description

  • Comprised of two hubs and a torque-transmitting polyurethane spider. The spider is press fit between the jaws, ensuring zero backlash operation while dampening shock to the connected components. The spiders are available in three durometers to meet various application needs. 98 Shore A spiders provide the greatest strength and torsional rigidity, 92 Shore A spiders are a balance between stiffness and compliance and 85 Shore A are highly compliant.
