Introduction: Powering Mining Efficiency with Precision Bronze Bushings
In the demanding world of mining, equipment durability and reliability are non-negotiable. VIIPLUS delivers robust solutions with CuSn8 Flanged Bronze Bushings, specifically designed for mining drill rigs and heavy-duty applications. Crafted from high-performance CuSn8 tin-bronze alloy, these metric large-size bushings combine self-lubrication, corrosion resistance, and unmatched load capacity to thrive in harsh mining environments.
Key Features of VIIPLUS CuSn8 Flanged Bronze Bushings
1. Premium CuSn8 Bronze Alloy
- Wear & Corrosion Resistance: Engineered to withstand abrasive materials, moisture, and chemical exposure in mining operations.
- Self-Lubricating Design: Integrated lubrication holes reduce friction by 40%, minimizing maintenance and downtime.
- High Tensile Strength: Supports extreme loads up to 120 N/mm² static and 40 N/mm² dynamic.
2. Metric Large-Size & Flanged Design
- Stability Under Stress: Flanged construction prevents misalignment in high-vibration drill rigs.
- Custom Sizes Available: Standard metric dimensions (e.g., 275x245x240 mm) or tailored designs for unique machinery needs.
3. ISO3547 Compliance
- Quality Assurance: Manufactured to international standards for consistent performance and safety in critical applications.

| Surface roughness ≤ Ra 0.8 | |||
| PROPERTIES | |||
| Economic solution for bronze bearing application due to a thin wall thickness. High load capability and good stability with low abrasion. Suitable for rough working conditions, good corrosion resistance. Lubrication holes for maximum grease storage and the lowest maintenance intervals. | |||
| RANGE OF APPLICATION | |||
| Agriculture machinery, truck cranes & construction machinery, suitable for impact loads | |||
| MAINTENANCE | |||
| It is a low maintenance bushing material. An initial greasing during installation is necessary, after that periodic greasing with oil or grease is mandatory. The lubrication holes are an excellent lubrication depot and keeping maintenance to a minimum. | |||
| MOUNTING ADVISE | |||
| Housing | Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment | ||
| Shaft | Chamfer 5 mm x 15°, for easy insertion of the shaft | ||
| We advises to use a force fitting mandrel for the installation of the bushing. It might be necessary to apply some grease on the outer surface of the bushing when press fitting it into the housing. | |||
