144-14M-170 HTD Pilot Bore Timing Pulley

The large-diameter 144-14M-170 HTD Timing Pulley is built for massive mechanical reductions and substantial torque distribution in synchronous industrial drivetrains. Its large 144-tooth curvilinear path matches perfectly with ultra-wide 170mm 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 precision-machined heavy-duty teeth.
Pitch & Belt Width: 14mm deep pitch optimized for high-load 170mm 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.
