- For use with Martin Spacer Coupling (SC) type Quadra-Flex series flexible coupling assemblies (sold separately)
- High carbon steel for better wear and longer life over hubs made from steel alloys with less or no carbon, or non-steel alloys
- Available in regular (H type) or short (HS type) lengths to accommodate the spacing requirements of the application
- Attaches to SC type spacer flanges with four bolts
- For use with Martin Super (MS) series jaw style flexible coupling assemblies (sold separately)
- Steel sintered with powdered metals for strength, durability, and corrosion resistance
- For use in applications involving high horsepower
- Flexes up to 1 degree to compensate for angular misalignment of coupled shafts
- Operating temperatures range from -45 to 210 degrees F (-42 to 99 degrees C)
- For use with Martin Quadra-Flex series flexible couplings (sold separately)
- Cast iron for non-corrosive applications where strength and heat dissipation are factors and weight is not
- For use with Martin Quick Disconnect (QD) bushings to facilitate the swapping out of portions of the coupling assembly to accommodate changes in the demands of the application
- Transfers shock and misalignment to the center element of the coupling assembly for reduced wear on the shaft assembly
- Teeth help to distribute torsional load across the flange and sleeve, reducing wear and extending service life
