ANSI PC Chain

Tsubaki ANSI PC Chain

The pins and pin link plates of these chains are made of SUS304 (spring clips SUS301). Engineering Plastic (white) is used for the inner link. This combination makes it a lube-free, low noise (5 dB lower than ANSI standard roller chain) and lightweight chain (50% lighter than ANSI standard roller chain). Working temperature range: -20°C to +80°C. For details on corrosion resistance, please check out our Corrosion Resistance Guide.
