Copper sleeves and steel sleeves are commonly used as a means of protecting and securing cable connections, as well as for reducing electrical noise in high frequency applications. Both materials have their own advantages and disadvantages, which must be taken into consideration when deciding which material is best suited for a particular application.

Copper sleeves are a popular choice due to their excellent electrical conductivity, which makes them ideal for reducing electrical noise in high frequency applications. They are also corrosion-resistant and have a high resistance to wear, making them ideal for use in harsh environments.

Steel sleeves are a popular choice for their strength and durability. They are typically made from high-quality steel alloys, which provide excellent resistance to corrosion, wear, and other types of damage. Steel sleeves are also commonly used in high-temperature applications, where they provide excellent protection against heat-related damage.

When deciding between copper sleeves and steel sleeves, it is important to consider the specific requirements of the application, such as the frequency of use, the operating temperature, and the potential exposure to harsh environments. Additionally, the cost of the sleeves, as well as the ease of installation and maintenance, should also be taken into consideration.

In summary, both copper sleeves and steel sleeves have their own advantages and disadvantages, and the best material for a particular application will depend on the specific requirements of the application. It is important to consider all factors and make an informed decision when choosing between these materials.

　　Bimetal Bushing aluminum-tin alloy (AlSn20Cu) as a sliding layer. In order to improve tribological behavior the sliding layer can be machined with lubricating grooves for oil- or grease storage and distribution. In case of corrosive environment the backing can be tin plated.Bimetal Bushing, wrapped bushes, thrust washers and bushes in connecting rods of gas engines, etc.

MATERIAL AND COMPOSITION

Material Steel+AlSn20Cu

It has fairly good performance in anti-fatigue and good load capacity, anti-corrosion and smooth sliding movement. Sliding layer can be machined with lubricating grooves and/or with grease indents

Aluminum-tin alloy for hydraumatic applications.

BEARING PROPERTIES

• Liner material: AlSn20Cu
• Load capacity: 30N/mm2
• Temperature Max: 150℃
• Liner hardness: HB30~40

AVAILABILITY

Bimetal Bearing forms available in standard dimensions. Metric bearings and imperial bushings made to order: standard bushing forms in special dimensions, half-bushings, special shapes obtained by stamping or deep drawing, customized bushing designs

SHAPES & FORMS

• Cylindrical bushes
• Flanged bushes
• Thrust washers
• Flanged washers
• Sliding plates

ASSEMBLY ADVISE

Housing: Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment Shaft: Chamfer 5 mm x 15°, for easy insertion of the shaft

VIIPLUS advises to use a force fitting mandrel for the installation of the bushing. It might be necessary to apply some grease on the outer surface of the bushing when press fitting it into the housing.

Freeze fitting is suitable for diameter > 130mm, dry ice or liquid nitrogen can be used.

RANGE OF APPLICATION

It usually used as engine bearing with middle or low power, air compressor bushing. It is a good substitution for Babbit material.
