RS Roller Chains from U.S. Tsubaki are designed to last longer for cost-effective, maximum performance. When you choose RS Roller Chain, you get much more than ANSI Standards: • 25 percent higher horsepower ratings to give you more power in the plant and to handle variable shock loads.
• 30 percent longer wear life in nonlubricated applications (pre-lube only), driving down your replacement and maintenance costs. • Increased shock resistance and higher tensile strength for long-lasting performance in the most demanding conditions.
