  • Standard L Type coupling hub materials are either sintered iron (L035-L190) or cast iron (L225-L276).
  • The L Type coupling consists of two standard L Type hubs and one spider.
  • Unless stated otherwise, hub torque and horsepower ratings assume a SOX(NBR) rubber spider is being used.

Spider Performance

 N/A
  • 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.)
