Spider Performance

Spider Performance

  • Nitrile Butadiene (Buna N) Rubber is a flexible elastomer material that is oil resistant, resembles natural rubber in resilience and elasticity and operates effectively in temperature range of -40° to 212° F (-40° to 100° C). Good resistance to oil. Standard elastomer. (Also applies to SXB Cushions.)



  • Greater torque and bore capacity than the L-Line series jaw coupling
  • Elastomeric cushions are radially removable
  • Cushions available in SXB rubber and Hytrel



  • Jaw coupling hubs are standard with one set screw, for two set screws see RRS & RRC sections.
