GRC Aluminum alloy bellows clamping coupling
Product Detail

Features:

1. Bellows shaft coupling has no clearance and high sensitivity

2. High elasticity, better protection of equipment

3. Can absorb vibration, while compensating radial, angular and axial deviation ability

4. oil resistance, corrosion resistance

5. Torsional rigidity, clockwise and counterclockwise rotation characteristics are exactly the same

6. Often used in CNC machine tools, indexing plate and other industrial machinery
