Industrial Robot High Precision Diaphragm Coupling Stainless Steel Bellows Drive Coupling Element
Industrial robot diaphragm/bellows couplings are core connecting elements in precision transmission systems, specifically designed for high-end industrial automation applications. This product uses high-strength stainless steel material manufactured through special forming processes, enabling torque transmission while compensating for axial, angular, and radial misalignments.
Key Features
High Torsional Rigidity: Multi-layer stainless steel diaphragm structure with up to 98% torque transmission efficiency, ensuring zero-backlash transmission
Zero Backlash Drive: Specially designed bellows structure effectively eliminates transmission clearance, achieving repeat positioning accuracy of ±0.01mm
Strong Misalignment Compensation: Simultaneously compensates for axial, angular, and radial deviations, allowing 0.03mm eccentricity error
Maintenance-Free Design: No lubrication needed, integrated sealing structure provides IP65 protection rating, suitable for harsh industrial environments
Extended Service Life: Premium stainless steel material withstands over 100,000 fatigue tests with wear less than 0.01mm
