The GMT Group is a leading worldwide specialist in the field of anti-vibration technology. For 50 years we have been manufacturing components and systems to reduce noise, shock and vibration. We provide solutions for all industry sectors such as general engine and machine builders, railway vehicle industry and aircraft industry.

GMT provide solutions to satisfy the requirements of complex anti-vibration systems in railway vehicles which are subject to various simultaneous forces.

We provide our customers high quality products which compensate for the diverse loads and stresses experienced by railways vehicles. Our economically conscious solutions are guided by the principals of efficient transmission of power, derailment safety as well as ease of maintenance.

Our extensive application experience and industry specific knowledge allow us to develop and manufacture high-performance products for primary suspensions in bogies as well as for secondary suspensions such as air spring systems. Modern FEA calculation programs are used to determine and indeed optimise the geometry and profiles of components to ensure fatigue life whilst minimising cost and weight.

Special calculation modules and methods confirm the suitability of our products; service life analyses and multi-axial dynamic tests verify their reliability. RAMS/LCC objectives are embedded in our development process.

Complex customer needs demand an intelligent approach when selecting and designing our components. Once installed, continued technical support is offered for the life of our products in order to guarantee optimal performance in the application.

However, we do not only consider ourselves as a supplier of a wide range of technical products and services. We are continuously collaborating with our partners to develop new and innovative technology to continuously extend our range of capability and to incorporate these into our products.

Our railway product range includes:

air spring systems, conical springs, chevron springs, layer springs, bushings, spherical bearings, deflection rods and torque multipliers. Recent new innovations include the upgraded hydraulic axle bearing, HYDRALL®, and our mountable elastomer wheelset axle protector, MERP which is used to prevent mechanical and material damage resulting from ice build up and impacts with track debris and foreign objects.
