Railway bearing plays an important part in industry field. Railway transportation is a high-speed development industry, bearing applications in the railway production and application industry is indispensable. So bearing must have high bearing capacity and safety performance.
Railway roller bearing applies in railway. Axle bearing Railway wheel vehicle axle system adopts different structural design due to different application conditions. The locomotive and passenger train have axle boxes, and the bearings are connected to the bogie through the axle boxes. There is no axle box for train wagon, and the bearings connect with the side frames of the bogies through bearing saddle. The bearing bears the impact load between the wheelset and the bogie frame, and also bears the axial load generated by the turning of the vehicle. The wheel shaft bearing structure includes cylindrical roller bearing, cylindrical roller bearing unit, tapered roller bearing and tapered roller bearing unit.
The running speed of the bearing is above 200km/h, which requires bearing to have high bearing capacity and safety performance.
Because the double row tapered roller bearing has a better sealing structure. Adjust its clearance before installation, this type of bearing has widely use in high-speed iron bearings.
Locomotive bearing wheel and axle system adopts different structures due to different application conditions. Locomotive and bus have axle boxes, and the bearings connect with the bogie through the axle boxes. Generally, cylindrical roller bearings are common bearing for locomotive.
Wheelset bearings generally use cylindrical roller bearings.
Generally, double-row cylindrical bearings with sealing devices on both sides. Two paired single-row cylindrical roller bearings with sealing devices on one side are preloaded with grease.
