Overview
The HKK Chain 40-1R SSS is a precision 304 stainless steel roller chain designed for high-reliability power transmission in corrosive and extreme-temperature environments. HKK precision stainless steel roller chains are manufactured from 304 series stainless steel, to achieve the utmost corrosion and temperature resistance. This 20-foot assembly contains 480 links and is manufactured in accordance with ANSI B29.1 dimensional standards.
Key Features
- Solid Rollers & Bushings: Equipped with solid rollers which will not split or deform like conventional split rollers under extreme loads and temperatures.
- ANSI B29.1 Certified: Meets industry standards for dimensional accuracy and interchangeability.
- Made in Japan: Made in Japan. Engineered with precision manufacturing and quality control.
- 304 Stainless Steel Construction: Superior corrosion and temperature resistance for food processing, washdown, and chemical environments.
- Superior Fatigue Strength: Engineered for maximum allowable load capacity and extended service life.
- Connecting Link Included: One connecting link is supplied with each 10′ of chain.
