- 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 specific Martin flange types (J type flanges in the case of JEM and JEMS type sleeves, and all flange types in the case of EM type sleeves) in the Quadra-Flex series flexible coupling assemblies (sold separately)
- Thermoplastic rubber for resistance to oil and higher temperatures
- Three types: one-piece solid (Type JEM), one-piece split (Type JEMS), and two-piece split with a metal retaining ring (Type EM) for applications where the coupled shafts are difficult to separate
- Operating temperatures range from -50 to 275 degrees F (-46 to 135 degrees C)
- For use with some flexible coupling assemblies (sold separately) in the Martin Quadra-Flex series
- Steel sintered with powdered metals for strength, durability, and corrosion resistance
- 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
