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.)



  • Radially removable insert
  • Collar allows for maximum speed of 3,600 RPM
  • Collar manufactured from 1018 Steel



  • These “LC” hubs are drilled and tapped to accept collar mounting screws but the collar and hardware are not included.
  • All hubs are supplied standard with one set screw.
