Application areas for our components in railway technology

High-performance polymers and cables - motion plastics® - help to reduce weight by replacing heavy metal components with lightweight and durable polymer components. Their special material properties make them resistant. They are unaffected by dirt, heat, cold, moisture and road salt. That's why they are used inside and outside in rail-bound traffic and transport.

What application areas can you find on this page?

Interior

Railway technology Controllers and switches Lever Bearing point

Wear-resistant controls in the driver's cab

The properties of motion plastics are also advantageous in the controls used to operate trains and trams. Bearing points in control panels, for example, are fitted out with iglidur G plain bearings for a high level of wear resistance. Adjustable floor pedestals have been fitted with dryspin lead screws and enable easy adjustment.
Seat with iglidur plain bearings, drylin linear guides and a PRT slewing ring bearing

Maintenance-free and clean in the passenger area

iglidur plain bearings and drylin linear technology ensure clean adjustment, low coefficient of friction and low-noise movements without the need for any additional lubrication. This is due to the incorporated dry lubricants, which are within the igus materials. If the components have to be in line with DIN 45545, iglidur RW370 can be used. 

Exterior

Railway technology pantograph

Insulating high-performance polymers in pantographs

As iglidur plain bearings are made of non-conductive high-performance polymers, they can be used as insulating components in bearings on collectors. Due to their incorporated solid lubrication, the plain bearings do not require additional lubrication and are therefore maintenance-free. In pantographs, the iglidur materials G, H370, J, W300, X and Z are installed. Each of these materials has certain advantages, e.g. low moisture absorption or resistance at particularly low or high temperatures. 
Coupling with iglidur plain bearings

Reliable and lubrication-free coupling

Railway couplers profit from the high reliability of iglidur® plain bearings and thrust washers. In Scharfenberg couplings, e.g. they are used in the main pin so that the hooked plate can turn during coupling. The plain bearings do not require any additional lubricants and are therefore maintenance-free.
Train brake with iglidur plain bearings

Heat-resistant, corrosion-free plain bearings for brakes

iglidur® plain bearings are built into train and tram brakes as they enable trouble-free operation where impacts and dirt occur and do not corrode. Use within wide temperature ranges between -100°C and 250°C are made possible by special materials that have been developed for extreme temperatures.

Infrastructure

Switch roller in turnout with iglidur plain bearings

Switch roller in turnouts

A constant functionality of the switch device must be guaranteed despite weather and vibrations. igus plain bearings are perfectly suited for this use. All iglidur materials contain incorporated solid lubricants, which make additional lubrication and maintenance redundant.
Circuit breakers and earthing switches with plain bearings

Circuit breakers and earthing switches

Along the railway line and in the train itself there are circuit breakers and earthing switches. Whether with medium or high voltage - a safe mechanical separation and connection must be guaranteed in the switches at all times. To make this possible even under demanding weather conditions, drylin drive systems and lead screw are used. 
Gears in track switching

Gears in track switching

To reduce interruptions of rail journeys, track switches are used. They ensure the seamless transition of the rail vehicles from one track to another. 
The use of our wear-resistant iglidur® i3 gears contributes to a long service life of the application.

Wagons and railcars

Ventilation and pressure protection flaps for trains with igus components

Ventilation and pressure protection flaps

Both fresh air from the air conditioning and cooling of important electronics - in express trains and trams, constant air supply must be guaranteed and regulated. Pressure protection systems and ventilation flaps can be easily moved by means of different igus products.
Battery and control cabinet extensions with igus energy supply

Battery and control cabinet extensions

Under the carriage body a strong protection from falling rocks is necessary. In addition, the cables have to be guided safely so that the batteries can be pulled out without problems for maintenance. Therefore, robust energy chains and cables are often used for train battery boxes. Both components are also available as so-called readychain. 
Train door with different igus components

Fail-safe entry systems with a long service life

chainflex cables,dryspin lead screw technology and energy supply systems are used to make entry systems maintenance-free and, above all, durable. Defective doors can constitute a hazard to passengers in emergency situations and, in everyday life, are hindrance to speedy passenger boarding and alighting.

Maintenance

Lifting platform for trains with e-chains and chainflex cables

Lifting platform

The vehicle fleet requires regular maintenance. The lifting platforms and the cables and energy supply systems connected to them are therefore subjected to continuous stress. If the cables are not guided securely, wear is accelerated and failures can occur. 
Train on traverser

Traversers with readymade energy supply

Traversers connect tracks in workshops and in the open with each other to move wagons and control carriages and locomotives. While the transverser is in motion, a safe power supply must be available at all times, e.g. with signal lamps or a control panel. To guarantee the permanent functionality of the transverser despite frequent use, chainflex cables are used. 
Train in washing system

Corrosion-free bearings and energy supply systems for washing systems

At washing systems for regional and express trains, igus components must show what they are capable of. Permanent use is combined with contact with water and cleaning agents. No problem for the igus components. iglidur plain bearings are available in 50 different high-performance polymers.

Special rail vehicles

Shunting locomotive with igus components

Shunting vehicles

igus offers a variety of solutions for shunting locomotives. From the drylin drive technology and PRT slewing ring bearings to bar stock plates and tribotape. All these components contain high-performance polymers and are optimised for low wear and friction to guarantee a long service life.
Railway construction machines with igus components

Durable polymer solutions for track-laying machines

In order to build new tracks for trains or trams, complex machinery is needed. Bearing points in track construction machines are exposed to considerable mechanical forces, vibrations, dust and weather influences. All these factors are no longer a problem if iglidur plain bearings are used. For high mechanical forces, e.g. edge loads or impacts, there are specially developed iglidur materials that can withstand static loads up to 200MPa and dynamic loads up to 140MPa. 
Road-rail vehicle

Calculate service life of e-chains and cables for road-rail vehicles

igus components are not just used in trains and trams. They can also be found in road-rail vehicles, such as snowploughs and maintenance vehicles. By means of hydraulic cylinders, the bogie of these vehicles can be lowered. In the cylinders, materials and piston rings made of iglidur materials are used. They are characterised by their extremely long service life and are also maintenance-free. 

Tools

Track distance measuring device with drylin component

Distance meter for rails

drylin linear guides are used in distance meters for rising height and gauge measurements. The preferred tool is the smallest series 4 drylin N and drylin T linear guide These are particularly space-saving and weight-saving. drylin linear guides withstand dirt and rain, as they do not require additional lubrication. Therefore, they are perfect for outdoor use.

Measuring machine for rail profiles

Measuring machine for rail profiles

In measuring machines for rail profiles, self-adjusting igubal bearings are used. Due to their angular compensation, they are ideal for manual adjustments. Furthermore, drylin SLW linear guides are installed for the adjustment of width and height, as they are cost-effective and weight-saving. drylin R carbon fibre shafts with drylin R polymer housing bearings are applied in machines to save weight.
Grinding machine for rails

Grinding machine

To adjust the height of a grinding machine, dryspin lead screws are used. The lead screw nut consists of proven iglidur materials, which contain dry lubricants. Therefore, they require no additional lubrication and are also maintenance-free. As the lead screws are made of stainless steel, dryspin lead screws do not rust. To save a particularly high amount of weight, anodised aluminium lead screws can be used.
