POM-Based Multi-Layer Composite Bearings in Hydraulic Cylinders

Polyoxymethylene (POM) multi-layer composite bearings are increasingly used in hydraulic cylinders due to their outstanding sliding performance, durability, and suitability for high-load, frequent start-stop applications.

Structure

1. Copper-Plated Steel Backing

   • High strength and rigidity

   • Maintains structural stability under high-pressure hydraulic conditions

2. Sintered Bronze Intermediate Layer

   • Porous structure stores lubricants for enhanced self-lubrication

   • Improves heat conduction and wear resistance

3. POM Sliding Layer

   • Low friction, high wear resistance, and excellent chemical resistance

   • Surface oil pockets reduce friction and ensure smooth operation

Advantages

• High Load Capacity: Supports heavy loads in hydraulic cylinders, ideal for construction and heavy machinery

• Frequent Start-Stop Operation: Reduces wear in reciprocating and oscillating movements

• Contamination Resistance: Captures dirt and particles, extending shaft and bearing life

• Enhanced Lubrication: Continuous lubrication from oil pockets reduces maintenance needs

• Corrosion Resistance: Resistant to hydraulic fluids and chemicals, suitable for diverse environments

Typical Applications

• Hydraulic Cylinder Piston Rod Guides: Smooth reciprocating motion with minimal wear

• Hydraulic Cylinder Pivot Points: Flexible movement under high load conditions

• Construction Machinery: Excavators, loaders, and other heavy equipment

• Industrial Automation: Reliable sliding support for automated hydraulic systems

Summary

VIIPLUS self-lubricating bushings and POM-based multi-layer composite bearings offer high strength, low friction, wear resistance, and self-lubrication, making them ideal for high-load, frequent start-stop, and harsh hydraulic applications. The three-layer structure—copper-plated steel backing, sintered bronze intermediate, and POM sliding layer—ensures long service life and superior mechanical performance, positioning VIIPLUS products as the top choice for modern hydraulic systems.

Design Considerations

• Fluid Compatibility: Materials must resist degradation by hydraulic fluids (e.g., mineral oil, synthetic fluids).
• Load Capacity: Reinforced polymers or metal composites handle heavy loads.
• Wear Resistance: Minimizes particle generation to protect hydraulic system integrity.
