GT2 16T Timing Pulley — 6 mm Belt, 3 mm Bore, 7 mm Width Key features and specifications Designed for GT2 timing belts with 6 mm belt width. Number of teeth: 16T — suitable for small pulley ratios and precise linear motion. Bore diameter: 3 mm — fits 3 mm diameter shafts. Pulley width: 7 mm — accommodates the 6 mm belt with slight clearance. Why you need this pulley Accurate motion control: The 16tooth GT2 profile provides consistent tooth engagement for precise positioning and smooth belt travel. Simple compatibility: Sized specifically for 6 mm GT2 belts and 3 mm shafts, reducing the need for adapters or modifications. Compact and spaceefficient: Small diameter and narrow width are ideal when design space is limited or when light, compact drive components are required. How it solves common problems Prevents belt slip and reduces backlash by matching the GT2 tooth profile to the belt, improving repeatability in motion systems. Eliminates fitment guesswork with a defined 3 mm bore and 7 mm overall width, making installation straightforward. Helps maintain belt alignment and tension in compact assemblies where larger pulleys would not fit. Applications and use scenarios 3D printers: Drive X/Y axes or small Zaxis stages where precise, lowbacklash motion is required and space is limited. Small CNC or laser machines: Use in compact drive trains for accurate positioning of workheads or material feeds. Hobby robotics and automation: Ideal for lightweight robot arms, linear slides, or beltdriven actuators that use GT2 belts and 3 mm shafts. Notes for selection and installation Confirm shaft diameter is 3 mm for direct fit; if using a different shaft size, an appropriate adapter or bushing is required. Pair with a GT2 6 mm wide timing belt to ensure correct tooth engagement and performance. This pulley is a straightforward replacement or upgrade part where a 16tooth GT2 pulley with a 3 mm bore and 7 mm width is required.
