Stepped Shaft
Stepped shafts are fundamental components in mechanical engineering, designed to meet diverse assembly and load-bearing requirements. They allow precise positioning of gears, bearings, and other mounted components while optimizing strength and weight distribution. Glory Steel Work manufactures high-quality stepped shafts suitable for a wide range of industrial applications.
What is a Stepped Shaft?
A stepped shaft is a cylindrical mechanical component featuring multiple diameter segments along its length, forming visible “steps.” These steps may increase or decrease in diameter sequentially, and each segment is connected by a flat plane perpendicular to the shaft axis.
Key functions include:
- Precise positioning of components: Gears, bearings, and pulleys are mounted accurately using the step surfaces, preventing axial movement during operation.
- Load optimization: Different diameters accommodate varying torque and bending loads, achieving strength where needed while reducing overall weight.
- Compatibility with multiple components: The stepped design allows different bore sizes to fit directly onto the shaft without additional machining or adapters.
Stepped shafts are widely used in machine tool spindles, automotive gearbox shafts, engine crankshafts, reducer shafts, motor rotor shafts, and other machinery requiring precise torque transmission.
Stepped Shafts We Supply
Glory Steel Work provides stepped shafts in a variety of materials and specifications:
- Materials: Stainless steel, spring steel, cold-drawn steel, hot-rolled steel, forged steel, alloy tool steel, alloy structural steel, carbon tool steel, carbon steel, and bearing steel.
- Dimensions: Diameters range from 250 mm to 800 mm; lengths can be customized per customer requirements.
- Manufacturing & Inspection: Shafts are precision-turned on CNC lathes, followed by grinding for tight tolerances and smooth surfaces. Heat treatments such as annealing, tempering, quenching, or surface finishing are applied. Non-destructive inspection standards include GB/T6402‑91 CLASS 2 or SEP 1921 C/C, D/d.
- Packaging: Available as bare shafts or in seaworthy export packaging.
