Detail Information

About Metric 03B Pilot Bore Sprocket

Metric 03B series chain is the smallest British standard roller chain. High precision tolerance is not only necessary for manufacturing roller chain but also for manufacturing chain sprockets. CTS® pilot bore sprockets are manufactured by state-of-the-art modern equipment with high precision tolerances and are made of high-quality high-strength steel, so our 03B pilot bore sprockets not only perform well but also last longer than other brands of chain sprockets.

For a quotation or other information, please contact us and we will be happy to help you.
