30-5M-25 HTD Pilot Bore Timing Pulley
The flanged 30-5M-25 HTD Timing Pulley brings absolute synchronous tracking and anti-slip operation to mechanical drivetrains. Guiding standard 25mm wide timing belts along an accurate 5mm curvilinear path, its 30 precision teeth handle rotational transfer cleanly with lower audible noise. The unfinished plain pilot bore layout lets builders customize the center hub exactly to unique millimetric constraints.
Product Features & Specifications
- Tooth Configuration: 30 synchronous precision-machined teeth.
- Pitch & Belt Width: 5mm curvilinear high-torque pitch designed for 25mm wide timing belts.
- Bore Adaptability: Stock plain pilot core to accommodate targeted custom reaming or set-screw drilling.
