Overview
The HKK Chain 40-1R SSS is a premium single-strand roller chain designed for industrial automation and mechanical power transmission applications requiring corrosion resistance. Manufactured from 304 series stainless steel, this chain is built to withstand harsh environments, extreme temperatures, and moisture exposure. The 20-foot length includes one connecting link for quick installation, making it a drop-in solution for machinery running in food processing, chemical plants, marine equipment, and other demanding industrial settings.
Key Features
- 304 Stainless Steel Construction: All components—link plates, rollers, bushings, and pins—are 304 stainless steel for maximum corrosion and temperature resistance
- Solid Rollers & Bushings: Cold-forged solid construction prevents splitting and deformation under extreme loads and temperature swings
- Shot-Peened Design: Rollers, bushings, and link plates are shot-peened to reduce fatigue stress and extend service life
- ANSI B29-1 Compliant: Meets standard dimensional tolerances for interchangeability with compatible sprockets and drive systems
- Connected & Ready: Includes one connecting link per 20 feet of chain for immediate installation
- Made in Japan: Engineered and produced to HKK’s precision manufacturing standards
