Viiplus offers a sustainable supply of copper bushings and bearings, including wrapped bronze bushings made from high-strength, lightweight CuSn8 or CuSn6 bronze, and solid bronze bearings like C86300, C93200, and C95400, featuring lubricating or groove designs. These products have proven to outperform other materials, even in harsh conditions. Construction and mining customers depend on Viiplus for their equipment needs. For instance, a mining machinery company replaced steel sleeve bushings on continuous mining machines with Viiplus Performance CuSn8 or CuSn6.5 wrapped bronze bearings, resulting in no bearing failures or premature wear since the switch. 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

Through extensive research and lab testing of self-lubricating materials, we have successfully increased their performance through real-life cycle testing with mining contractors. Viiplus takes pride in our bearings, which often demonstrate extended lifetimes.

We also excel at creating bearing solutions by modifying materials or completely redesigning genuine bearings to prevent premature failures that result in costly downtime. Additionally, we are developing more complex multi-part arrangements, such as the Pin Boogie for larger dozer undercarriages, and advancing our work on undercarriage spring coils. For parts development and special bushing sizes, please refer to our Plain Bearing Catalogue for standard mining parts. We have years of experience in dry bushing materials.
