Multi-Functional Stainless Steel Shaft
Made of hardened stainless steel, lowering the risk of getting deformed, grooved, or nicked by the bearing balls or rollers. Available in 4 mm, 8 mm, 10 mm, 12 mm, 16 mm, and 20 mm diameters.
Made of 316L stainless steel. Excellent corrosion resistance, relatively lightweight. Coarse thread on the bottom and partly black oxide surface.
Made of 316 stainless steel. The stainless steel hollow shaft is weight-saving, high-strength, and high-rigidity. It also has advantages in the motor system with high speed, lower rotational inertia, and compact design.
The stainless steel keyed shaft provides a positive locking function, which is suitable for machinery that requires low torque. Easy to replace.
Designed with multiple teeth, the stainless steel spline shaft distributes force evenly across the shaft, providing a smoother and quieter torque transmission, as well as a longer service life.
Made of food-grade 316L stainless steel. The stainless steel mixer shaft features excellent corrosion resistance and is easy to maintain. It can handle a wide range of viscosities and complex materials.
Made of 316L stainless steel. The stainless steel propeller shaft features excellent corrosion resistance. Chrome-plated, it can absorb the impacts from roads, air, or water, making it suitable for various applications such as boats and cars.
This stainless steel eccentric shaft converts rotary motion into linear reciprocating motion. Excellent corrosion resistance. Suitable for both engine systems and machinery systems.
Material Selections
The materials are available in SS 303, SS 304, SS 304L, SS 304H, SS 310, SS 310S, SS 310H, SS 316, SS 316L, SS 316H, SS 316Ti, SS 317, SS 317L, SS 321, SS 321H, SS 347, SS 347H, and SS 904L. The most favourable types of stainless steel for manufacturing shafts are SS 303, SS 304, and SS 316 due to their superb strength and corrosion resistance. Or if you have special material needs for your project, please let us know in advance.
Finishing Surface Treatments
According to your requirements for the surface finish, color, and oxidation treatment of stainless steel shafts, we can provide you with various surface treatments to meet both the functional and aesthetic purposes. Below are the typically customizable options:
Colored zinc plate: It can corrode earlier than stainless steel, providing a longer service life and a wide range of color options for your stainless steel shaft.
Sandblasting: It effectively removes the oil, dust, rust, and other contaminants, providing your stainless steel shaft with an even, smooth surface, better wear resistance, and making it easier to be coated.
Passivation: Removes free surface iron and other contaminants, allowing a thicker, more uniform, and more protective chromium oxide layer to form.
CNC precision grinding(machinery polishing): CNC precision grinding makes the surface smoother and gives it a certain glossiness.
Typical Applications of Stainless Steel Shafts
- Aerospace industry
- Automotive industry
- Electronics
- Heavy Machinery Industry
- Mechanical Manufacturing
- Oil and Gas Industry
Stainless steel is recognized as one of the most suitable materials for manufacturing shafts. This is because:
Shafts are often used in engines and mechanical motion structures, where the environment is filled with oil, steam, and various corrosive substances. Stainless steel has excellent corrosion resistance, which can greatly increase the service life of the shaft and greatly reduce the risk of failure of mechanical equipment.
In addition, stainless steel also has excellent load strength and mechanical strength, and is an ideal choice in heavy-duty machinery.
The material selection of shafts in food processing and pharmaceutical industries needs to take into account both efficiency and hygiene. Stainless steel is easy to clean and has excellent antibacterial properties, which meet the industry’s strict hygiene standards.
What’s more, stainless steel has excellent temperature adaptability and can maintain its own characteristics in most high and low temperature environments, allowing the shaft to be used in harsh temperature environments.
It depends. If your project requires a stainless steel shaft with extreme wear resistance, then 400 series stainless steel is your best choice, but 400 series stainless steel will be less corrosion resistant than 300 series stainless steel.
If your stainless steel shaft is used in a harsh, corrosive environment (such as ship engines, petrochemical machinery, etc.), 316L stainless steel with its excellent corrosion resistance will be your best choice.
If your project does not have the above extreme corrosion resistance or wear resistance requirements, and you need a more cost-effective type of stainless steel, 304 stainless steel may be the best option for your project.
Most stainless steels, due to their exceptional strength, can withstand the stresses of CNC machining.
The biggest advantage of CNC machining stainless steel shafts is that, through programming, CNC machining centers can mill, turn, drill, and grind stainless steel shafts with high precision, achieving a tolerance of ≤ ±0.01 mm and high consistency in mass production.
The function of the spline stainless steel shaft and key shaft is to realize the linkage between the shaft and other parts. However, the tooth and flange design of the spline shaft can better distribute the circumferential stress to adjacent components in high-speed running machinery, thereby extending the service life of parts. Furthermore, it does not cost much to replace keyed shafts with splined shafts, and therefore, splined shafts are replacing keyed shafts in various applications.
