Key features and benefits Belt width compatibility: designed for a 15 mm belt width, ensuring proper seating and drive engagement. Shape: BF type pulley for accurate alignment with BF profile belts. Material: aluminum alloy provides a balance of strength and lightweight performance for reliable operation and reduced inertia. Teeth options: available with 72 teeth or 75 teeth to suit different gear ratios and drive requirements. Why this pulley matters Reliable compatibility with 15 mm belt systems and BF type belts, helping achieve smooth, consistent motion. Durable yet lightweight aluminum alloy construction supports fast response and longer service life in moving assemblies. Choice of 72 or 75 teeth gives flexibility to tailor speed and torque to your application without changing other components. Use scenarios 3D printers and other smallscale fabrication equipment that use BF type belt drives with a 15 mm belt width. Custom automation projects, robotics, or hobby CNC setups requiring a BF type pulley with either 72 or 75 teeth for the desired speed/torque. Replacement pulley in existing BFtype belt drive systems, such as lightduty conveyors or compact CNC/routing machines, where 15 mm belts are used.
