Leather seals and bellows
for the railway sector

In the railway sector, equipment works under constraints that few other sectors experience. Constant vibrations, humidity, temperature variations between interior and exterior and very long usage cycles wear components faster than elsewhere. The seals, bellows and sleeves that equip your equipment must last over time without frequent replacement. We have been manufacturing leather components for the railway sector for more than 130 years. Clients such as SNCF, Bombardier and Alstom trust us on their equipment.

Everything is manufactured in our workshop in ISO 9001 certification. Replacement part for equipment in service or small series for a new line, we respond to both.

Emile Janique products
used in the railway sector

Here is how our products intervene
concretely on your railway equipment.

Dynamic leather seals

For your door cylinders, suspension systems and displacement shafts on rolling stock and maintenance equipment. Leather withstands constant vibrations and dimensional variations without losing its sealing properties.

Cut seals

For the static sealing of your flanges, housings and connections on railway equipment. Available in leather, cork, NBR, EPDM, FKM or PTFE elastomers according to your constraints.

Moulded protective bellows

For your cylinder rods, shafts and articulations on suspension systems and onboard equipment. Manufactured in leather, PVC or silicone-coated Kevlar according to your environmental and temperature constraints.

Leather and silicone sleeves

For your onboard ventilation and air conditioning systems. Leather and silicone absorb vibrations transmitted by equipment in operation and ensure the long-term sealing of connections.

Leather belts and straps

For your transmissions and maintenance equipment for railway rolling stock. Leather is particularly suited to reciprocating motion applications and transmissions where synthetic belts are not appropriate.

Parts that last over time on your railway equipment

Dans le ferroviaire, les interventions de maintenance sont planifiées longtemps à l’avance. Un composant qui s’use trop vite force une intervention non planifiée sur un équipement en service. Nous fabriquons nos pièces pour durer dans vos conditions réelles de travail. Vous nous décrivez votre environnement, les vibrations, l’humidité, les températures. Nous choisissons le matériau et les dimensions adaptés pour que votre pièce tienne le plus longtemps possible entre deux interventions.

    FAQ: leather seals and bellows
    for the railway sector

    Do your parts withstand the constant vibrations of rolling stock?

    Yes. Leather is naturally flexible and absorbs vibrations without cracking or losing its sealing properties. That is one of the reasons we have been working on railway equipment for more than 130 years.

    Yes. Send us your worn part or a dimensioned sketch. We take the dimensions and manufacture the replacement, even if the original part is no longer available in the manufacturer's catalogue.

    Our parts are manufactured in accordance with our ISO 9001 certification and are documented and traceable. For specific regulatory requirements of your application, contact us directly with your technical specifications.
