Step Shafts, Eccentric Shafts & Crank Shafts

Advantages of Forged Crank Shafts, Step Shafts & Spindles

Your heavy industrial applications deserve the best in strength and reliability. Our years of custom forging expertise allow us to manufacture custom forged crankshafts to meet the most exacting specifications. At Scot Forge, we produce guaranteed sound-centered forged step shafts, crankshafts 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.

Our skilled craftsmen produce precision-forged step shafts with dimensional uniformity that other shops can only achieve by rough machining. In addition, our extensive on-hand material inventory lets us manufacture your custom forged steel shafts with short lead times, so don't turn to castings or turned bar for your critical projects.

Forged Products

Scot Forge Advantages:

Short times in the industry
Wide range of stainless, carbon, and alloy steels
Milling capabilities that bring the product closer to size at reasonable costs

Testing capabilities to ensure quality and adhere to your requirements
No minimum order quantities for prototypes and short-run situations
Produce sizes that aren’t available in plate or bar stock

Reduced Material & Costs - 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.

Continuous Grain Flow & Improved Microstructure - This means your part will have finer grain size, which will reduce the chance of voids and enhance strength leading to better fatigue resistance.

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 challenging, so 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 your finished product shape as close as possible to optimize your production process.
