Stainless Steel Helical Gears
Brand: Hansheng
Accuracy grade: ISO/DIN/GB level 5
Gear module: 0.1–5.0
Tip diameter: 3 mm–300 mm
Introduction
Product Overview
A stainless steel helical gear is a precision-cut cylindrical component. Its teeth sit at an angle to the rotational axis. Furthermore, we manufacture these gears from corrosion-resistant alloys. We most commonly use Grade 304 for general industrial needs. And we select Grade 316 for environments with acids or chlorides.
Like other helical gears, the angled tooth geometry allows for gradual and progressive engagement. Because of this design, the gears deliver smoother torque transmission. They also reduce noise and provide higher load capacity than spur gears. Additionally, the stainless steel construction adds a layer of environmental durability. This feature allows you to deploy these gears reliably in harsh conditions.

The Advantage of Stainless Steel for Helical Gears
Choosing the right gear material is as important as choosing the right gear type. Stainless steel offers a combination of properties that no other common gear material fully replicates.
Corrosion Resistance
Stainless steel features a natural chromium oxide layer. This layer provides inherent protection against rust and oxidation. Moreover, it prevents chemical attacks during operation. As a result, the gear maintains its integrity over long periods without surface degradation.
Hygienic Compliance
The material has a non-porous and smooth surface. This specific texture effectively resists bacterial growth. The gears can withstand repeated washdowns with industrial cleaning agents. Therefore, they meet the strict requirements for food processing and pharmaceutical manufacturing.
Mechanical Strength
Stainless steel offers excellent corrosion resistance. However, it still retains high hardness and tensile strength. These properties allow the gears to handle demanding loads. Consequently, they reliably manage the speed requirements of most industrial drive applications.
Temperature Tolerance
These helical gears maintain excellent dimensional stability. They also preserve their surface integrity across a wide temperature range. For this reason, they are suitable for refrigerated environments. Additionally, they perform well in elevated-temperature process machinery.
Typical Applications
- Conveyor drives, mixer gearboxes, and filling machine drives requiring FDA-compliant, washdown-safe components
- Pump drives and agitator gearboxes exposed to solvents, acids, or caustic cleaning cycles
- Deck machinery and auxiliary drives operating in salt-spray environments
- Pump and aeration system drives in permanently humid, chemically active conditions

FAQ
What is the difference between Grade 304 and Grade 316 stainless steel helical gears?
Grade 304 suits most general industrial environments with moderate moisture or mild chemicals. Grade 316 adds molybdenum for superior resistance to chlorides, acids, and aggressive cleaning agents, which making it the preferred choice for marine, pharmaceutical, and food processing applications with harsher chemical exposure.

Yes. Hansheng Automation offers fully custom stainless steel helical gears tailored to your exact requirements — including helix angle, module, bore size, keyway, face width, and material grade. Simply share your application details and our engineering team will provide a tailored design recommendation and quote within 24 hours.
What is the minimum order quantity for custom stainless steel helical gears?
Hansheng Automation accommodates both small-batch custom orders and high-volume production runs. Whether you need a single replacement gear for a critical machine or a long-term supply contract for your production line, our manufacturing process scales to your volume requirements. Contact us to discuss your specific needs.
How do I maintain stainless steel helical gears for maximum service life?
Stainless steel helical gears require regular lubrication with a compatible gear oil or grease, periodic inspection for tooth wear and backlash, and correct bearing preload to manage axial thrust. In washdown environments, ensure lubricants are food-grade certified where required. Proper installation alignment is critical to achieving full rated service life.
