Wrapped Bronze Bearings

Wrapped bronze bearings are ideal for applications where there are high levels of contamination. Their running surface is provided with diamond-shaped lubrication pockets or a hole pattern. The lubrication pockets must be filled with grease when the bearing is installed. The wrapped bronze bearings are produced according to the ISO 3547. The AST090 Series Bushings are wrapped of a cold formable homogenous bronze (CuSn8), which will obtain exceptional material properties. The standard sizes are fitted with diamond shaped lubrication indents on the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film in the startup movement and subsequently reduce the startup friction. The material is suitable for the construction and agriculture industries where high load and slow movement are occurring. Advantages of wrapped bronze bearings The main advantages of wrapped bronze bearings include: Long service intervals Not affected by impurities Suitable for corrosive environments Suitable for impact loads and vibrations at low speeds Good heat dissipation Applications of wrapped bronze bearings Wrapped bronze bearings are especially suited to severe operating conditions where frequent maintenance is not possible. Common applications are: Agricultural vehicles Lifting gear Offshore Excavators
