122-14M-55 HTD Pilot Bore Timing Pulley
The large-scale 122-14M-55 HTD Timing Pulley is custom-engineered for heavy industrial speed-reduction setups requiring extensive torque handling capacity. Its wide 122-tooth curvilinear layout provides excellent contact tracking when driving a 55mm wide timing belt, eliminating mechanical slip. The structural center hub arrives as a plain pilot bore to accommodate custom machining to non-standard shaft tolerances.
