TB Wood’s Dura-Flex couplings “split-in-half” elementdesign allows for easy element installation/replacementwithout moving connected equipment or disturbing theshaft connection.Spacer design can accommodate a large range of shaftspacing with few parts. Patented design of the urethanebond to the leading edge of the steel shoe bolted to thehub, minimizes bond stress for long coupling life.These couplings are highly flexible and able toaccommodate shaft misalignments (1/16” parallelmisalignment and 4? angular misalignment) whileminimizing torsional vibration and preventing damageto connected equipment.Specially formulated polyurethane material providessuperior weathering, chemical resistance, and dynamicproperties.

Sure-Flex®Elastomeric Couplings:Sure-Flex is a TB Wood’s original! Sure-Flex Couplings utilize a rubber(EPDM or Neoprene) or Hytrel™ thermoplastic flex element (sleeve)to transmit torque and accommodate shaft misalignments. Sure-Flexcouplings have exceptional torsional flexibility, and the 4-way flexingaction absorbs virtually all types of shock, vibration, misalignment, and

end float. These couplings are an excellent choice when low cost, highflexibility, vibration damping, and easy installation are primary concerns.Models available with torque capacitiesup to 8.20 kNm; 72,480 in.lbs.

L-JawElastomeric Couplings:Jaw-type elastomeric couplings are an economical, proven solution

for general purpose applications. Jaw couplings are easy to installand require no lubrication or maintenance. Four different flexibleinsert types are available: Buna-N rubber, Urethane, Hytrel™ and

Bronze. Jaw couplings are an excellent choice for all light andmedium duty general purpose industrial applications. Modelsavailable with torque capacitiesup to 0.70 kNm; 6,228 in.lbs.

G-FlexGrid Couplings:State-of-the-art design from Bibby Transmissions, the original gridcoupling manufacturer. G-Flex is an all-metal coupling that providespositive protection against the damaging effects of shock loadsand vibration. Aluminum horizontal cover (T10), and all-steel verticalcover (T20) designs are available. G-Flex tapered grid couplings arean excellent choice where torsional flexibility/vibration damping areprimary concerns. Models available with torque capacitiesup to

169 kNm; 1,500,000 in.lbs.
