manUFACTURING & QUALITY CONTROL

1.Precision Grinding

1.Precision Grinding

Precision grinding utilizes advanced abrasive wheels to refine bearing surfaces, achieving tight dimensional tolerances and superior finishes that ensure our critical industrial components operate with maximum smoothness and long-term reliability.

2. bearing VISUAL INSPECTION

2. VISUAL INSPECTION

Visual inspection is a vital non-destructive quality control method. It examines bearing surfaces with optical aids to detect defects like cracks or scratches, guaranteeing every product meets strict international manufacturing standards.

3. bearing DIMENSIONAL INSPECTION

3. DIMENSIONAL INSPECTION

Dimensional inspection verifies a bearing’s physical features using precise tools like CMMs. This critical quality control process ensures every component strictly matches engineering design specifications for perfect fit and optimal performance.

4. bearing profile measurement

4. profile measurement

Profile measurement evaluates the precise surface contour and cross-sectional shape of bearing components. It captures detailed geometric variations to ensure parts meet specific tolerances and roughness standards for high-precision industrial applications.

5. BEARING ASSEMBLY

5. BEARING ASSEMBLY

Bearing assembly precisely fits inner and outer rings, rolling elements, and cages. Strict cleanliness and accuracy ensure the final bearing unit operates smoothly, delivering exceptional performance and extended service life.

6. bearing Z&V GRADE TESTING

6. Z&V GRADE TESTING

Z&V grade testing evaluates bearing vibration and noise levels. It classifies units into specific quality grades like Z1 and V1, ensuring they meet the strict smoothness and quietness standards for various applications.

7.bearing Ultrasonic cleaning

7. Ultrasonic cleaning

Ultrasonic cleaning uses high-frequency sound waves to generate microscopic bubbles that implode. This dislodges dirt, grease, and contaminants from complex bearing surfaces, ensuring a thoroughly precise and contaminant-free clean.

8. GREASING &anti-RUST TREATMENT

8. GREASING &anti-RUST TREATMENT

Greasing and anti-rust treatment applies specialized lubricants and protective coatings to bearings. This minimizes friction, blocks moisture and oxygen, and effectively prevents corrosion to ensure long-term durability and reliable industrial performance.

9. bearing FINAL RANDOM INSPECTION

9. FINAL RANDOM INSPECTION

Final Random Inspection (FRI) is the last quality check before shipment. Random sampling verifies that finished bearings meet all specifications, guaranteeing the overall batch quality is fully acceptable for delivery.

10. PACKAGING bearing

10. PACKAGING

Packaging is the final manufacturing stage, involving careful wrapping and boxing of bearings. It protects products from damage, moisture, and contamination during transit, ensuring they arrive safely at their global destination.
