Worldwide Standard Chains complying with ANSI, BS and ISO.
The chains not only meet enough the requirements for the strength by ANSI, BS and ISO,
but also provide the world's top class quality.

ANSI Standard Roller Chains

• Uniformity consistent heat treated parts
• Shot-Peened Parts for metal fatigue resistance
• Assembled with Cold Formed Solid Bushing for size 35 and up
• Pre-Stretching eliminating initial stretch
• DID's unique XT-Power Link implemented as D.I.D standard connecting link（Size 50 to 240）
