Including A/B Series Roller Chain、A/B Series Straight Plate Roller Chain、A Series Heavy-duty Roller Chain、Single-side Cotter Pin Roller Chain、Double-pitch Transmission Roller Chain、Heady-duty Series Roller Chain、Self-lubrication Roller Chain, etc.

A Series Roller Chain
- High-precision assembling machine, no warp occurred in chain framework, operation noise lower than 50 decibels.
- Imported Taiwan punching machine and multistage progressive die, burnishing band of plate reaching over 90%, ensuring extrusion force
- Ultimate tensile pre-stretching under dual-hydrocylinders, decreasing chain elongation by 30%.
- Wide-waist plate and steel-ball hole burnishing, remarkably improving chain’s anti-fatigue performance, reaching international standard of over 5 million times of fracture limit regarding fatigue resistance under high-frequency loading.
- Plate shot-peening treatment, refining inner microstructure, increasing tensile strength by 15%, which surpasses domestic competitors by 10%.
- Germany-imported environment-friendly super wear-resistant grease, with adhesive thickness over 0.2mm, greatly improving wear-resistance performance.
