Custom Spline Shafts Manufacturing

Grob continues to be one of the finest spline shaft manufacturers in the industry. Capable of making spline shafts for a variety of high torque equipment, our specialty services help to produce an expansive range of both industry standard and custom.

At Grob, we understand that every application is different.  We manufacture our own tooling which gives us the flexibility required to produce spline shafts to our customers exact specifications.

Grob’s engineers collaborate closely with customers to ensure that our custom spline shafts meet even the most unusual and complex specifications within tight tolerances. To confirm operational compatibility, a sample of every custom shaft goes directly to the customer for testing prior to commencing production. Moreover, our honed cold rolling process can produce superior spline shafts in a variety of configurations, including:

  • Straight-sided spline shafts
  • Involute spline shafts
  • Metric spline shafts
  • Custom spline shafts

Whatever your needs, Grob has the knowledge and equipment to design and manufacture top quality splines to suit nearly every application.

Advantages of Spline Shafts

Spline shafts are particularly useful for high torque applications because of the even distribution of the load across numerous teeth. This allows the spline shaft to transmit more power than traditional keyed shafts.  The tooth geometry on spline shafts also helps to maintain shaft alignment, preventing slip or backlash, that can reduce power output and damage equipment. Fortified by rearranging the grain structure of the material over the entire tooth profile, Grob’s innovative cold-rolling process gives spline shafts the greatest amount of strength near the bottom or the root area of the spline shaft, where it is most crucial.

Custom Profiles

In addition to custom spline shafts, Grob stays happily committed to cold rolling of custom profiles. We understand that every application demands different profiles, and sometimes standard profiles simply do not fit the task. As dedicated providers of precison and detailed custom profiles, Grob strives to fulfill every specification.

Our highly experienced engineers cooperate closely with our customers to design and manufacture the perfect custom profile for every application. To ensure the custom profile meets specifications, a sample will be sent to the customer for testing prior to the start of production. Whether you require assistance with a new proprietary component or a reverse-engineered replacement part, Grob has the knowledge and capability to meet your custom profile needs.

Custom Profile Applications

Grob is pleased to offer a variety of custom profiled parts, including:

  • Gerotor
  • Spline Shafts
  • Spur Gears
  • Timing Belt Pulleys

Quality Custom Splined Shafts and Profiles from Grob

Since 1951, Grob has been the leading provider of innovative cold rolling solutions for industries around the world. The “Grob Rolling” method revolutionized spur gear and spline manufacturing in the 1950s, and our dedication to superior manufacturing techniques continues today. Using cold roll forming to create bar stock, we take pride in producing less waste than traditional hobbing processes—all with the added benefit of increased product strength and durability. Only possible with the “Grob Rolling” process, a signature quality finish further reduces overall manufacturing costs.
