Product Introduction
The Flexible Motor Shaft is a precision-engineered mechanical component designed to transmit rotary power from an electric motor to the driven equipment where alignment constraints, space limitations, or bending paths exist. By combining flexibility with stable torque transmission, it enables smooth and efficient power delivery in applications that require both adaptability and durability.
Manufactured from high-strength spring steel or alloy wire with advanced winding technology, our flexible motor shafts provide excellent torsional stability, wear resistance, and long service life. They are widely used in concrete vibrators, electric drills, polishing machines, grinding tools, cleaning equipment, and other motor-driven industrial or construction tools.
