Maintenance-free bearings in transitions and rotating joints

Profile

• What was required? plain bearings and slewing ring bearings, energy supply for transitions and rotating joints between wagons
• Manufacturing process: injection moulding 
• Requirements: use under the influence of forces, shocks, vibrations  
• Material: iglidur G, iglidur Z
• Industry: railway technology - wagon construction
• Success for the customer: particularly durable and robust bearings and cables

Many different forces act in all directions on the transitions and rotating joints between individual carriages. These include push and pull forces, impacts and continuous vibrations. For such applications, robust and reliable bearings are especially important. iglidur plain bearings are a preferred choice for such use because of their high surface pressure, which can be up to 150MPa. The robust iglidur materials withstand even high edge loads without breaking. The wide variety of iglidur materials makes is possible to find exactly the right plain bearing for every possible application. These include for example materials for the use in particularly high or low temperatures, for constant movements or with high media resistance. Furthermore, PRT slewing rings are used in light-rail vehicles in the rotating joint on the floor.  The service life can be calculated online for all products. To guide cables safely between two wagons, e-chains by igus are used. These guide cables securely, not only within the train but also on the outside, despite torsion, movement and weather.
