of the 50311 marking according to GOST. It is designed for units where rigid axial fixation of the bearing in the housing is required while maintaining the ability to withstand significant radial loads. The key feature of the 6311-N modification is the presence of a locking groove, which allows you to securely fix the bearing and prevent its axial displacement during operation. The main technical characteristics of the bearing: inner diameter 55 mm, outer diameter 120 mm, width 29 mm, size 55x120x29. This size is widely used in automotive engineering: on KamAZ vehicles in the center differential and cardan shafts; on KrAZ in the front axle and cardan transmission; on URAL vehicles in the transfer case. In the agricultural sector, the bearing is used on MTZ, DT-75, T-150 and KhTZ tractors in gearboxes, power take-off shafts and drive pulleys, as well as on Yenisei combines and KPS-5G mowers. Since the model is made in an open version with a groove, it requires regular lubrication in accordance with the equipment regulations. To ensure correct installation and long-term operation of the unit, if in doubt, it is recommended to use the help of a qualified specialist.
