10-3M-09 HTD Pilot Bore Timing Pulley [Aluminum Build]
The ultra-lightweight 10-3M-09 HTD Timing Pulley provides high mechanical flexibility for microscopic automation frameworks and precise electronic equipment. Utilizing a small 3mm curvilinear pitch explicitly paired with narrow 9mm wide timing belts, it maintains perfect positive drive tracking without adding radial mass latency to miniature stepper motors. Provided in a plain pilot bore format, it serves as an ideal blank for machine shop precision modifications.
Product Features & Specifications
- Tooth Configuration: 10 precision flanged teeth tracking a small 3mm HTD profile.
- Belt Compatibility: Tailored exclusively to manage low-mass 9mm wide synchronous timing belts.
- Bore Status: Stock plain Pilot Bore core layout to enable localized custom machine shop alterations.
- Premium Material Properties: Extruded out of specialized Aluminum UNI 9006 – T6 (Al) for low rotational inertia and great anti-corrosion life.
- Boring & Keying Readiness: Provided in standard raw stock configuration. Tailor the internal bore sizes directly to your shafts via our In-House Machining Services.
