Standard Spline Shafts

Grob Standard Spline Shafting has been designed to maximize torsional strength and contact area. Grob’s cold rolled spline shafts are made with an even number of teeth and are parallel over two or more teeth. When your project requires mating parts, look no further.

For your convenience we have off the shelf mating broached sleeves and flanged bushings to match our Grob Standard Spline shafts. We also offer custom broaching of your parts to match with our Grob Standard Splines.

  • Full Flank Fit
  • Large Contact Area
  • Equal size tooth to space ratio
  • The same pressure angle as parallel sided spline
  • 3 x’s the work surface of parallel sided spline
  • Mating sleeves or flanged bushings

Custom spline shafts & shapes are also available
