20-3M-15 HTD Pilot Bore Timing Pulley
The flanged 20-3M-15 HTD Timing Pulley is engineered to deliver precise, high-ratio reductions in synchronous drive frameworks. Spreading structural torque dynamics smoothly across 15mm wide timing belts, its 20 deep curvilinear teeth prevent mechanical timing fatigue. Arriving as an unmachined pilot bore blank, it provides complete machine shop freedom to create custom keyways or set-screw fittings.
Product Features & Specifications
- Tooth Configuration: 20 precision-machined heavy-duty HTD teeth.
- Pitch & Belt Width: 3mm heavy pitch profile designed specifically for standard 15mm wide timing belts.
