Description
TSUBAKI GMTK — TERVO Speed Reducer for Servo Motors (Helical Gear), genuine TSUBAKI product.
Overview
The TERVO is a TSUBAKI helical gear speed reducer designed specifically for servo motors. It mounts directly to the servo flange and reduces speed while multiplying torque, with low backlash for accurate positioning. It is used in automation, robotics, indexing tables and packaging machines driven by AC servo motors.
Key Features
- Designed for direct servo motor mounting
- Helical gearing for smooth, quiet running
- Low backlash for positioning accuracy
- Range of reduction ratios
