PB28-8M-20 Metric HTD Timing Pulley Pilot Bore
The PB28-8M-20 Metric HTD Timing Pulley provides high-torque, reliable synchronous power transmission for industrial machinery and drive assemblies requiring explicit anti-slip mechanics. Utilizing a curved HTD 8M pitch profile, it delivers consistent positioning capabilities and enhanced load distribution across medium and heavy-duty machinery networks. Prepped to manage 20mm wide synchronous timing belts, it comes standard as a plain minimum pilot bore item to allow precise localized machining matched precisely to your shaft specs.
Product Features & Specifications
- Tooth Configuration: 28 precision-milled HTD curvilinear teeth.
- Pitch & Belt Width: High-Torque Drive HTD 8mm Pitch (8mm tooth-to-tooth spacing) matched with 20mm wide synchronous bands.
- Shaft Mounting System: Stock Pilot Bore (Plain Minimum Bore) ready for personalized boring/keyway adjustments.
- Industrial Build Quality: Fabricated cleanly from robust Steel (St) stock to offer structural integrity and exceptional fatigue limits under active duties.
- Boring & Keying Readiness: Provided in standard raw stock configuration. Tailor the internal bore sizes directly to your shafts via our In-House Machining Services.
