26-8M-85 HTD Pilot Bore Timing Pulley
The 26-8M-85 HTD Timing Pulley achieves premium torque distribution and anti-ratcheting safety thresholds across high-capacity drive systems. Guided along a deep 8mm curvilinear pitch, it pairs seamlessly with extra-wide 85mm timing belts to safely manage intense radial forces. The central plain pilot bore design allows engineers to drill, lathe-machine, or slot the core to meet specific application criteria.
