14-3M-09 HTD Pilot Bore Timing Pulley
The 14-3M-09 HTD Timing Pulley brings reliable zero-slip positive drive tracking to low-mass drivetrain designs. Its 14 precision curvilinear teeth follow an accurate 3mm pitch spacing, keeping 9mm wide timing belts firmly engaged without positive-drive friction spikes. Arriving as an unfinished stock hub with a small pilot hole, it simplifies true lathe centering for custom shaft boring, reaming, or set-screw clamping.
Product Features & Specifications
- Tooth Configuration: 14 heavy-duty synchronous precision teeth.
- Pitch & Belt Width: 3mm curvilinear high-torque pitch designed for 9mm wide timing belts.
- Bore Adaptability: Stock plain pilot core to allow personalized machine-shop reaming and keyway slotting.
- Premium Material Properties: Crafted from structural Aluminum UNI 9006 – T6 (Al) for weight optimization.
- Boring & Keying Readiness: Provided in standard raw stock configuration. Tailor the internal bore sizes directly to your shafts via our In-House Machining Services.
