Meta Title
VIIPLUS Self-Lubricating Bearings | Hydropower & Heavy-Duty Bushing Solutions
Meta Description
VIIPLUS provides self-lubricating bronze bearings with solid lubricant embedded technology for hydropower, gates, valves, and heavy-load applications. Maintenance-free, corrosion-resistant, and high-performance.
VIIPLUS Self-Lubricating Bearing Solutions for Hydropower & Heavy-Duty Industries
In demanding hydropower environments, bearing systems are continuously exposed to water, heavy loads, oscillating motion, and limited lubrication conditions. Traditional lubrication methods often fail due to contamination, washout, or maintenance constraints.
VIIPLUS delivers engineered self-lubricating bearing solutions designed to operate reliably under extreme conditions without external lubrication.
What Is a Self-Lubricating Bearing?
A self-lubricating bearing is a composite material that integrates solid lubricants (such as graphite or PTFE) into a metal matrix. During operation, these lubricants form a transfer film on the shaft surface, reducing friction and wear.
Key characteristics:
- Maintenance-free operation
- Stable performance under boundary lubrication
- Resistance to water, dust, and contaminants
- Long service life in harsh environments
VIIPLUS Core Technology: Solid Lubricant Embedded Bronze Bearings
VIIPLUS specializes in CNC cast and powder metallurgy bronze bearings with embedded solid lubricants.

- Copper-based alloy (CuSnPb or similar bronze systems)
- Embedded solid lubricants (graphite / MoS₂ / PTFE depending on application)
- High-density or porous structures depending on design
Advantages
- Excellent load-bearing capacity
- Low friction without external oil
- Strong anti-seizure and anti-wear performance
