  • 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
