SK-1947-29 in Dynaflex® Shear Type Couplings Print Page Download PDF

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 Misallgnments-1/32 in. parallel, 2° angular.

    Shear-type Dynaflex couplings reduce the adverse effects of transient shock torques, torsional vibration, noise and misalignment associated with small equipment drivelines. This results in longer service life, smoother, quieter operation, less maintenance, and lower cost for your end product.

  • 1/50 to 1 hp at 1750 rpm.
  • High torsional deflection.
  • Versatile application potential.
  • Multi-directional misalignment accommodation.
  • Easy installation.
  • One-piece construction.
  • No lubrication or maintenance required.
  • Misalignment Accommodation : elastomeric flexibility accommodates misalignments up to 1/32 inch parallel, 2° angular.
  • Vibration Isolation : low torsional stiffness is achieved with the shear-type flexible coupling because the rubber is loaded in shear. This allows for low system natural frequencies and excellent driveline disturbances.
  • Shock Protection : torsional shock loads are attenuated by torsional deflection of the elastomer. Torsional flexibility smoothes out rotational disturbances and protects system components from early fatigue failure.
  • Noise Reduction : no metal-to-metal contact; elastomeric barrier reduces gear noise, transmission and motor hum between shifts.
  • Maintenance-Free : elastomer flexibility accommodates all motion without metal-to-metal wear, eliminates the need for lubrication.
  • Long Service Life : shear-type flexible couplings have proven themselves under demanding service conditions. Elastomers resist effects of abrasive materials, oil and grease.
  • Attachment : shear-type flexible couplings are available in an assortment of bore sizes.
  • Constant Velocity : inherent design properties produce a rotational constant velocity.
