Harmonic Drive FBS-2UH Hollow-Shaft Gear Units
Harmonic Drive FBS-2UH is a flat hollow-shaft gear-unit family with an integrated output bearing. Its central opening allows a machine designer to route services through a rotary axis, while sizes 25 and 32 and ratios of 30:1, 50:1 and 100:1 provide distinct torque and stiffness choices.

Review Summary
FBS-2UH is worth considering where through-axis routing and axial packaging are important. Select the complete size-and-ratio combination against the load cycle, external bearing loads and required stiffness. A large bore and a high peak-torque figure do not establish the continuous operating capacity of the finished axis.
