112-8M-30 HTD Pilot Bore Timing Pulley
The massive 112-8M-30 HTD Pilot Bore Timing Pulley stands as an extensive ratio reduction framework for 30mm wide heavy synchronous configurations. Spreading high rotational tension evenly across its 112 teeth, it completely eliminates tooth deformation and tracking errors. The central hub arrives as a plain pilot bore to accommodate custom machining to non-standard shaft tolerances.
Product Features & Specifications
- Tooth Configuration: 112 precision-machined heavy-duty teeth.
- Pitch & Belt Width: 8mm heavy pitch profile designed for 30mm wide timing belts.
- Bore Status: Unfinished Pilot Bore center layout to facilitate specialized post-purchase reaming.
- Industrial Materials: Fabricated using premium-grade, structural 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.
