Advantage of 51118 BearingApplication scope of thrust ball bearing:It is only applicable to the parts bearing one side of axial load and low speed, such as crane hook, vertical water pump, vertical centrifuge, Jack, low-speed reducer, etc.The shaft ring, seat ring and rolling element of the bearing are separated and can be installed and disassembled separately.TypeIn addition, the bearing can bear axial load, but can not bear radial load.Composition of thrust ball bearing: the thrust ball bearing is composed of seat ring, shaft ring and steel ball cage assembly.

The main features of rotary support bearings include high bearing capacity, fast speed, small friction, wear resistance, simple structure, easy installation and so on. It can withstand large axial and radial loads, while having high rigidity and accuracy, suitable for high-speed rotation and precision positioning requirements. Different types of rotary support bearings have differences in structural form and working principle, such as four-point contact ball type, two-way thrust ball type, cross roller type, tapered roller type and so on.

The series of products with flanges on the outer wheel make the axial positioning easy; The bearing seat is no longer needed and becomes more economical. In order to obtain low friction torque, high rigidity and good rotation accuracy of bearings, steel balls with small outer diameter are used. The use of hollow shafts ensures lightweight and wiring spaceThe biggest feature is that the flange and the bearing are integrated.

Railway bearings play a key role in the railway transportation system, mainly in the following aspects:1. Bear and transfer loadsRailway bearings can withstand the axle load of the train, and ensure the stability of the track during the operation of the train by distributing the load pressure.
