Let's delve into some of the key cast bronze alloys we offer:
1. C93200 / RG7 / SAE660 / CC493K: The Versatile Workhorse
Often referred to by various designations including RG7 bronze bearings, SAE660, or C93200, this leaded tin bronze (CuSn7Zn4Pb7) is arguably the most common general-purpose bearing bronze alloy worldwide.
Key Properties: Offers an excellent balance of properties:
Very good machining properties.
Good strength and hardness levels.
Excellent wear resistance and anti-friction qualities (enhanced by tin and lead content).
Reasonable corrosion resistance in seawater and brine (not subject to dezincification).
Good dry running properties (especially when graphite plugged).
Pressure-tight characteristics.
Typical Uses: Its versatility makes it ideal for:
General utility bearings and bushings.
Wear plates and thrust washers.
Pump and valve components (housings, bushings).
Water and steam fittings.
Applications with medium loads and speeds requiring adequate lubrication or self-lubrication (graphite plugged).
VIIPLUS Supply: We supply C93200 / RG7 bronze graphite bearings, plain bearings, flanges, wear plates, thrust washers, and custom parts in this alloy.

The Core: Controlled Sintering for Stable Performance
The foundation of many high-performance self-lubricating bearings lies in the sintering process. This involves fusing powdered metals under controlled heat and pressure to create a strong, porous structure that can be impregnated with lubricants or incorporate solid lubricants.
VIIPLUS utilizes dedicated sinter production lines, implementing a scientific and strictly controlled sintering process. Procedures are carefully monitored at every stage to ensure the resulting self-lubricating bearings strips and sheets exhibit stable performance characteristics vital for reliable operation and the successful development of new products.
Automation for Efficiency and Precision
To further enhance quality and efficiency, VIIPLUS incorporates advanced automation into its production flow:
Automatic Forming Machine: This technology plays a key role in shaping the sintered materials into precise bearing forms. Its implementation significantly reduces labor intensity, boosts overall self-lubricating bearings production efficiency, and critically, improves product quality and consistency from batch to batch.
Automatic Chamfering Machine: Precision finishing is crucial. The introduction of automatic chamfering machines refines the production rhythm, greatly improving production efficiency. Furthermore, it leads to a significant improvement in the length accuracy of the final product and ensures angles are finished more cleanly and beautifully.
Uncompromising Quality: Final Inspection and Monitoring
Quality control is not an afterthought; it's integrated throughout our process. VIIPLUS employs strict inspection procedures and inspection standards:
Performance Inspection & Monitoring: The properties of the self-lubricating bearings strips are rigorously tested and monitored.
In-Process Quality Control: Checks are performed during manufacturing stages.
Final Inspection: Every batch undergoes a thorough final inspection before shipment.
This multi-layered approach ensures that product performance and critical tolerances consistently meet or exceed customer requirements.
Driving Innovation Forward
Our commitment doesn't stop at current production. The development team at VIIPLUS continues to actively study new self-lubricating materials and design innovative bushing products to meet the evolving needs of various industries.
