WB700 is a kind of bushes wrapped by bronze strip. The bronze is made as the particular formulation with high specific and gravity, and on its surface may be incorporated with spherical or diamond shaped indentations or/and oil grooves as required by customers. It is of high load capacity and long life, in place of traditional casting bronze bush. It is more cheap and more compact. It is widely applied in hoisting machines and other construction machines, automobiles, tractors, trucks, machine tools and some mineral engines.
►Possible Applications:
Industrial: Widely used in construction machinery, agricultural machinery and so on.
►Advantages:
1. Lead-free and fully recyclable. Less expensive than machined bushing.
2. Minimal space required.
3. Lighter in weight than machined bushing or roller bearing.
4. High stability under load, therefore particularly suitable for oscillating bearing.
5. Lubrication grooves are coined into the metal, and any shape desired is possible.
6. Grease depots for long-term lubrication.
►Flanged bushing offer the following additional advantages:
1. A single bushing and take both radial and axial forces.
2. A single bearing element is needed to replace both thrust washer and cylindrical bushing.
3. High stability.
4. No fixing of thrust washers.
