For draft gears

Kraftler’s 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 that shown at the table below are used in the draft gears.
