Elastic Elements for Resilient Wheels
Resilient wheels incorporate an elastomer layer between the wheel centre and the outer metal section.
Pre-compressed rubber rings are installed within the wheel assembly so that operational forces are transferred through controlled elastomer deformation. This elastic separation reduces the rigid transmission of vibration and shock through the wheel structure.
Elastic Elements for Resilient Wheels

Pre-compressed rubber rings are installed within the wheel assembly so that operational forces are transferred through controlled elastomer deformation. This elastic separation reduces the rigid transmission of vibration and shock through the wheel structure.
Noise and Vibration Reduction
Wheel–rail interaction generates vibration and impact forces that can be transmitted through the wheel into the running gear and vehicle structure.
The rubber rings provide an elastic interruption within this transmission path. This helps reduce wheel-related vibration and noise and supports quieter, smoother vehicle operation.
These characteristics make resilient wheels particularly suitable for trams, light rail vehicles, metro vehicles and other urban rail applications.
Key Technical Benefits
- reduction of vibration generated by wheel–rail interaction;
- reduction of wheel-related noise;
- absorption of shock and impact loads;
- elastic separation of the inner and outer wheel parts;
- improved ride comfort;
- compact integration into the wheel assembly;
- application-specific geometry and elastomer characteristics;
- suitability for wheel refurbishment and replacement projects.
Applications in Resilient Wheel Systems
Pre-compressed rubber rings are used as elastic elements in resilient railway wheels where noise, vibration and impact transmission must be reduced.
They can be supplied for wheel overhaul, replacement of existing elastomer elements, fleet refurbishment, vehicle modernisation and new-production projects.
Each component must be matched to the construction and functional requirements of the respective wheel assembly.
Project-Specific Manufacturing
The geometry, elastomer compound and elastic characteristics of the rubber rings are developed according to the intended wheel design and operating requirements.
Project-specific components can be produced according to an existing technical drawing, original part, physical sample or defined customer specification.
Each application is technically reviewed individually before production.
German Production and Quality Control
Rubber rings for wheels are produced under certified quality management and controlled manufacturing processes.
Product-specific verification focuses on dimensional conformity, elastomer quality and the agreed compression and elastic characteristics. Additional validation is performed according to the technical requirements of the individual wheel project.
The finished products are supplied with an EN 10204 3.1 inspection certificate.
