The automotive, rail, and heavy-duty equipment sectors operate in some of the harshest mechanical environments. Components must perform reliably under constant vibration, exposure to oils and fuels, temperature fluctuations, and high dynamic loads. Every seal, bushing, guide ring, or sliding element must resist deformation and wear, even in long-term, heavy-duty conditions.
Passenger and commercial vehicle manufacturing
Construction, agricultural, and municipal machinery
Rail transport — from locomotives to rolling stock systems
Power units, hydraulic systems, and large mechanical assemblies
In transportation technology, polymer-based components play a critical role in maintaining performance and safety:
Seals in hydraulic and braking systems
Shaft seals, O-rings, wipers, and guide rings
Bushings and support sleeves in suspensions and axles
Heat- and chemical-resistant gaskets in engines and gearboxes
Protective and sealing elements for cable passages and housings
Constant mechanical stress and vibration
Temperatures up to +200 °C
Contact with oils, fuels, coolants, moisture, and dust
Seasonal freezing/thawing cycles
Sudden changes in pressure and load
