Stoffel Polygon Systems, Inc.

When splines or keys fail prematurely, Polygons are your Solution!

  • icon

    Polygons transmit nearly twice the torque of involute splines in the same shaft diameter.

  • icon

    Increase connection life on violent torque reversals.

  • icon

    Excellent concentricity, provide balance at high speeds.

  • icon

    Polygons are self-centering even on loose connections.

  • icon

    Easy to assemble, easy to clean.

  • icon

    Polygons high strength makes it possible to reduce connection size when space limitation is required.

  • icon

    Can be ground after hardening, avoiding heat treatment distortion.

  • icon

    Minimum backlash, even Zero Backlash with taper polygons, or press fit connections.

  • icon

    Peak Stress, half as high as in a spline, thus fatigue life is 10x greater.
