Sumitomo Fine Cyclo UA-Series Motion Control

Overview

Spur gear pre-stage and three or four (UA115) eccentrics providing high transmission accuracy, minimum speed ripples and minimum vibration.

The new UA series offers improved performance in torque density, positioning accuracy, and movement accuracy. Additionally, the Fine Cycle UA series has improved output bearings, and is highly efficient even at low speeds.

Less than 0.5 arcmin Lost Motion Ideal for applications with traverse movements Highest Torque density available on the market Highest overall available Torque High input and output speeds possible Additional ratios available on request

Variants:

Basic design to be fully integrated in robotic arms Fully sealed version including motor flange available
