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