Synchronous Pulley — HTD 5M, 12 Teeth, 5mm Pitch Key benefits Accurate, repeatable motion: Designed to work with HTD 5M timing belts for reliable, low-backlash power transmission in precise positioning applications. Easy compatibility: Multiple bore and width options let you match the pulley directly to common motor and shaft sizes without custom machining. Stable performance: 12-tooth design and 5mm pitch provide consistent engagement with 5M belts to reduce slippage and vibration in small to medium drive systems. What it does and why you need it Transfers torque and timing between shafts with precision, keeping belt-driven systems synchronized. Solves common problems like belt skipping, uneven motion, and misalignment by pairing a correctly sized pulley with an HTD 5M belt. Useful whenever you need dependable mechanical timing in compact systems—especially where space is limited and accurate tooth engagement is critical. Specifications (consistent with original listing) Model: HTD 5M type (Synchronous Pulley) Pitch: 5 mm (5M) Number of teeth: 12 Bore options: 5 mm, 6 mm, 6.35 mm, 8 mm, 10 mm (select the bore that matches your shaft) Width options: 16 mm or 21 mm Compatibility and performance Fits standard HTD 5M timing belts and mating pulleys. Available bore sizes cover typical motor and shaft standards for easy retrofit and replacement. Two width options accommodate different belt widths or load requirements without changing pulley pitch or tooth count. Typical applications (practical use cases) 3D printers and CNC routers: precise motion control for X/Y/Z axes and extruder feeds where small, accurate pulleys are required. Small robotics and automation: timing drives for robot arms, gantries, and pick-and-place mechanisms needing synchronized motion. Light-duty conveyors and feeders: compact drives that require repeatable indexing and minimal backlash. Installation tips Choose the bore that matches your shaft diameter for a secure fit; use proper mounting hardware or a matching hub as required by your equipment. Verify belt width and pulley width compatibility (16 mm or 21 mm) before installation to ensure full tooth engagement. What’s included One HTD 5M synchronous pulley, 12 teeth, 5 mm pitch, with your choice of bore and width per the options listed. Reliable, straightforward replacement or upgrade for HTD 5M belt drives — select the bore and width you need for direct fit and consistent timing performance.
