44-8M-85 HTD Timing Pulley [Pilot Bore Variant]
The mid-sized 44-8M-85 HTD Timing Pulley offers robust structural body strength and plain bore multi-adaptability. Spreading mechanical torque cleanly across 85mm wide synchronous timing belts via an 8mm curvilinear path, it facilitates maximum drive efficiency. Arriving as a pilot bore blank, it can be seamlessly customized to non-standard shaft tolerances.
Product Features & Specifications
- Tooth Configuration: 44 precision-machined synchronous HTD teeth.
- Pitch & Belt Width: 8mm high-torque drive profile engineered for 85mm wide timing belts.
- Bore Status: Unbored stock hub with a small pilot hole to facilitate clean lathe centering.
- Industrial Build Quality: Constructed from rigid Cast Iron (GG) or solid heavy 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.
