144-14M-85 HTD Timing Pulley c/w TL 3525 Taper Lock Bush Bore
The large-diameter 144-14M-85 HTD Timing Pulley is built for massive mechanical reductions and substantial torque distribution in synchronous industrial drivetrains. Its large 144-tooth curvilinear path matches perfectly with 85mm wide timing belts to prevent jumping or mechanical slip under extreme system load variations. This model is pre-bored to accept a standard high-capacity TL 3525 Taper Lock bush system.
