Product Introduction
The Concrete Vibrator Flexible Shaft is a precision-engineered power transmission component specifically designed for internal concrete vibrators. It efficiently transfers rotary motion from the drive motor to the vibrator poker while maintaining flexibility, stability, and durability during operation.
Manufactured from high-strength spring steel wire and wear-resistant outer protection, this flexible shaft is built to withstand continuous bending, high torque loads, and harsh construction environments. It is an essential component for ensuring stable vibration performance, reliable concrete compaction, and long service life in both light-duty and heavy-duty concrete works.
