Phosphor tin bronze sliding bearing sleeve bronze with oil holes bushing.Phosphor bronze is characterized as a very pure alloy with extremely low content of impurities. Phosphor blends well with copper making the material hardly reacting on oxygen (oxidation).Phosphor tin bronze bushing is an alloy bearing and bushings with high wear resistance and good mechanical properties. There are Flange drawing of standard size inside diameter and outside diameter height different size and wall thicknesses available in phosphor tin bronze sliding bearings.

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.
