Phosphor Bronze Bushings

Description

A wrapped bronze bushing is a kind of bushing wrapped by a bronze strip. This type of bronze bearing is made of a 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 a high load capacity and long life. Compared with traditional cast bronze bushing, it is cheaper and more compact.  a wrapped bronze bushing is widely used in hoisting machines, construction machines, automobiles, trucks, machine tools, mineral equipment and etc.

Wrapped Bronze is made completely of bronze, CuSn8. The bushings are produced from strips that are then wrapped and calibrated. The working surface is machined and provided with oil holes all over its sliding surface. These indentations serve as lubricant reservoirs, where the lubricant is initially filled and progressively released during operation.

Application recommendations:

Shaft tolerance e7 – f8

Housing tolerance H7

Shaft roughness Ra, µm 0,4 .. 0,8

Shaft hardness, HB 150 – 400

Viiplus wrapped bronze bushings material

Viiplus wrapped bronze bushings are made entirely of bronze, CuSn8. The bushings are produced from strips which are then wrapped and calibrated.

Wrapped Bronze bushings offer many features and advantages

• insensitive to dirty environments
• resistant to shock loads and vibrations at slow speeds
• good resistance to corrosive conditions

Wrapped Bronze cylindrical bushings are made completely of bronze. They are particularly suitable for applications that must be re-lubricated due to dirty environments. The sliding surface is provided with lubrication pockets which contribute to the enhanced lubrication performance.VIIPLUS offers a full range of both plain and flanged cylindrical bushings in accordance with ISO 3547 and DIN 1494

Lubrication Bushings

Lubrication improves the sliding properties, reduces wear, and prevents corrosion since the metal surfaces of bushing and shaft are separated from each other. VIIPLUS Wrapped Bronze bushings are intended to be lubricated with grease or oil. All commonly used greases can be used. Seals are recommended when the bearing is to be used in an aggressive environment.

Long service intervals under severe operating circumstances.

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.

Maintenance

It is a low maintenance bushing material. An initial greasing during installation is necessary, after that periodic greasing with oil or grease is mandatory. The diamond pockets are an excellent lubrication depot and keeping maintenance to a minimum.

Bronze rolling bearing, tin bronze alloy CuSn8 as the material, the surface rolling rhombic oil hole, since the role of storage grease, it has good fatigue strength and load-carrying capacity, corrosion resistance, wear resistance. Widely used in agricultural machinery, construction machinery, construction machinery and other high-load low-speed occasions.

The bearings are wrapped from a cold formed homogenous bronze (CuSn8) with exceptional material properties. The standard sizes are formed with diamond shaped lubrication indents in the bearing surface. The indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction. These materials are suitable for construction and agricultural machinery applications.

The bearing is wrapped of a cold form able homogenous bronze , which will obtain exceptional material properties. The standard bearing is 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 start movement and there with reduce the start friction. Typical application:widely  applied  in hoisting  machines  and other  construction  machines, automobiles, tractor, trucks,  machines tools and some mineral engines
