28-14M-170 HTD Pilot Bore Timing Pulley

The compact, ultra-wide 28-14M-170 HTD Timing Pulley is engineered to handle massive mechanical loads in space-restricted machinery hubs. Combining a heavy-duty 14mm curvilinear tooth architecture with an extreme 170mm face width configuration, it acts as a robust positive drive anchor that eliminates tooth shear or belt ratcheting under high shock dynamics. It is supplied as a plain pilot bore core to enable localized custom machine shop alterations.

Product Features & Specifications

Tooth Configuration: 28 high-capacity precision-machined industrial teeth.
Pitch & Belt Width: 14mm large pitch profile designed explicitly for ultra-wide 170mm timing belts.
Bore Adaptability: Stock plain Pilot Bore core to allow personalized machine-shop alterations.
Industrial Build Quality: Formed using premium-grade solid Steel (St) to maintain structural integrity.
Boring & Keying Readiness: Provided in standard raw stock configuration. Tailor the internal bore sizes directly to your shafts via our In-House Machining Services.
