Design and Features
The F4CF–UA 25 is a compact, precise, and moment-stiff gearbox suitable for high dynamics and positioning accuracy. It is part of the UA series, which includes six different sizes. The UA 25 model features:
  • Outer diameter of 159 mm
  • Two-stage reduction gear with cycloid discs and spur gears
  • Low vibration levels and optimally distributed load forces
  • Rated torque up to 695 Nm and acceleration torque up to 1,250 Nm
  • Emergency stop capability up to 2,500 Nm
  • Angular ball bearings for tilt moments up to 1,666 Nm
Applications and Mounting
The gearbox is designed for use in robotics and machine tools, offering high positioning and path accuracy under dynamic loads. It can be mounted in various configurations, including:
  • Output flange rotates (standard design)
  • Gearbox housing rotates (optionally in keyway design)
These configurations allow for integration with robot arms, machine parts, and customer-specific applications.
