The rolled bronze bushing, featuring diamond indents and constructed from CuSn8 and CuSn6.5P materials, is a precision-engineered component designed for optimal performance in metric sleeve applications. The unique combination of these high-quality bronze alloys offers exceptional wear resistance, corrosion resistance, and mechanical strength.

The diamond indents provide enhanced lubrication and wear reduction, ensuring smooth and efficient operation. These indents also improve the bushing's ability to retain lubrication, reducing the need for frequent re-lubrication and extending the bushing's lifespan.

The rolled bronze bushing's metric sleeve design ensures a precise fit within the application, minimizing clearance and maximizing performance. The CuSn8 and CuSn6.5P materials, known for their durability and reliability, are chosen specifically for their ability to withstand high loads and frequent motion.

Wh used in heavy machinery, motor vehicles, or other industrial applications, this rolled bronze bushing with diamond indents offers a robust and long-lasting solution for reducing friction and wear. Its precision manufacturing, high-quality materials, and lubrication-enhancing features ensure reliable and efficient performance in various metric sleeve applications.

Rolled Bronze bushings with Diamond Indents 

Factory customized Copper wrapped bushings

VIIPLUS rolled (wrapped) bushings is produced with diamond-shaped lubrication indents on the bearing surface(s). These bushings are ideally suited for thin-wall applications. The indents provide lubricant reservoirs that allow for excellent and prolonged service.

For applications that are sealed or difficult to maintain, we also manufacture this product with self-lubricating graphite filled diamond or circular indents.

They are light-weight and compact and are available as sleeve bushings, flange bearings, washers and plates. They are produced in both inch and metric sizes.

• Metric Sleeves
• Metric Flanges

Bronze rolling bearing, with tin bronze alloy CuSn8/ cusn6.5p as the material, the surface of the rolling diamond oil hole, plays the role of oil storage, it has good fatigue strength and bearing capacity, corrosion resistance, wear resistance.
Widely used in agricultural machinery, construction machinery, construction machinery, and other high-load low-speed occasions.

Application Characteristics

1. Save a lot of copper material and time of copper sleeve manufacturing:
2. Lightweight and low cost compared with axle sleeve and rolling bearing made by vehicle;
3. Various oil grooves can be processed on the friction surface, and oil holes can store certain grease so that the time of oil filling is 5 times longer than that of a copper sleeve;
4. Extremely high bearing capacity, especially suitable for rough friction surface;
5. High heat dissipation, small expansion coefficient, stable service condition and long service life.
