Product Description
Polyurethane Spider Coupling
High Tensile Strength with Excellent Machining Performance
Available Types: Polyurethane Element Spider, PU Element Spider, GR Element Spider, GS Element Spider
Product Description
Polyurethane elastomer is a synthetic polymer material combining properties of rubber and plastic, offering exceptional performance characteristics:
  • Wide hardness range (Shore A10-D80) with excellent elasticity even at high hardness
  • Superior tensile strength, tear resistance, and load capacity compared to standard rubber
  • Outstanding wear resistance (3-5 times better than conventional rubber)
  • Excellent oil resistance with low affinity for non-polar mineral oils
  • Superior resistance to oxygen, ozone, and radiation
  • Exceptional vibration absorption and damping properties
  • Good low temperature performance and machining characteristics
Our couplings are precision-injected using high-quality TPU material or molded CSM/SBR, designed for various metal shaft coupling applications with superior performance in:
