Product Overview

This precision stepped shaft is a multi-diameter, CNC-turned component designed to transmit torque, locate bearings, and align rotating assemblies with high concentricity. Each diameter step, shoulder, keyway and thread is machined to tight tolerance so the shaft fits reliably into gearboxes, motors, pumps and automation equipment.

The core of this product is its material and processing quality. We start from certified bar stock — stainless steel, alloy steel, brass or engineering plastic — and hold diameter tolerances down to ±0.005 mm, concentricity within 0.010 mm, and a surface finish as fine as Ra 0.4 µm on bearing journals. Every shaft is inspected before shipment.

Key differentiator: We control the full chain — material selection, turning, grinding, heat treatment and surface finishing — so shoulder squareness, run-out and fit are guaranteed, not left to chance.

Key Features & Highlighted Advantages

Step Accuracy

Precision Shoulder Faces

Each shoulder is turned square within 0.01 mm perpendicularity, giving bearings and gears a flat, positive seating face under load.

Bearing Fit

Ground Journal Diameters

Bearing seats are cylindrical-ground to h6/g6 fits with Ra 0.4 µm, ensuring smooth rotation, minimal vibration and long bearing life.

Torque Transfer

Keyway & Spline

CNC-milled keyways and splines with tight width tolerance transmit torque without backlash or key deformation.

Assembly

Threaded & Chamfered Ends

Rolled or cut metric / UNC threads with protective chamfers and center holes for easy, damage-free assembly.

Strength

Heat-Treated Core

Optional hardening, carburizing or nitriding delivers a hard, wear-resistant surface over a tough, shock-absorbing core.

Corrosion & Finish

Plated / Stainless Surface

Stainless grades or zinc / nickel plating resist corrosion and wear, with polishing available for a premium finish.

Materials We Can Process

Beyond stainless and alloy steel, our turning and milling lines handle a broad portfolio of materials, so the shaft can be matched to strength, corrosion, weight or cost requirements.

Category Materials Typical Use
Stainless Steel 304, 316, 303, 17-4PH Corrosion-resistant shafts
Carbon / Alloy Steel 1045, 4140, 42CrMo, 20CrMnTi High-strength drive shafts
Non-Ferrous Metals Brass H59/H62, Aluminum 6061/7075, Copper Lightweight / conductive parts
Exotic Metals Titanium, Tool Steel, Hardened Alloy High-wear / high-load applications
Engineering Plastics POM, Nylon (PA), PEEK, PTFE, ABS Light-duty, non-magnetic parts

FAQ — 5 Frequently Asked Questions

1. What material is the stepped shaft made of, and can it be customized?
The default material is stainless steel 304/316, but the shaft is fully customizable — we also machine 1045 carbon steel, 4140 alloy steel, brass, aluminum, titanium and engineering plastics. Choose the material based on your load, corrosion and weight requirements, and we will recommend the best grade.
2. What are the standard dimensions, and can you produce custom sizes?
Our reference range covers shafts from roughly Ø8 mm to Ø35 mm across 2–3 steps, with lengths from 120 mm to 320 mm (see table above). These are indicative only — every shaft is made to order. Send a 2D drawing or 3D model (STEP/IGES) and we will machine to your exact step diameters and lengths.
3. What tolerances and surface finishes can you achieve?
We hold diameter tolerances down to ±0.005 mm on ground journals, concentricity / run-out within 0.010 mm, and surface roughness from Ra 0.4 µm to Ra 1.6 µm. Shoulder faces are square within 0.01 mm. This level of accuracy supports precision bearing and gear fits.
4. Can you work with other materials and add heat treatment or coatings?
Yes. In addition to steel and stainless, we process brass, aluminum, titanium and engineering plastics. We can also add heat treatment (hardening, carburizing, nitriding) and surface finishing (zinc/nickel/chrome plating, black oxide, anodizing, polishing) to match your performance and appearance needs.
5. What is your MOQ, lead time, and how do I request a quote?
Low MOQ from 1 pc for prototypes with flexible volume pricing for production. Typical lead time is 5–10 working days for prototypes and 15–25 working days for mass production, depending on material and finishing. Send your drawing and quantity to receive a detailed quotation within 24 hours.
