Steel Flex Couplings


Steel Flex Couplings

FLEXITECH originated the tapered grid design as well as shot peening to increase fatigue strength and torque ratings. Steelflex redefines total coupling value up to 7.5 million in-lb., 932 000 Nm torque. Steelflex offers simpler initial installation than gear couplings. The unique “replace in place” design eliminates the need to move hubs or re-align shafts, reducing element change-out time. When you look at the overall savings in initial costs, spare parts costs, and labor costs for
Installation, alignment and replacement - plus improved ratings and a 5 Year Heavy-Duty Warranty - it’s easy to see what Steelflex Grid Couplings have over the competition. No other coupling in the torque range can touch Steelflex for cost-effective performance and reliability.

GRID FLEX the lowest lifetime operating cost
Tapered grids, made of high strength alloy steel, are quenched and tempered to spring hardness. The Grid surface is then precision shot peened to compress the surface molecules. The effect is a dramatic increase in rating, providing reserve strength for longer life or allowing a smaller size coupling to be selected. This precision technology was originally used in the production of sophisticated aircraft components.

FEATURES:

  • All metal construction having no fast wearing out components.
  • Accurately machined. Dynamic balancing is normally not required.
  •  Torsion ally flexible. Progressive torsional flexibility (due to curved profile) provides protection against shock load, impact load and vibration.
  • Heat treated spring steel grid absorbs high impact shocks without loss of energy.
  •  Transmits full torque with dampened vibration and reduce peak loads.
  • When over load occurs; grid fails and prevents failure of the shaft or machinery part connected to the coupling.
  • When parallel misalignment is too severe; the related machine is protected by the virtue of shearing of Grid or Tooth.
  • Extended life of parts of machines (Mechanical seal and Bearing etc.)
  •  Easy to install.
