Buying Guide

Match sprocket bore to your shaft

Confirm the sprocket bore (examples here include 5/8" and 1") matches your conveyor shaft or can be adapted with a bushing or keyway to ensure a secure fit

Choose the correct chain size and tooth count

Select a sprocket rated for your roller chain size (e.g., #35, 40B) and tooth count that maintains proper chain wrap and speed ratio for your conveyor layout

Prioritize material and heat treatment

Look for sprockets made from hardened steel or heat-treated alloy when handling heavy loads or abrasive environments to minimize wear and elongation

Consider bore mount type and keyway options

B-type sprockets and various bore diameters are common; verify keyway, set-screw, or tapered-bush mounting options to simplify installation and torque transmission

Balance value with user-rated reliability

Compare brands and user ratings to gauge long-term reliability—options in this list show solid ratings around 4.4–4.6★, indicating consistent performance for conveyor uses
