Polymer Springs
Polymer Springs
Kraftler specializes in designing, engineering, and manufacturing components for industries requiring high energy absorption, such as railway, automotive, and heavy engineering. The company is known for its expertise in damping systems and energy absorption.
Product Specifications
Kraftler's polymer springs are designed to withstand extreme loads and physical damage. They are manufactured using a unique patented technology, offering superior performance in temperatures ranging from -60°C to +60°C. These products are resistant to chemicals, grease, oils, solvents, and abrasive environments.
Performance Metrics
- Energy absorption: Ranges from >3 kJ to >35 kJ depending on the model.
- Damping: Typically >30%, with some models achieving >60%.
- Pre-tension force: Varies from ≥3.6 kN to ≥150 kN.
- Max. End force: Ranges from ≤320 kN to ≤1350 kN.
- Stroke: Varies from ≤1.5 mm to ≤223 mm.
- Pad Diameter at full stroke: Ranges from 160 mm to 280 mm.
Material and Technology
The polymer pads are made from high-performance TPE elastomer, which surpasses metal, rubber, urethane, and hydraulic-based springs in terms of life cycle, reliability, and fatigue resistance.
