CuSn8 Bronze Bearings: VIIPLUS’s Durable, Self-Lubricating Solutions for Industrial Excellence
In the world of heavy-duty machinery and precision engineering, bronze bearings play a pivotal role in minimizing friction, enhancing longevity, and ensuring seamless operations. At VIIPLUS, we specialize in manufacturing premium wrapped perforated bronze bushings crafted from CuSn8 material—a high-performance tin-bronze alloy engineered to excel in demanding environments. Let’s explore why our bronze bearings are the go-to choice for industries worldwide.
**What Are CuSn8 Bronze Bushings?**
CuSn8 bronze bushings are cylindrical components made from a copper-tin alloy (CuSn8), comprising 7.5–8.5% tin, 0.01–0.4% phosphorus, and trace elements like iron, nickel, and zinc. The unique “wrapped perforated” design involves cold-forming a bronze strip into a cylindrical shape, creating a robust structure with diamond-shaped lubrication indents or perforations. These perforations act as reservoirs for grease or oil, enabling self-lubrication and reducing wear during operation.
Compliant with DIN 1494 standards, VIIPLUS’s bushings are precision-engineered for reliability, offering unmatched performance in high-load, low-speed, and corrosive environments.

Product Description
Bushings Plain Bearings and Sleeve Bearings
CUSN8/6.5 is made from high-grade phosphorous tin bronze alloyed bushings. The slide bearings are specially designed to withstand heavy loads and to be shock-resistant. The entire bearing sliding surface consists of lubrication pockets that build up a lubricating film that reduces friction, both at startup and during operation. CUSN8/6.5 BRONZE is intended for radial, oscillating and axial movements and are especially suited for extra high loads. Bronze Bushings take over where other types of bearings break or fail.

Bronze Wrapped Bearing with Oil Pockets(090 CYLINDRICAL BUSHES)
Sliding Bearing 090 caused by chemicals and environments. During the operation, the grease & oil will be released from the Indentations, which allow for long-term lubrication. Compare with Machined bronze bearings; 090 can offer some advantages including thin wall, lower weight, cheaper cost, high load etc. It is suitable for high load, lower speed application like construction, Transport, and agriculture machinery.
The bearings are wrapped from a cold-formed homogenous bronze (CuSn8) with exceptional material properties. The standard sizes are fitted with diamond-shaped lubrication indents in the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of the movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery applications. Bronze Bearings and Bronze Sleeve Bushings made of CuSn8 with Lubrication Indents.
