  • Torque limited only by clamping force between coupling and shaft
  • Simple, economical
  • Low moment of inertia
  • Driving and driven shafts maintain relative angular position
  • Metallic versions can accommodate virtually no shaft misalignment, and nonmetallic versions only trivial amounts of misalignment - and some shaft misalignment is always present between any two shafts. Even after precision alignment, thermal expansion during operation will lead to some radial misalignment if both shafts are fully radially constrained.
Typical Applications:
Devices with enough internal clearances or flexible members (flexible shafts, spring washers, and so on) to accommodate any incidental shaft misalignment without a flexible coupling; consumer products, material handling equipment

  • Materials: Nickel-plated 1018 steel, alloy 7075 aluminum, alloy 303 stainless steel, Ultem (offering electrical insulation)
  • Shaft attachment options: Set screw without keyway, set screw with keyway, clamping without keyway, clamping with keyway
Advantages of OEP's Rigid Couplings over those of other manufacturers:
  • All rigid couplings are precision-machined from bar, offering better strength, fit, and overall quality than cast or powdered metal couplings.
  • Machined to tighter tolerances than those of other manufacturers, improving fit between shaft and bore, dynamic balance, and so on.
  • Full range of sizes, materials, and shaft attachment options available
