Product introduction
The elastic element of bellows coupling is precision metal bellows, which is divided into flexible series and rigid series. The flexible series has great elasticity and is often used in micro occasions such as encoders and sensors. The rigid series is mainly used in servo motors, CNC machine tools (machining centers) and other occasions.
Products Features
1. The bellows coupling has no clearance and high sensitivity
2. High elasticity, better protection of equipment
3. It can absorb vibration and compensate radial, angular and axial deviations at the same time
4. Oil stain resistance and strong corrosion resistance
5. Torsional rigidity, clockwise and counterclockwise rotation characteristics are exactly the same
6. Commonly used in CNC machine tools, indexing discs and other industrial machinery
