Synchronous Pulley — HTD 5M, 12 Teeth Why choose this pulley Precise, reliable power transmission for synchronous drive systems using HTD 5M belts. Multiple bore options and two widths give you a close fit to existing shafts and belt widths, reducing downtime and simplifying replacement. Compact 12-tooth design is effective where short center distances and compact assemblies are required. Key specifications Product name: Synchronous Pulley (Timing Belt Pulley) Model: 5M type (HTD 5M profile) Pitch: 5 mm (HTD 5M) Number of teeth: 12 Bore (shaft) options: 5 mm, 6 mm, 6.35 mm (1/4"), 8 mm, 10 mm Width options: 16 mm or 21 mm Functional benefits Accurate tooth engagement minimizes slippage and improves positioning repeatability in indexing and motion control applications. Available bore sizes accommodate common shaft diameters for straightforward installation without custom machining. Two width options allow compatibility with standard 5M belt widths and help match belt load capacity to your application. Typical applications 3D printers and desktop CNC machines: compact, accurate motion transfer in small-frame equipment. Robotics and automation: dependable synchronization for small actuators and gantry drives. Light-duty conveyors and packaging equipment: compact pulleys for short center distances or space-constrained layouts. Installation notes Select the bore that matches your shaft; common press-fit or set‑screw mounting methods apply depending on your hub and shaft arrangement. Choose 16 mm or 21 mm width to match belt width and expected load; wider pulleys provide greater belt contact area for higher loads. This HTD 5M 12T pulley delivers a straightforward, compatible solution for compact synchronous drive requirements.
