Product Specification

Precision Sealing Flange | ±0.02mm Tolerance for Motor End Covers

Product Description

Our Precision Sealing Flanges are high-performance structural components specifically designed for the most demanding sealing environments. Primarily utilized as Motor End Covers and Bearing Housings, these parts are manufactured through advanced multi-stage deep drawing and precision metal stamping techniques.

At Xiamen METS Industrial & Trading Co., Ltd., we understand that precision is the foundation of mechanical reliability. Each flange is engineered to achieve a critical ±0.02mm tolerance, ensuring a perfect concentric fit for bearing seats and motor shafts. By utilizing premium materials such as SUS304/316 Stainless Steel and specialized cold-rolled steel, we provide components that offer exceptional airtightness, heat dissipation, and structural rigidity. Whether for micro-motors or industrial-grade pumps, our sealing flanges ensure optimal system performance and a leak-proof operation.

Key Features

• Extreme Precision Control: Industry-leading ±0.02mm tolerance ensures seamless integration with high-speed rotating motor components.

• Superior Deep Drawing Craftsmanship: Seamless one-piece construction via multi-station forming, eliminating weak points and ensuring uniform wall thickness.

• High Concentricity: Precision-engineered central bore alignment to reduce vibration and noise in motor assemblies.

• Advanced Surface Finishes: Options for high-durability Black Powder Coating, Electrophoresis, or Zinc Plating to withstand harsh chemical and thermal environments.

• Optimized Material Integrity: Processed to maintain the metallurgical strength of the steel, providing high resistance to deformation under pressure.

Technical Parameters

FAQ

Q1: How do you maintain a ±0.02mm tolerance in mass production?

A: We utilize high-precision CNC multi-station presses and implement real-time SPC (Statistical Process Control) to monitor critical dimensions throughout the production run.

Q2: Can you provide Sealing Flanges with a specific salt spray resistance?

A: Yes, with our premium powder coating or electrophoresis treatments, we can meet 96-hour to 500-hour salt spray test requirements.

Q3: What drawing formats do you accept?

A: We prefer CAD (.dwg, .dxf), SolidWorks (.step, .igs), and high-resolution PDF files for technical evaluation.

Q4: Do you offer secondary operations like nut welding or tapping?

A: Absolutely. We provide integrated secondary services including tapping, riveting, and automatic nut welding to provide a ready-to-assemble component.
