Short Pitch Precision Roller Chains
Transmission Chains for Industrial Applications
When conditions require strength and resistance to fatigue, short pitch precision roller chains fill the need. Our short pitch precision roller chains meet ANSI、ISO and BS standards. Options of simplex, duplex and triplex roller chains are available for different power settings and configurations.
All our pitch roller chains have been shot peened and pre-stretched in the factory to assist compact against fatigue and reduce elongation during operation. Individual request for food grade lubricants can be satisfied.
A series short pitch roller chains conform to the American standards where the thickness of the inner plates and outer plates are the same. This type is especially known for strength and long-lasting characteristics. Various adjustments are made to secure best tensile strength possible. Identify your chain size in the charts below to find the chains suit you best.
