QJBY Bearing application of Railways

Railway transportation is a rapidly developing industry. QJBY BEARING are also indispensable in the railway production and application industry. Bearings used in the railway industry must have high carrying capacity and safety performance.

Railway bearing application railway, wheel axle bearing railway locomotive, and rolling stock wheel axle system adopt different structural designs due to other application conditions. Locomotives and passenger cars have axle boxes, and the bearings are connected to the bogie through the axle box. Railway freight cars have no axle boxes, and the approaches are connected through the saddle.

The bogie side frame is attached. QJBY BEARING bears the impact load generated between the wheelset and the bogie frame and also carries the axial load generated by the vehicle turning. The wheel bearing structure includes cylindrical roller bearings, cylindrical roller bearing units, tapered roller bearings, and tapered roller bearing units.

Each type of manufacturing equipment is different, so it is essential to find suitable bearing products for your railways, high-speed trains, and other railway equipment. We can help you find the best bearings for your application so that they can operate efficiently. 

With iron Close cooperation process between road vehicle manufacturers and operators, We give the best for each bearing application Configuration scheme. Our products include axle box bearings and Axle box body, used for traction motor, gearbox, vehicle connection Connecting device and pendulum technology bearings and their parts, too—all series such as bearings for doors and sliding walls. Bearings used in the railway industry must have high load carrying capacity, Power, and safety performance.

Bearings for high-speed rail

  The operating speed of the bearing is above 200km/h, which requires the approach to have high load carrying capacity and safety performance;

  Because the double-row tapered roller bearing has a better sealing structure, the clearance has been adjusted before installation, so this type of bearing is mainly used in high-speed rail bearings.

Locomotive Bearing

  Railway locomotive bearing vehicle wheel axle system adopts different structures due to other application conditions. The locomotive and passenger car has an axle box, and the bearing is connected to the bogie through the axle box. Cylindrical roller bearings are generally used.

Freight Car Bearings

  Wheelset bearings generally use cylindrical roller bearings.

Subway Bearing

  Generally, it is a double-row cylindrical bearing with sealing devices on both sides or two paired single-row cylindrical roller bearings with a sealing device on one side. The directions are pre-installed with grease.

All operators and manufacturers of rail vehicles, like passengers, want any A rail vehicle (from trams to high-speed trains) that has exceptionally high reliability And operational safety. Take the light rail vehicle as an example, the low floor is more concerned, And multi-group design, their running gears, bogies, and other components must be designed to be very compact.
