CNC Machined Motor Shaft

-- Steady & Reliable Manufacturer --

A CNC machined motor shaft is the central rotating component of an electric motor, transferring mechanical torque from the rotor to the driven load. At Changzhou Fenglan, we manufacture motor shafts from raw bar stock through to finished, inspection-passed components — all under one roof. Our range covers diameters from 4 mm to 120 mm and lengths up to 3,000 mm, in materials including carbon steel, alloy steel, stainless steel, and aluminum.

Whether you need a standard stock shaft for a replacement application or a fully custom OEM shaft machined to your CAD drawing, our engineering team handles both with equal precision. Every shaft is dimensional-inspected on a Mitutoyo CMM and ships with a material certificate.

Application

Motor shafts from Fenglan are used across a broad range of industries where reliable rotary power transmission is critical:

Electric motors — AC induction motors, DC motors, servo motors, and stepper motors
Pumps — centrifugal pumps, submersible pumps, chemical dosing pumps
Gearboxes & reducers — input and output shafts for planetary and helical gearboxes
Conveyor systems — drive shafts for belt and roller conveyors
Agricultural machinery — tilling and harvesting equipment drive trains
Fan and blower assemblies — HVAC and industrial ventilation
Power tools — armature shafts for drills, grinders, and saws

Advantage

Factory-direct pricing — no middlemen; competitive unit cost at any volume from 10 to 100,000+ pieces
Full in-house machining — turning, grinding, keyway milling, and heat treatment all performed on-site
Tight-tolerance capability — IT6 as standard, IT5 achievable with SPC control
Material flexibility — stock 10+ grades; custom alloys sourced within 3 days
OEM drawing support — DXF, DWG, STEP, PDF all accepted; free DFM review within 24 hours
Traceable quality — CMM inspection report and SGS mill cert shipped with every order
Short lead times — prototype in 3–5 days; production in 7–15 days

Payment & Shipping

We accept T/T (bank transfer), L/C at sight, PayPal (samples), and Western Union. A 30% deposit is required to confirm production, with the balance paid before shipment.

Standard lead time is 7–15 business days for regular orders; prototype samples ship within 3–5 days. We ship worldwide via DHL, FedEx, UPS, sea freight (FCL/LCL), and air freight. FOB Changzhou and CIF terms are both available. All goods are packed in export-standard cartons with foam padding or wooden crates for heavy items. A commercial invoice, packing list, and COA are provided with every shipment. For large OEM orders, customized packaging and private-label options are available upon request.

Q: What is the standard tolerance for your motor shafts?
A: Our default tolerance is h6/h7 (approximately ±0.008–0.015 mm depending on diameter). For precision servo and spindle applications we can hold IT5 with 100% CMM verification.

Q: Can you produce motor shafts from my drawings?
A: Yes. We accept DXF, DWG, PDF, and STEP files. Our engineers review every drawing for manufacturability within 24 hours and confirm tolerance, surface finish, and material before production starts.

Q: What is the minimum order quantity?
A: MOQ is 10 pieces for standard sizes. For prototype or sample orders we accept 1 piece, with a small tooling/setup fee applied.

Q: Do you offer induction hardening for motor shafts?
A: Yes. We can induction-harden specific zones (typically journal diameters or spline sections) to HRC 48–55 while leaving the rest of the shaft at Q+T hardness for toughness.

Q: What surface treatments are available?
A: Options include centerless grinding (standard), hard chrome plating, black oxide, zinc plating, electroless nickel, and passivation for stainless grades.
