This is a HTD 3M-72 Timing pulley ,according to the customer drawing from Turkey , the Reduction ratio is 47 and module is 1.5. we made the surface finish treatment to improve quality and extend service life . Apart from that the main consideration is about backlash. We made this timing pulley as the smallest backlash as possible. As for the materials, we use steel worm wheel and cast iron for HTD 3M-72 tooth timing pulley with the longer service and minimal wear properties.
