Special designs

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.

Our polymer springs are used in a wide range of application (railway industry, heavy engineering, automotive industry, oil-producing industry, shipbuilding, mining industry, machinery and etc.) worldwide. At the list below, you can find turn-key solutions according to your requirements, with detailed descriptions of parameters and technical characteristics of each spring. In the event that you can’t find the suitable polymer spring, use the PACKAGE SELECTION service or CONTACT US .
