Stainless Steel Flange Shaft With Keyway

Material Grades:

High-grade 304, 316, or 416 Stainless Steel for varying levels of strength and corrosion resistance.

Dimensional Range:

Shaft diameters from 5mm to 100mm, with customizable flange diameters and lengths.

Precision Tolerances:

Achieving h6, h7, or g6 tolerance levels to ensure perfect bearing and coupling fits.

Keyway Precision:

Parallelism and depth are strictly controlled via CNC milling to prevent mechanical vibration and backlash.

Surface Treatment:

Options include passivation (for chemical stability), mirror polishing, or precision grinding (Ra 0.4–0.8μm).

Integrated Design:

The monolithic flange-and-shaft structure offers superior structural integrity compared to multi-piece assemblies, reducing stress concentration.

Optimized Torque Transfer:

Our precision-machined keyways ensure a secure mechanical interlock, critical for high-frequency start-stop cycles in motors and reducers.

Superior Concentricity:

Strict TIR (Total Indicator Reading) controls ensure minimal runout, extending the life of your seals and bearings.

Harsh Environment Ready:

Using 316L stainless steel, our shafts excel in marine, chemical, and food-grade environments where rust and contamination are risks.

Power Transmission:

Electric motors, gear reducers, and hydraulic drive units.

Automated Systems:

Conveyor rollers, robotic arms, and packaging machinery.

Specialized Equipment:

Marine propulsion, pharmaceutical mixers, and food-grade pumps.

Pumping & Valves:

High-pressure fluid systems requiring anti-corrosive drive components.

Strict QC Inspection:

100% dimensional checks using CMM (Coordinate Measuring Machines), hardness testers, and torque analysis.

Full Documentation:

Material mill certificates, inspection reports, and heat treatment logs are provided with every shipment.

Secure Global Logistics:

Products are protected by anti-rust bags and custom foam padding within export-grade cartons to ensure zero-defect arrival.

Fast Lead Times:

Prototype samples in 25 days; bulk production typically completed in 28-35 working days.

Q1:

Can you manufacture shafts based on my custom 2D/3D drawings?

A1:

Yes, we specialize in OEM/ODM services. Simply send us your PDF, DWG, or STEP files for a rapid quote.

Q2:

Which stainless steel grade is best for marine applications?

A2:

We recommend 316 Stainless Steel due to its high molybdenum content, which provides excellent resistance to chloride-induced pitting and corrosion.

Q3:

Do you offer custom keyway dimensions?

A3:

Absolutely. We can machine standard keyways (metric/imperial) or custom slots per your specific coupling requirements.
