The new FBS-2UH gear unit series from Harmonic Drive features a large, hollow shaft with a compact outer diameter. The extra large hollow shaft is ideal for robots and machines requiring complex cabling to pass through the axis of rotation.
The new gear unit design features Harmonic Drive's “S” tooth profile for optimal tooth engagement resulting in high torque, high-torsional stiffness, long life and smooth rotation.
The FBS-2UH Series is available in two sizes (25, 32) and three ratios (30:1, 50:1, and 100:1).
Key features include:
- - Extra large hollow-shaft diameter is our largest yet for a standard product
- - Compact dimensions for use in robotics
- - Outer diameter and hollow bore optimized for design flexibility and performance
- - Zero Backlash
- - Accuracy <1 arc-min
- - High torsional stiffness
- - High efficiency
- - Smooth operation
- - Robust cross roller output bearing

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
