Thrust ball bearings generally have better centripetal performance, but their load-bearing capacity is smaller than that of thrust roller bearings.The thrust ball bearing adopts a design that can withstand thrust loads during high-speed operation, and is composed of a washer shaped ring with ball ro

There are two types of imported bearings for high-speed wire rolling mills: four row tapered roller bearings and double row cylindrical roller bearings. In general, bearing faults are identified by working temperature. Coarse and medium rolling mills use four row tapered roller bearings, precision r

Thrust roller bearings are used to withstand axial and radial combined loads, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this type of bearing has a lower friction coefficient, higher rotational speed, and has centering performance.Thrust r

The tapered roller bearing belongs to the separated type bearing, and both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types based on the number of rows of installed rollers, such as single row, double row, and four row ta

On railway locomotives and vehicles, the components that are attached to the axle neck to connect the wheelset and bogie frame or two axle car body are referred to as axle boxes. Its function is to transfer the weight and load of the vehicle body to the wheelset, lubricate the axle neck, reduce fric
