Mining and metallurgy

High-performance self-lubricating bushing and bearings are trusted by construction & mining companies to perform in the most rugged, demanding environments.

COPPER BUSHING
Providing the world with a sustainable supply of copper bushing & bearings.

Wrapped BronzeBushings and Cast Bronze Bearings made from viiplus’s high strength, and lightweight.

CuSn8 or CuSn6 bronze material for wrapped bronze bushing and C86300, C93200, C95400 solid bronze bearing with lubricating or groove design, has been proven to outperform other materials, even under the harshest of conditions. Construction and mining customers rely on viiplus to meet their mining, construction, and manufacturing equipment needs.

Solve a recurring problem with steel sleeve bushings on continuous mining
machines, Mining Machinery company switched the bushing material to
viiplus Performance CuSn8 or CuSn6.5 wrapped bronze bearings.Since then, there
have been no bearing failures, premature wear of
their Mining Machinery Equipment.

MEETING THE CHALLENGES OF THE MINING EQUIPMENT MARKET

With extensive self-lubricaing material research and lab testings, we had gradually increased its range through actual life cycle testing in the mines with its mining contractors. viiplus can be proud to say that our bearings often proved to work better with extended lifetime results.

VIIPLUS also prides itself to come up with bearing solutions with the change of materials or a complete re-design of genuine bearings if they prematurely fail, causing unnecessary and expensive downtime to the operator. viiplus also started to develop more complex and multi parts arrangements like the Pin Boogie for the undercarriage of larger Dozers and moving further into the development of undercarriage spring coils.

We have been in the dry bushings materials business for many years.

Viiplus’s wide range of high-performance alloys have helped manufacturers and owner/operators increase their productivity and reduce downtime in the following markets:

• Heavy equipment
• Mining equipment

Viiplus are ideal for use in surface and underground mining, construction and heavy manufacturing equipment due to their unique combination of properties including:

• High strength  
• Low friction
• Excellent machinability
• Corrosion, wear, erosion, and galling resistance

Bimetallic bushings, bushings, and thrust gaskets are made of high-quality low carbon steel and sintered bronze powder on the surface. They are suitable for rotating and swinging motion under high load and low speed. With the characteristics of low friction coefficient, good wear resistance, long service life and good anti-bite performance, copper alloy layer can be processed according to the requirements of various types of oil holes and grooves. Products are widely used in mining machinery, steel rolling machinery and so on.
