Steel Bellows Clamping Shaft Coupling Stepped For Encoder
Product introduction
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
