48-8M-30 HTD Pilot Bore Timing Pulley
The large-format 48-8M-30 HTD Pilot Bore Timing Pulley delivers high mechanical reduction ratios and stable synchronous power tracking. Designed to drive 30mm wide timing belts across its 48 deep curvilinear teeth, it minimizes friction and optimizes load transfer across complex layouts. The central hub arrives as a plain pilot bore to accommodate custom machining to non-standard shaft tolerances.
Product Features & Specifications
- Tooth Configuration: 48 heavy-duty synchronous HTD teeth.
- Pitch & Belt Width: 8mm heavy industrial pitch designed for 30mm wide timing belts.
- Bore Status: Unfinished Pilot Bore center layout to facilitate specialized post-purchase reaming.
