Buying Guide

Match chain size and pitch

Confirm sprocket pitch (e.g., #35, #40) matches your roller chain to ensure proper engagement and long wear life

Choose the correct bore and keyway

Select the bore diameter (5/8", 3/4", 1") and verify a compatible keyway or set screw option to fit your shaft securely

Pick the right tooth count

Tooth count affects speed ratio and torque; larger sprockets yield lower speed and smoother engagement for chain-driven systems

Consider material and heat treatment

Look for hardened steel or heat-treated sprockets for higher wear resistance in industrial or high-load applications

Check mounting type and B/BD designation

Confirm B-type or BD-type compatibility with your system, as flange and spacing differences affect chain alignment
