MCC is pleased to announce that its newly developed Engineered Plastic Bushing Side-Bow Chain (PNB Side-Bow Chain) has officially been granted patent protection.
Patent – Engineered Plastic Bushing Side-Bow Chain


This patented design incorporates an engineered plastic bushing inside the conventional steel bushing structure. Through extensive testing and optimization, MCC successfully achieved a balance between side-flexing performance, wear resistance, and chain strength.

Key benefits of this patented technology
- Reduced lubrication requirements
- Improved wear resistance
- Lower operating noise
- Reduced contamination caused by lubricant splashing
- Lower maintenance requirements for conveyor systems
The technology is particularly suitable for curved conveyors, packaging machinery, automated production lines, and other material handling applications requiring long operating hours and reliable performance.
