  About Us       

These 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.

Shear-Type flexible couplings are useful in many small equipment driveline applications. Multi-directional misalignment capabilities make them ideally suited for fractional horsepower drivelines demanding noise reduction, vibration isolation and maintenance-free operation.

Features & Benefits

  • Easy installation
  • Versatile application potential - fractional horsepower couplings are available in a range of sizes to permit matching a specific coupling to your application.
  • One-piece construction – convenient for small equipment with fractional horsepower requirements. Specifi ed torque rating allows 15° angular defl ection for excellent vibration isolation.
  • Multi-directional misalignment accommodation – elastomeric flexibility accommodates misalignments up to 1/32 inch parallel, 2° angular.
  • High torsional deflection
  • 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 smooths 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 – Dynaflex Shear-Type 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. Refer to Table 1.
  • Constant velocity – inherent design properties produce a rotational constant velocity.
