Industrial Applications

• Robot wrist and base axis reduction.
• High-torque transmission for positioning.
• Payload handling joints.

Design Purpose

Reduce motor speed and multiply torque to deliver precise, high-rigidity axis motion. A damaged R/B/T-Axis Speed Reducer shows up as bearing and gear-tooth wear from overload. Replacing it with the same part number restores normal operation. The work is done at the robot, so the unit must be made safe before the part is changed.

Common Failure Modes

• Bearing and gear-tooth wear from overload.
• Lubrication breakdown.
• Backlash increase affecting repeatability.

Specific alarm codes are not officially documented for this model. Please contact us with the fault code shown on your controller for accurate diagnosis.
