Railway Bearings play an important role in both passenger and goods transport.  They have to withstand heavy loads: they work at high speeds, under a great weight, are  Rolling bearings in railway gearboxes must withstand a wide variety of operating conditions and complex environmental influences. Not only are high static and, in particular, dynamic loads present in the form of vibrations and shocks, but the rolling bearings are also operated intermittently below the permissible minimum load.

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. They are able to accept loads of hundreds of tons on EMUs or locomotives and transfer them to the tracks, reducing wear on the tracks and other vehicles.2.

Railway Axle BearingsAxle bearings: tapered roller bearings, tapered roller bearing boxes, cylindrical roller bearings, spherical roller bearings. Railway axle bearings can be subjected to high shocks and loads. Mounting space is also limited, so in many cases compact, double-row bearings with high load ratings are used.Railway Axle Box BearingAxlebox bearings should have a large load carrying capacity, be able to resist shock vibration, and must have a high life expectancy, safety and reliability, smaller size and quality.

Railway bearing is a kind of application in railway bearing, wheel bearing railway locomotive vehicle shaft systems with different application conditions with different structural design, locomotives, passenger car axle box, bearing through the axle box connected to the bogie, railway wagon axle box, bearing with bogie side frame connected by load-bearing saddle bearing wheel and impact load between the bogie frame, and more Corners is under the axial load of wheel bearing structure contains a cylindrical roller bearing, cylindrical roller bearing unit, taper roller bearing, tapered roller bea

Railway bearing is an important component used to support and guide the rotation of railway vehicle axle, which bears the weight of the train and the force generated during operation, and can ensure the smooth operation of the train. Railway bearings play a vital role in railway transportation, and their quality and performance directly affect the safety and efficiency of trains. Railway bearing is an indispensable component in railway transportation, its structure is firm, reliable quality, wear-resistant and durable, to ensure the safety, stability and efficient operation of the train.

Inch taper/tapered roller bearings belong to separable bearing, as the outer ring, also called cup, is separable and easy for assembly.

Single row tapered roller bearing is a common rolling bearing, which is composed of an inner ring, an outer ring, a roller and a cage. Its structure is similar to a conical shape, which is why it gets its name.The contact points on the inner and outer rings are conical and suitable for bearing large loads in both radial and axial directions.

Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction.The type code of tapered roller bearings is 30,000, and tapered roller bearings are separable bearings.

Double-row tapered roller bearings have many advantages in structure and performance, so they are widely used in industrial production.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)302027202E15351114.913.412000160000.053302037203E17401220.821.89000120000.079302047204E20471428.230.58000100000.126302057205E25521532.237700090000.154302067206E306217.543.250.5600075000.231302077207E35721754.263.5530067000.331302087208E4080186374500063000.422302097209E45851967.883.5450056000.474
