Overview
The HKK Chain 35-2R is a premium duplex riveted roller chain engineered for reliable power transmission across industrial machinery and mechanical drives. With 320 links spanning 10 feet, this chain meets ANSI B29.1 standards and delivers the high strength and durability HKK is known for. The 35-2R configuration features a 3/8″ pitch and is manufactured from high-quality carbon steel with cold-forged solid bushings.
Key Features
- Superior Capacity Plus™: 810 lbs maximum allowable working load—30% higher than standard ANSI 35 chains
- High Tensile Strength: 4,800 lbs average ultimate strength for demanding applications
- Duplex (2-Strand) Design: Increased load capacity and power transmission capability
- Cold-Forged Solid Bushings: Minimize elongation and wear, extending chain life
- Heat-Treated Components: Shot-peened link plates, bushings, and specially treated pins for fatigue resistance
- Connecting Link Included: One full-strength connecting link supplied with the 10 ft chain
- Made in Japan: Manufactured to HKK’s rigorous quality standards
