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.

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 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 shaft double row tapered roller bearings have the following characteristics:High load bearing capacity: Double row tapered roller bearings are designed with two rows of rollers, so they can withstand large radial and axial loads.High temperature resistance: suitable for high-speed operation and high temperature environment, with good heat resistance.Strong aligning ability: can maintain good working performance when bearing installation is not accurate or axial displacement.Easy assembly and disassembly: double row tapered roller bearing structure is relatively simple, easy disassembly

Structure: Railway bearings are generally composed of inner ring, outer ring, rolling body and cage and other components. The inner ring is directly connected to the shaft, the outer ring is installed on the wheel, and the rolling body is located between the inner and outer rings, which reduces friction through rolling and maintains the normal operation of the bearing.

Tapered curler bearing refers to the radial thrust kind rolling bearing whose rolling physique is a tapered roller. There are small cone angles and giant cone angles. The small cone Angle usually bears the radial and axial mixed hundreds ordinarily primarily based on radial loads, regularly used in double, reverse installation, the internal and outer seat rings can be established respectively, and the radial and axial clearance can be adjusted throughout set up and use.

The structure of Koyo tapered roller bearings mainly includes an outer ring, an inner ring, a rolling body (roller) and a cage. The rolling element is located between the inner ring and the outer ring and is kept in the specified axial position by the cage. The contact Angle between the inner ring and the outer ring is generally between 10° and 30°, and different contact angles will affect the bearing capacity and speed limit.

The working principle of Koyo tapered roller bearings is to use the rolling body to roll between the inner and outer rings, thereby reducing the contact area and reducing friction resistance. When the external radial or axial load is applied, the roller will bear the load between the inner and outer rings to achieve the function of supporting and transferring the load of the bearing. Rollers are designed so that they can equally share load when rotating, reduce local stress and extend service life.

In industrial manufacturing and various mechanical equipment, rolling bearings with seats are widely used in heavy machinery, automobiles, aerospace, railway traffic and other fields. For example, in the automotive industry, rolling bearings with seats are used in engines, transmissions, steering systems and other components to support and transmit rotating forces.

UBC tapered roller bearing is a kind of rolling bearing with tapered roller, the roller and raceway between the inner ring (cone hub) and the outer ring (cup) intersect at the cone half Angle on the outer surface of the cone, so that the bearing can bear a large load in the radial and axial direction. UBC tapered roller bearings usually include single row, double row and four row structures, which are widely used in automotive, mechanical equipment, aerospace and other fields.

In rolling bearings, the bearing ring is separated by a rolling unit (rolling element), and in slide guidance systems, the movable part slides on a static guide rail or shaft. Depending on the type of track system, the sliding layer is on movable or rigid components. The lubricating oil is embedded in the sliding layer to achieve lubrication. INA linear plain bearing is a linear positioning bearing with infinite stroke length.

Four row tapered roller bearings are mainly used for work rolls, support rolls, and billet breakers of various plate and strip rolling mills. The clearance of the bearing is changed by adjusting the thickness of the spacer to make it more suitable for the working condition.1. Strong bearing capacity: four row tapered roller bearings can withstand greater loads under the same size, because it is shared by multiple rollers, so it has higher carrying capacity and better distribution performance.2.

Because the rolling body in the thrust tapered roller bearing is a tapered roller, the rolling surface can form a pure rolling and the limit speed is higher than that of the thrust cylindrical roller bearing because the rolling bus and the raceway bus of the washer converge at a certain point on the axis line of the bearing.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)294169039416801705446813802000–5.9129412903941260130422938542700—2.61294139039413651404534410002500—3.342

A double-row tapered roller bearing is a common bearing type that consists of two tapered rollers mounted on an inner ring and an outer ring. It can withstand large radial and axial loads and is able to maintain high accuracy and stiffness while rotating at high speeds.Double row tapered roller bearings are designed so that the inner and outer rings can be adjusted separately to achieve axial and radial preloading.
