144-14M-55 HTD Pilot Bore Timing Pulley
The large-diameter 144-14M-55 HTD Timing Pulley is built for massive reductions and substantial torque distribution in synchronous industrial drivetrains. Its large 144-tooth curvilinear path matches perfectly with 55mm wide timing belts to prevent jumping or mechanical slip under extreme system load variations. Arriving with an unmachined center hub pilot bore, it serves as an adaptable component for custom industrial machinery setups.
Product Features & Specifications
- Tooth Configuration: 144 heavy-duty industrial precision-machined teeth.
- Pitch & Belt Width: 14mm deep pitch optimized for high-load 55mm wide timing belts.
- Bore Status: Unmachined Pilot Bore center hub layout, letting you drill to unique millimetric constraints.
- Industrial Build Quality: Manufactured from premium high-strength Cast Iron (GG) or Steel (St).
- Boring & Keying Readiness: Provided in standard raw stock configuration. Tailor the internal bore sizes directly to your shafts via our In-House Machining Services.
