  • Small Eccentric Reaction Force
  • Allowable Misalignment
  • Vibration Absorption
  • Oldham type flexible coupling
  • Compact coupling with short overall length
  • Slippage between hubs and spacer allows high parallel and angular misalignments
  • Minimized load on shaft caused by misalignments.
  • Simple configuration enables ease of assembly
  • Protruded spacer design enables high allowable angular misalignment
  • Exhibits excellent electrical insulation
  • Operational Temperature: -20℃~80℃
  • Finished products featuring two different end bore diameters available in stock
  • Oldham coupling with no protrusions feature low allowable misalignment (1〜1.5°) due to interference between the spacer and hubs at the proximity of the outside diameter.
  • A bending moment is generated as well.
  • The MOS series features a high maximum angular misalignment (3°), enabled by the protrusions which act as points of support.
  • No bending moment is generated and the shaft load is minimized.
