Product Description
DJM DBN51 Single Disc Locking Assembly Couplings
Â
The DJM DBN51 Series is a high-performance single-section diaphragm coupling that combines the advantages of flexible disc transmission with a keyless locking assembly . Designed for modern high-speed drive systems, it offers a simpler, more cost-effective alternative to traditional expansion sleeves while providing superior torque density and operational safety.
Â
Core Product Advantages
Integrated Locking Technology: Merges the misalignment compensation of a diaphragm coupling with the high-clamping force of a locking disc.
Superior to CSF-A1 Systems: Offers a simpler structure, lower cost, and easier installation/disassembly compared to CSF-A1 models, while supporting larger bore diameters.
High-Dynamic Stability: Specifically engineered for unstable motion scenarios, such as rapid acceleration, heavy braking, and continuous high-speed rotation.
Overload Protection: The keyless locking interface is designed to slip during extreme torque spikes, acting as a mechanical fuse to protect your motor and gearbox.
Premium 304 Stainless Steel Discs: High-elasticity laminated disc packs handle angular and axial misalignments with zero backlash.
Flexible Configuration: Compatible with both CSF-A7B and CSF-A10 type locking assemblies to suit specific engineering requirements.
Maintenance-Free & Durable: All-metal construction requires no lubrication and offers a long service life in harsh industrial environments.
