28-14M-85 HTD Pilot Bore Timing Pulley

The compact, extra-wide 28-14M-85 HTD Timing Pulley is custom-engineered to overcome intense start-stop forces inside compact machinery compartments. Featuring an aggressive 14mm curvilinear pitch structure to mesh with wide-format 85mm synchronous belts, it maintains perfect positive drive tracking. This structural solid block features a minimal pre-drilled pilot center hole to allow custom reaming and internal key slotting.

Pitch & Belt Width: Heavy 14mm pitch geometry optimized for wide 85mm synchronous drive belts.
Bore Adaptability: Stock plain Pilot Bore core to accommodate comprehensive personalized engineering shop alterations.
