80-8M-20 HTD Pilot Bore Timing Pulley
The heavy-duty 80-8M-20 HTD Pilot Bore Timing Pulley is engineered to handle massive reductions and substantial torque distribution in synchronous industrial drivetrains. Its large 80-tooth curvilinear path matches perfectly with 20mm wide timing belts to prevent jumping or mechanical slip under extreme system load variations. Arriving as a pilot bore blank, the central hub gives engineers material leeway to ream out custom diameters.
Product Features & Specifications
- Tooth Configuration: 80 precision-machined heavy-duty teeth.
- Pitch & Belt Width: 8mm large pitch profile designed for 20mm wide timing belts.
