Our Custom Forged Step Shaft are expertly forged from high-quality billets, ensuring a strong and durable product. We employ a specialized "fuller" tool to craft these shafts, gradually forming steps with smaller or tapered diameters. This process results in a contoured grain flow within the metal, significantly enhancing strength and fatigue resistance compared to shafts machined from standard bar stock.

Whether you need round bars, square bars, flat bars, or hex bars, Runchi can produce sound-centered bars from various alloy types, ensuring a superior and longer-lasting product compared to machined or cast parts. From planishing and cutting to heat treating, straightening, machining, and testing, we are committed to delivering consistent, high-quality results with fast turnaround times.

Custom Forged Solution

When it comes to heavy industrial applications, you deserve nothing less than the best in strength and reliability. With years of experience in custom forging, we specialize in crafting custom forged crankshafts to meet the most demanding specifications. At Runchi, we manufacture guaranteed sound-centered forged step shafts, crankshafts, and rotor shafts from both ferrous and non-ferrous materials. Our expertise covers a wide range of dimensions, including round, square, rectangle, or polygonal shapes, concentric or eccentric configurations, and tapers or custom designs.

Our skilled craftsmen create precision-forged step shafts with dimensional uniformity that surpasses what other shops can achieve with rough machining alone. Additionally, our extensive material inventory allows us to produce custom forged steel shafts with short lead times, eliminating the need to turn to castings or turned bar stock for your critical projects.
