30-3M-09 HTD Pilot Bore Timing Pulley
The flanged 30-3M-09 HTD Timing Pulley brings absolute synchronous tracking and anti-slip operation to low-mass drivetrain sub-sections. Guiding 9mm wide timing belts along an accurate 3mm curvilinear path, its 30 precision teeth handle rotational transfer cleanly with minimal noise levels. The unfinished plain pilot bore layout lets builders customize the center hub exactly to unique millimetric constraints.
