BS Single Pitch PC Chain

Tsubaki BS Single Pitch PC Chain

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 BS standard roller chain) and lightweight (50% lighter than BS 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.
