64-8M-85 HTD Timing Pulley [Pilot Bore Variant]
The 64-8M-85 HTD Timing Pulley ensures continuous mechanical efficiency inside automation power systems. Spreading radial tension smoothly across wide 85mm timing belts, its 64 deep curvilinear teeth minimize premature drive failure. Provided with a plain stock pilot bore, it is ideal for custom boring and precision keyway cutting.
Product Features & Specifications
- Tooth Configuration: 64 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: Fabricated using robust Cast Iron (GG) or Steel (St).
