Product Description
High Strength Flexible Rubber Coupling PU Spider Coupling - Wear Resistant
Product Description

Rotex Spider, GR Spider, GS Spider, PU Spider, Polyurethane Spider

Our polyurethane elastomeric coupling spiders are manufactured using advanced polymer synthesis technology, combining the high strength of plastic with the elasticity of rubber. These components are designed for superior performance in demanding industrial applications.

Key Features
  • Exceptional hardness range (Shore A10-D80) with maintained elasticity
  • Superior tensile strength and load capacity compared to standard rubber
  • Outstanding wear resistance - 3-5 times more durable than conventional rubber
  • Excellent resistance to oils, fuels, and mechanical lubricants
  • High resistance to oxygen, ozone, and radiation exposure
  • Superior vibration absorption and damping characteristics
  • Reliable performance across wide temperature ranges
  • Precision machined for perfect fit with metal shaft couplings
