1.3M HTD Timing Pulley — 17 Teeth, Aluminum Alloy Key benefits Precise, reliable power transmission: The 1.3M HTD tooth profile provides positive tooth engagement for accurate positioning and repeatable motion. Compact design for tight installations: The 17-tooth pulley delivers a small-diameter solution where space is limited or short center distances are required. Lightweight and corrosion-resistant: Manufactured from aluminum alloy for good strength-to-weight ratio and long service life in light to moderate duty applications. Flexible mounting options: Available with three bore sizes (7 mm, 8 mm, or 10 mm) to match common shaft diameters without modification. What it is and how it solves problems This is a 1.3M pitch HTD timing pulley with 17 teeth, built to work with matching 1.3M HTD belts. It eliminates belt slip and improves timing accuracy compared with friction drives, making it suitable for precise motion systems. Multiple bore sizes and support for three standard belt widths let you select the right combination for your shaft and load requirements, reducing the need for adapters or complex machining. Key specifications Tooth profile: HTD (1.3M pitch) Teeth: 17 Bore options: 7 mm, 8 mm, 10 mm Compatible belt widths: 6 mm, 10 mm, 15 mm Material: Aluminum alloy Typical applications 3D printers and CNC axes: Compact timing pulley for belt-driven X/Y/Z stages where accuracy and low inertia matter. Desktop and educational robotics: Precise motion and easy shaft fitting for small robot arms, gantries, and positioning systems. Light automation and packaging equipment: Reliable drive for conveyors, feeders, and other small material-handling mechanisms. Installation notes Choose the bore that matches your shaft (7, 8, or 10 mm) and use the corresponding 1.3M HTD belt width (6/10/15 mm) for optimal engagement. For interference or set-screw mounting, verify shaft preparation and any required fasteners—this pulley is supplied as the machined aluminum component. This 1.3M HTD 17-tooth aluminum pulley offers a compact, durable option for precise belt-driven systems requiring multiple bore and belt-width choices.
