Product catalog summary
Overview: The D-Flex Elastomeric Sleeve Couplings are designed for flexibility and versatility, accommodating shock-load, vibration, and misalignment. They are an economical solution for various coupling applications, featuring molded, non-lubricated, interchangeable elastomeric sleeves made from EPDM, Neoprene, or Hytrel.
Specifications:
  • Sizes range from 3 to 16.
  • Bore range: 0.375” to 6”.
  • Outer diameter range: 2.06” to 18.88”.
  • Misalignment capability varies by size and design, with angular misalignment from 0.125° to 1°, parallel misalignment from 0.01” to 0.062”, and axial misalignment from 0.03” to 0.125”.
Performance: The couplings have a torque capacity up to 72,480 in-lbs and a horsepower range up to 2,000 HP at 1800 RPM. They are torsionally flexible to accommodate shock, wind-up, and vibration, absorb angular misalignment, minimize radial bearing loads, and allow for shaft end-float.
Types of Couplings:
  • Type J-Flanges: Economical, available in four sizes, suitable for applications up to 10 HP at 1750 RPM, with EPDM or Neoprene sleeves.
  • Type S Couplings: Feature AGMA 9 balanced flanges, available with EPDM, Neoprene, or Hytrel sleeves, and offer a reborable option.
  • Type B Couplings: Use standard QD bushings, constructed from high-strength cast iron, available with EPDM or Neoprene sleeves.
  • Type SC Spacer Couplings: Designed for pump applications, accommodate a wide range of shaft spacing, and feature dynamically balanced flanges to AGMA Class 9 Standards.
Sleeve Options:
  • EPDM: Temperature range -30°F to +275°F, max angular misalignment 1°.
  • Neoprene: Temperature range 0°F to +200°F, max angular misalignment 1°.
  • Hytrel: Temperature range -65°F to +250°F, max angular misalignment 1/4°.
Compatibility: The document provides a detailed compatibility chart for flange styles with different sleeve materials, indicating which combinations are suitable for various applications.
