• Build to Last: Our product uses high-quality cast aluminum and hollow steel tube material and is characterized by heat resistance, wear resistance, high quality, and long service life through die-casting and heat treatment.
• Powerful Motor: It adopts a single-phase pure copper motor with low loss, low noise, fast heat dissipation, and high return accuracy, which can greatly improve work efficiency.
• Stable Operation: Both ends of the rotor are equipped with ball bearings, which can reduce friction and temperature during use to ensure stable operation.
• High Safety: The slow start function can effectively avoid current overshoot and protect the motor.
• Self-locking Function: With a self-locking function (clockwise/counterclockwise self-locking), the output shaft should not move even when the motor is power-off.
