The 86J18118-460 is an 8.5 N·m NEMA34 Stepper Motor, a 2-phase 86 mm-frame motor, 118 mm long, delivering 8.5 N·m at 6.0 A through a 12.7 mm shaft. It is a mid-range torque option well matched to the standard NEMA34 drive ecosystem.
At 8.5 N·m the motor covers conveyor indexing, labeler drives and gantry positioning within compact industrial automation. The 12.7 mm shaft accepts standard NEMA34 pulleys and couplings, simplifying mechanical design.
Packaging machines use such an axis for feeding, sealing and diverting stations; textile machines position rollers and print heads. Consistent torque and smooth stepping limit frame vibration and registration error across a run. Food-processing conveyors also benefit from the steady low-speed output and simple open-loop wiring.
A tightly controlled rotor-stator air gap lowers heating and noise, improving duty-cycle reliability in continuous operation. The reduced noise level is a practical advantage in production halls where multiple axes run side by side.
At 8.5 N·m this motor sits between the compact 80 mm body and the long 156 mm unit. It is the right pick when a machine needs more torque than the short frame provides but does not require the full-length body and its extra rotor inertia. Standardizing the NEMA34 mounting pattern across these options lets designers swap body lengths with minimal mechanical rework.
Pair the 6.0 A winding with a driver rated for continuous rated current. Standardization on 12.7 mm shaft hardware reduces coupling inventory across the machine. Confirm the torque-speed curve covers the required operating RPM and allow airflow for sustained cycling. Lyenwsin can supply the drive and motor as a matched set with application support.
