Wrapped phosphor tin bronze plain bearings, constructed from CuSn8/CW453K or CuSn6/CW452K alloy, offer exceptional self-lubricating properties and are designed as cylindrical oilless bushings. These bushings are engineered to provide smooth, reliable, and maintenance-free operation in a variety of applications.

The CuSn8/CW453K and CuSn6/CW452K alloys used in these bushings possess high strength, ductility, and corrosion resistance. Their self-lubricating properties eliminate the need for external lubricants, reducing friction, wear, and downtime.

The wrapped design of these plain bearings provides additional durability and stability, while the cylindrical shape ensures precise fit and alignment. These oilless bushings are ideal for use in high-load, low-speed applications where traditional bearings may fail due to insufficient lubrication or high wear rates.

Wrapped phosphor tin bronze CuSn8/CW453K & CuSn6/CW452K self-lubricating plain bearings, cylindrical oilless bushings, offer a cost-effective and reliable solution for applications requiring precision alignment, smooth operation, and long-term durability.

Wrapped bronze bushings are made entirely from phosphor bronze CuSn8. Wrapped Bronze Bearing 090 bronze wrapped bearings Cylindrical Oilless Bushing Sleeve Bushes manufacturer

Bronze bushing is a kind of wrapped self lubricating bearing.VIIPLUS Series bronze bearing is a kind of bushing wrapped by bronze strip. This type of bronze bearing is made of particular formulation with high specific gravity and its surface can be incorporated with spherical or diamond shaped indentations or oil grooves based on customers’ requirements. It is high load capacity and long life. Compared with traditional cast bronze bushing, it is more cheap and more compact. Series wrapped bronze bushing is widely used in hoisting machines, construction machines, automobiles, trucks, machine tools, mineral equipment and etc.

CuSn8P or CuSn6P tin bronze bearing is an economical bearing with high bearing capacity and good wear resistance.The working surface of the product is covered with regular rhomboid oil holes, which play the role of oil storage and can easily form oil film during initial movement so as to reduce initial friction factors.Mainly used in agricultural machinery, construction machinery and other high-load low-speed occasions

Bronze Bearings made of CuSn8 with Lubrication Indents

Bronze Wrapped Bearing with Oil Pockets(090 CYLINDRICAL BUSHES)

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 movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery applications.
