Harmonic Drive LLC announces new gear unit with large Hollow Bore

POSTED 09/20/2019

 Harmonic Drive LLC, the leader in high precision motion control announces new gear units with extra-large through hole and compact outer dimensions. The new series, FBS-2UH is a flat, pancake style gear unit.

This new Harmonic Drive® gear 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 design features Harmonic Drive's “S” tooth profile for optimal tooth engagement resulting in high torque, high-torsional stiffness, long life and smooth rotation.  Precision cross roller bearing incorporated into the design supports the external load. FBS Series is available in two sizes (25, 32) and two ratios (30:1, 50:1).

  • 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
  • Peak torque 25-92 Nm

Harmonic Drive will show the gear unit at Robobusiness 2019 in Santa Clara this October, booth 205.
