Request Information

The patented Deltaflex series of couplings offer maximum misalignment capabilities with negligible reactionary load, for longer equipment life. This all-metal flex-link coupling requires no lubrication or other maintenance.

A standard (Type 1, 2, or 2A) Deltaflex coupling is comprised of two hubs, an inner flange (which comes with hardware), and an outer flange.

*Note: As the inner flange comes with hardware, ordering hardware separately is generally not required.

Coupling Design

Coupling Design

 N/A
    The Deltaflex coupling is the real solution to installation, misalignment, and performance problems. Conventional couplings – even when carefully aligned to the manufacturer’s specifications – cannot match the low level of vibration, moment of inertia, and additional cushion for future misalignment of a visually aligned Deltaflex coupling.
    In addition, the Deltaflex coupling gives longer life to equipment shaft bearings. That means longer operating time and reduced maintenance cost. The Deltaflex can handle greater shaft misalignment without generating heavy reaction loads on the equipment shaft bearings.
    A properly applied and installed Deltaflex coupling offers more equipment protection compared to conventional couplings.

Features

Features 

 N/A
  • Maximum misalignment capabilities, with negligible reactionary load, for longer equipment bearing life
  • Operates as smoothly when misaligned as when perfectly aligned
  • No lubrication and no maintenance required
  • Equipment can be visually aligned. No special tools are required, which saves on installation time and cost
  • Eliminates premature equipment bearing and seal failure resulting from misalignment forces. This means greater equipment productivity
  • Torsionally stiff coupling with no backlash means it is capable of high speed applications, within catalog ratings
  • Provides long-term performance and economy
  • Available in 5 basic sizes, from 10HP to 900HP
  • Standard all-metal and stainless steel versions are both available from stock
  • Many configurations are available, including shaft-to-shaft, spacer, floating shaft, and special assemblies

Notes

Notes 

 N/A
  • Size 50: In some bore sizes the tap is 5/8-18.
  • Maximum bores are provided with standard keyway.
  • RSB hubs do not have a keyway.
  • Both Delta hubs and Round hubs are provided with two set screws at 120°.
