Tenmat have been designing and manufacturing industry-leading products, which are now considered to be the industry standard, for over 100 years. Tenmat not only manufactures standard train bearings and wear parts, but also bespoke solutions to operate in specialised applications within the passenger, freight and locomotive industries.

Tenmat is the only company worldwide that can produce genuine RAILKO and FEROFORM materials which have the major advantage of Tenmat’s reinforced composites.

Why choose Tenmat?

RAILKO and FEROFORM are widely recognised as the industry standard for demanding applications within the railway industry and are the preferred choice for safety-critical wear parts on freight wagons. Tenmat have been leading the development of materials and products used for railway bearings and wear parts in the rail industry for over 100 years and all materials are approved by all major railway authorities and OEMS.

 High Corrosion and Temperature Resistance

Approved by all Major Rail OEMs and Authorities

High Dimensional Stability for Improved Efficiency

Fully Certified to EU Fire Safety Regulation EN 45545

Who we work with

We are approved, specified, and supplied to the large railway authorities, including Deutsche Bahn, SNCF, RENFE, British Rail and many others.

In 2006, TENMAT LTD purchased RAILKO LTD, which is now a wholly-owned subsidiary of TENMAT. Our impressive portfolio of previous projects includes flagship systems such as SNCF’s TGV trains, Deutsche Bahn ICE trains, and Alstom Pendolino trains.

Major rail systems benefit from our products, including Bombardier Aventra trains for UK Cross Rail, Bombardier AGC trains for SNCF, and Bombardier REGIO 2N double-decker trains used by SNCF.

Examples of our design expertise are seen on Kinkisharyo Light Rail in New Jersey, Bombardier Trams in Cologne, and the Alstom-built Paris Metro.



TENMAT’s RAILKO NF21 is the only material specified in all types of freight wagons including coal hopper wagons, oil tankers, salt/silt/aggregate wagons, heavy-duty wagons and dangerous chemical tankers.

RAILKO NF21 and NF22 grades have a resin-bonded composite structure with added friction modifiers to give controlled friction. This grade has been developed as a high performing wearing and bearing material, with uses in many industrial applications as it offers low wear and friction rates.

Leading European wagon owners specify Tenmat materials for safety-critical applications because FEROFORM and RAILKO materials are proven to significantly outlast elastomeric alternatives which ultimately means more time between repairs. By specifying RAILKO or FEROFORM wagon owners can be sure that repair yards are only installing the longest lasting and safest wear parts possible.

Passenger Rail

RAILKO and FEROFORM are considered to be the industry standard for railway bearings, wear parts and components worldwide and specified by all major passenger railway OEMs for use in high-speed trains, intercity commuter trains, metros, trams and light rail.

High speed rail

Tenmat is a key supplier of low noise, bespoke railway bearing components into many major high-speed rail projects across Europe. These high-performance and durable products allow the industry to continue to build its high levels of safety.

Typical applications for TENMAT components in high-speed trains include gangway tread plates, tilting system support plates, door opening system bushes, anti-roll bar bushes, tilting system support plates and current collector bushes.

Intercity commuter rail

By installing TENMAT train bearings and components, leading OEMs and rail operators are able to constantly increase the capacity of modern networks. These reliable products offer better protection to keep rolling stock operating at high levels.

Tenmat’s Feroform and Railko materials are used within the Scharfenberg coupler.


Light Rail

Tenmat high-performance train bearings are lightweight and widely used by all leading rail manufacturers in demanding applications such as suspension bushes, suspension washers, centre pivot plates, side sliding plates and engine coupling washers. RAILKO and FEROFORM railway bearings and materials excel in very difficult working environments, even in high salt and dust concentrations along coastal lines and in an arid desert.

Tenmat train bearings and components give full protection to vital parts in trains, helping to maintain high efficiency and performance levels across the lifetime of a train.

FEROFORM T814 is the leading solution for replacing metallic railway bearings with a lubricant-free and high-performance solution. FEROFORM T814 will not seize or pressure weld. Its dry running capability minimises maintenance requirements, as well as being lightweight for better fuel consumption.
