shaft coupling

About Shaft CouplingsA shaft coupling is a mechanical part that connects the travel shaft and driven shaft of a motor, etc., so as to transmit ability. Shaft couplings present mechanical flexibility, rendering tolerance for shaft misalignment. Consequently, this...

High Performance Gear Couplings

Rigid Compression Couplings

  • For hard applications where strength and affordability are essential, the steel design of rigid compression couplings is suitable
    EP cast steel couplings are a great choice for joining two shafts of the same size
    This kind of coupling is also called a “rigid clamp style” coupling.

Motion Control Couplings

  • HP and RPM of the driver
    Shaft size of the driver and driven
    Application requirements
    Environmental conditions ( i. e. extreme heat, corrosive conditions, space limitations )
    Space Limitations ( i. e. maximum outside diameter and overall length for the coupling)
