For railway vehicles
Kraftler polymer springs have high energy absorption that don’t require any maintenance for an extended life of your equipment. Superior performance in temperatures range from -60°C to +60°C. All products have an excellent resistance to chemicals, grease, oils, solvents, and abrasive environments.
The polymer springs, shown at the table below, are used in buffers, draw-gears, and in others railway devices.
