HeaderMilitary and Aerospace Spline Couplings Machined from DuPont™ Vespel® Parts & Shapes

A proven technology for reducing spline wear and increasing service life.

NEW White Paper highlights the benefits of specifying spline couplings made from DuPont™ Vespel® for use in critical-service military and aerospace spline connections.

  • Reduced wear on metal splines
  • Extended service life for spline connections
  • Ductile behavior of spline couplings allows for some degree of shaft misalignment
  • Couplings reduce the stresses on bearings when shafts are misaligned
  • Spline couplings can eliminate the need for external lubrication in certain applications
