Stainless Motor Housing Manufacturer
Jiangsu Yufeng Electric Co., Ltd. is a professional Stainless Motor Housing manufacturer and supplier based in China. We integrate stamping, welding assembly, machining, and surface treatment into one production system, delivering 304 stainless steel motor housings for demanding environments where corrosion resistance, hygiene, and durability are critical. With 40 years of industry focus and an annual capacity exceeding 5 million units, we support projects from prototype to mass production.
Our stainless housings are engineered for applications in food processing, medical equipment, chemical processing, marine systems, and other harsh operating conditions. The material's inherent resistance to moisture, acids, alkalis, and salt spray ensures long-term reliability without rust or degradation.
Product Range
We offer a focused range of 304SS motor housings, each designed for specific size and mounting requirements. Our current standard configurations include:
| Model | Inner Diameter | Height | Wall Thickness | Key Features |
|---|---|---|---|---|
| Inner Diameter 139 304SS Motor Housing | 139 mm | Custom | 3 mm | Standard cylindrical housing |
| Inner Diameter 160 304SS Motor Housing With Base | 160 mm | 175 mm | 3 mm | Welded base, mirror polish, laser-engraved nameplate |
| Inner Diameter 180 304SS Motor Housing | 180 mm | 320 mm | 3 mm | Reinforced design, lifting lug for heavy motors |
Beyond these standard models, we customize housings to your exact dimensions, mounting configurations, and surface finishes. Our engineering team, with an average of over 20 years of experience, collaborates with you from drawing review to sample development.
Application Fit
Stainless motor housings are essential in environments where standard steel would corrode or contaminate the process. Typical applications include:
- Food & Beverage Processing: Motors driving pumps, mixers, and conveyors that require frequent washdowns and resistance to acidic or alkaline cleaning agents.
- Medical & Pharmaceutical: Equipment demanding hygienic surfaces and easy sterilization, where mirror-polished stainless prevents bacterial growth.
- Chemical & Marine: Pumps, valves, and agitators exposed to salt spray, humidity, and corrosive chemicals.
- Wastewater Treatment: Motors in aeration tanks and sludge handling systems that operate in moist, corrosive atmospheres.
Our 304SS housings are also suitable for new energy vehicle auxiliary motors and special equipment where long-term reliability is non-negotiable.
Material and Specifications
We use high-quality 304 stainless steel, which offers excellent corrosion resistance, high-temperature tolerance, and oxidation resistance. The 3mm wall thickness provides robust structural integrity, resisting compression, impact, and deformation. For applications requiring even higher corrosion resistance, we can discuss alternative grades such as 316L.
Critical specifications we control include inner diameter tolerance, concentricity, surface finish (from brushed to mirror polish), and weld integrity. Our in-process quality checks use custom gauges to monitor these characteristics, ensuring consistency across batches.
Manufacturing and Quality Assurance
Our factory operates with full-process capabilities: coil slitting, stamping, automated welding, precision machining, and surface treatment. For stainless housings, we employ TIG welding to produce clean, strong welds that preserve corrosion resistance. After welding, we offer electrophoretic coating or powder coating for additional protection, or mirror polishing for hygienic applications.
We are ISO 9001:2015 certified and implement a closed-loop quality system. Each batch is traceable to raw material lots, production machines, and operators. We conduct incoming material inspection, in-process checkpoints, and final dimensional verification. For automotive-related projects, we align with IATF 16949 practices to meet stringent requirements.
Customization and Configuration
We understand that every motor design has unique requirements. Our customization options include:
- Dimensions: Inner diameter, height, and wall thickness tailored to your motor stack and frame size.
- Mounting Features: Bases, flanges, lifting lugs, or custom brackets welded or machined as needed.
- Surface Finish: Brushed, mirror polish, or coated finishes to meet hygiene or aesthetic standards.
- Identification: Laser-engraved nameplates for permanent, fade-resistant marking.
- Additional Machining: Holes, slots, or threads for sensors, cable glands, or ventilation.
Our rapid prototyping capability delivers standard custom samples within 3–10 working days, and complex projects within 15 days. This speed supports your R&D and time-to-market goals.
Integration and Installation Support
We provide technical support throughout your project. Our engineers can review your motor assembly drawings to ensure the housing integrates seamlessly with your stator, rotor, and end shields. We consider factors like heat dissipation, mounting orientation, and access for maintenance. For large motors, we can add lifting lugs to facilitate safe handling and installation.
We also provide documentation including material certificates, inspection reports, and dimensional data to support your incoming quality control.
Maintenance and Serviceability
Stainless steel housings require minimal maintenance, but proper care extends their life. Our design facilitates easy cleaning and inspection. For applications with high vibration, we ensure weld strength and structural rigidity to prevent fatigue. We can also supply spare parts or additional housings for field replacements, ensuring your operations continue without prolonged downtime.

FAQs
What stainless steel grades do you use?
We primarily use 304 stainless steel for its excellent corrosion resistance and formability. For more aggressive environments, we can discuss 316L or other grades based on your requirements.
Can you customize the housing dimensions?
Yes, we specialize in custom dimensions. Provide your required inner diameter, height, wall thickness, and mounting features, and we will engineer the housing to your specifications.
What surface finishes are available?
We offer brushed, mirror polish, and coated finishes (electrophoretic or powder coating). Mirror polish is ideal for hygienic applications, while coatings add extra protection.
How do you ensure quality consistency?
We use custom gauges for 100% inspection of critical dimensions, maintain full traceability, and follow ISO 9001:2015 procedures. Each batch is documented for your review.
What is your lead time for samples and production?
Standard custom samples ship within 3–10 working days; complex projects within 15 days. Production lead times depend on order volume and are confirmed with your quotation.
Do you support small batch orders?
Yes, we support multi-variety, small-batch production, ideal for R&D trials and pilot runs. Our flexible manufacturing allows cost-effective small quantities.
