Key Features of Outward Wound Brush Spring
Uniform Surface Contact
The outward wound spring structure delivers consistent bristle pressure across cylindrical and irregular surfaces, ensuring even polishing and cleaning results without flat spots .
Flexible Winding Density Options
From closed-coil for aggressive material removal to open-coil for lighter finishing, pitch adjustments allow you to match brush intensity to your specific application requirements .
Durable Spring Core Construction
Reinforced steel or stainless steel spring core offers high elasticity and rotational stability, avoiding deformation at high speeds and extending service life .
Versatile Filament Selection
Available in stainless steel, carbon steel, brass, nylon, and abrasive materials — each offering distinct cleaning intensity and surface finish characteristics for different workpieces .
Material & Technical Specifications
| Material | Hardness | Corrosion Resistance | Heat Resistance | Spark Risk | Best Use |
|---|---|---|---|---|---|
| Stainless Steel | High | Excellent | High (800°C) | Low | Polishing, food-grade, high-temp environments |
| Carbon Steel | High | Poor | Moderate | High | Heavy descaling, aggressive rust removal |
| Brass | Medium | Good | Moderate (300°C) | None | Soft metals, explosion-proof areas |
| Phosphor Bronze | Medium-High | Very Good | Moderate | None | Marine, electrical, non-ferrous polishing |
| Galvanized Steel | Medium-High | Good | Moderate | High | Light descaling, cost-effective option |

Filament Material
Stainless steel for corrosion resistance, carbon steel for aggressive cleaning, brass for non-sparking, or nylon for gentle treatment. Material affects cleaning intensity and finish.

Winding Configuration
Outward-facing bristles polish flat sheets and cylindrical parts. Inward-facing bristles clean rods and tubes passing through the center. Configuration determines contact method.

Dimensions & Spring Pitch
Customize inner/outer diameters, coil length, and spring pitch (closed for density, open for flexibility). Core: galvanized or stainless steel.

Mounting & Special Features
Mounting: slip-on, bolt-on, welded, or hub. Adjust trim length for flexibility. OEM support includes sample production.
