ZG/LM Models

Our line-up includes the relatively low nominal torque of the ZG and LM models, which have excellent flexibility.The long type of the LM model (the LM-1 type) allows a particularly large angle of deflection of up to 14°. The ZG model uses a zinc alloy as the hub material and spring-steel square wire for the coil spring; the LM model uses an aluminum alloy as the hub material and stainless-steel round wire for the coil spring. Select the type suited to your usage environment.

Model Rated Torque [N・m] Misalignment Max. rotation speed [min-1 Torsional stiffness [N・m/rad] Moment of inertia [kg・m2 Mass [kg]
Parallel [mm] Angular [°] Axial [mm]
ZG-6 0.15 0.5 5 ±0.5 3000 0.17 1.95×10-7 0.020
