28-3M-09 HTD Pilot Bore Timing Pulley
The 28-3M-09 HTD Pilot Bore Timing Pulley provides highly precise synchronous drive alignment for small mechanical networks. Engineered with a clean 3mm curvilinear pitch tooth profile, it drives a 9mm wide timing belt while distributing load forces evenly to avoid mechanical tooth wear. Featuring a raw stock pilot bore hub, it serves as an adaptable design choice for custom boring or specialized slotting in your machine shop.
