168-8M-30 HTD Pilot Bore Timing Pulley
The macro-diameter 168-8M-30 HTD Pilot Bore Timing Pulley delivers ultimate speed-reduction ratios and high structural torque tracking. Spreading rotational forces across 30mm wide belts via an accurate 8mm curvilinear track, it safeguards plant machinery from timing drops. Arriving as a pilot bore blank, it provides complete material flexibility for post-purchase reaming or specialized slotting.
