Polyurethane dampers are essential components used across various industries to absorb vibrations, reduce noise, and extend the lifespan of mechanical systems. With increasing demand in the automotive, rail, construction, and heavy machinery sectors, polyurethane (PU) has become a preferred material due to its superior durability and resistance to wear.
Why Choose Polyurethane Dampers?
Compared to traditional rubber dampers, polyurethane vibration dampers offer greater tensile strength, resistance to oils and chemicals, and longer service life. Their high load-bearing capacity and excellent flexibility make them suitable for applications with dynamic forces or repeated impact.
- Superior resistance to abrasion and fatigue
- Excellent performance under high loads
- Long-term stability in harsh environments
- Lightweight and easy to install
Typical Applications
Polyurethane dampers are widely used in:
- Railway primary and secondary suspension systems
- Excavators, bulldozers, and mining equipment
- Automotive suspension and chassis systems
- Industrial compressors and machinery mounts
