28-3M-15 HTD Pilot Bore Timing Pulley [Aluminum Build]
The lightweight 28-3M-15 HTD Timing Pulley provides high mechanical flexibility for compact automation frameworks requiring quick response times. Utilizing a small 3mm curvilinear pitch explicitly paired with narrow 15mm wide timing belts, it maintains perfect positive drive tracking without adding radial mass to small-scale motors. Provided in blank stock pilot bore configuration, it leaves the central hub open for customized boring or set-screw positioning.
Product Features & Specifications
- Tooth Configuration: 28 precision flanged teeth tracking a small 3mm HTD profile.
- Belt Compatibility: Tailored exclusively to manage low-mass 15mm wide synchronous timing belts.
- Bore Status: Unmachined blank 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.
