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
  • RSB (Rough Stock Bore) hub has No Keyway or set screw hole, it is not useable as shown and must be machined to proper bore tolerances Hub includes inside sleeve and is drilled and tapped for collar bolts. Non-standard bores available – consult Lovejoy Engineering.
  • Jaw coupling hubs are standard with one set screw, for two set screws see RRS & RRC sections.
