Premium Power transmission couplings
Covers Fit Taper Bushed, QD and Stock, and Finished Bore Couplings.
Covers allow excellent lubrication, and their use is recommended to obtain maximum coupling life. Covers are of aluminum and are made in halves for easy installation.
Synthetic rubber oil seals, which contact the coupling hubs, retain the lubricant and prevent the entry of dirt.
Covers are fitted with gaskets between the halves.
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).
Material Rubber.
