    SHF-2UH

    SHF - 2UH harmonic drive gearheads have been developed focusing on ease of use and total cost reduction. With a hollow-shaft construction adopted as standard, these gearheads are credited with a high level of space economy, because the hollow-shaft construction provides room for other drive shafts and can also be used for wiring. Gearheads of this type can also provide direct support for external loads due to their built-in high rigidity cross roller bearings.

    SHF-2UJ

    These harmonic drive gearheads have been developed focusing on the importance of ease of use and total cost reduction. In order to facilitate connectivity with motors, SHF - 2UJ harmonic drive gearheads are offered with input axes included as standard. SHF - 2UJ series products are finding their way into a wider variety of applications.
