Product: 5M20T timing pulley Key benefits Precise synchronous power transmission: Designed for use with 5M pitch timing belts to ensure accurate, slip motion between shafts and driven elements. Flexible fit for many shafts: Multiple inner bore options let you match the pulley to common shaft diameters without custom machining. Lightweight and corrosionresistant: Aluminum alloy construction reduces rotating mass while resisting corrosion for longer service life. Supports different belt widths: Available for 15 mm, 20 mm, and 25 mm belt widths, making it easy to match belt crosssection and load capacity. Important specifications Model: 5M20T (5M pitch, 20 teeth) Inner bore options (mm): 5 / 6 / 6.35 / 7 / 8 / 10 / 11 / 12 / 12.7 / 14 / 15 / 16 / 17 / 19 / 20 For belt widths: 15 mm, 20 mm, 25 mm Material: Aluminum alloy Why customers choose this pulley Compatibility: Directly compatible with 5M timing belts and commonly used shaft diameters listed above, simplifying parts selection and replacement. Versatility: Multiple bore sizes and beltwidth options cover a wide range of small to mediumduty mechanical systems. Performanceoriented material: Aluminum alloy balances strength and low inertia, improving responsiveness in dynamic systems. Typical use scenarios Compact robotics and automation: Use as a drive pulley in robot arms, gantries, or pickandplace systems where precise position control and reduced inertia matter. CNC and motioncontrol equipment: Install on stepper or servo shafts for synchronized axis movement in small CNC routers, laser cutters, or XY tables. Conveyor and feeder mechanisms: Implement in light to mediumduty conveyor drives or partfeeding systems that require timing accuracy and minimal belt slip. Installation notes Select the inner bore matching the shaft diameter to avoid additional machining. Choose the belt width that corresponds to the load and belt specification (15 mm / 20 mm / 25 mm). Ensure compatibility with 5M pitch timing belts and verify tooth count (20T) meets required gear ratio. Materials and durability Constructed from aluminum alloy for reduced weight and improved corrosion resistance compared with typical steel pulleys. Suitable for repetitive, precision motion where low inertia and reliable tooth engagement are required. Available configurations 5M20T pulleys with the listed inner bore sizes and for belt widths of 15 mm, 20 mm, or 25 mm. Select the exact bore and beltwidth combination required for your shaft and belt.
