Gear Cutting — Shaft Involute Splines and Straight Sided Splines
Splines cut directly onto a shaft, are one of the most reliable methods of transmitting torque between rotating components. Being able to get them right requires both the necessary equipment and an understanding of how splined connections behave under load.
Shaft Involute Splines and Straight Sided Splines Capacity
Milan's Machining cuts involute splines and straight sided splines on shafts up to 182 inches in length and 10 inches with a body diameter up to 18” OD, across a range of 3 Diametral Pitch to 32 Diametral Pitch (8 Module to 0.75 Module). What makes Milan’s unique is the length capacity. The long splined shafts can be a challenge in setup, support and maintaining consistency of the tooth form along the full length of the cut. That’s why Milan’s is here to help.

Shaft Involute Splines
Shaft involute splines follow the same curved tooth profile used in standard gear cutting. It gives them a self-centering quality when mated with a splined hub or bore. This makes it suited to applications where precise concentricity between the shaft and the component is important. In addition, their geometry distributes load evenly across multiple teeth rather than concentrating stress at any single point.
Straight Sided Splines
Straight sided splines use a simpler, flat-flanked tooth form that has proven itself as a reliable standard across heavy industrial and agricultural applications. Widely used in drive and power transmission, they also have the practical advantage of being straightforward to inspect during QA.
Both spline forms are cut to close tolerances. Whether you're replacing a worn shaft or supplying splined components into a new assembly, Milan's can help you achieve your goals.
