Step Shafts, Eccentric Shafts & Rotor-Shafts

Guaranteed Sound-Center Forged Shafts & Spindles

Scot Forge produces guaranteed sound-centered forged step shafts and rotor shafts from ferrous or non-ferrous materials with any combination of round, square, rectangle or polygonal dimensions, concentric or eccentric configurations and tapers or custom shapes. Parts with major diameters up to 65" or greater can be produced in weights up to 300,000 lbs.

Our skilled craftsmen produce precision-forged step shafts with dimensional uniformity that other shops can only achieve by rough machining.

Reduced Costs & Materials

In addition, our step shaft forging capabilities provide significant cost and material savings when compared to machining a bar to a stepped shape. We can supply step shafts and spindles precision-forged with allowance or rough-machined, which can also include drilling or boring.

Step Shaft & Rotor Shaft Process Highlights

The process begins when an entire piece is forged to the major diameter and a fuller tool is used to mark the next step. Then we forge that next step to a smaller diameter or taper to create a contour, while maintaining directional grain flow, thereby giving the part greater strength and fatigue resistance.

Depending on the configuration of your part, our Clinton, Wis. and Spring Grove, Ill. plants can forge custom flanged-end shafts with heads that are upset in a variety of shapes, including single, tapered or multiple-diameter.

Scot Forge Difference

At Scot Forge, we know the importance of getting your parts on-time, as expected. However, for customers new to procuring forgings, ordering a forging that will meet all specifications for end-use applications may be a challenge, which is why finding a trusted supplier and partner is essential. Our employee-owners are here to ensure your project stays on track with our forgings by offering:

Pro Tip - Did you know near-net shapes can save you time and money? Oftentimes, a customer calls to order a disc, which they will later machine down to a more shaped part. By working with our technically trained sales team you can get as close to your finished product shape as possible to optimize your production process.
