Dynaflex® Shear Type Couplings

For Low Frequency Vibration Isolation and Misalignment Accommodation

Compact, one-piece flexible couplings economically constructed to isolate low-frequency vibration and accommodate multi-directional misalignment.

Large Selection of Standard Sizes

Fractional horsepower couplings are available in a range of sizes to permit matching a specific coupling to your application.

Standard Construction:

  • Hubs – steel
  • Bores – as listed
  • Set Screws – one per hub furnished but not installed
  • Flexing Element – neoprene

Compact, one-piece coupling construction is convenient for small equipment with fractional horsepower requirements. Torsional deflection at rated torque assures excellent vibration isolation. Specified torque rating allows 15° angular deflection for excellent vibration isolation.

Max. recommended Misalignments: 1/32 in. parallel, 2° angular.
