Advanced Power Transmission: DJM & SJM Locking Assembly Diaphragm Couplings

The DJM (Single) and SJM (Double) series represent a breakthrough in coupling technology by integrating the high-torque capacity of a diaphragm coupling with the precision of a locking assembly . This keyless connection simplifies production, reduces costs, and provides a highly reliable link for modern transmission systems that demand rapid acceleration and frequent braking.

Core Product Advantages

• Integrated Locking Assembly Features: Combines the misalignment compensation of diaphragm couplings with the superior gripping power of expansion sleeves.

• Simplified & Cost-Effective: More efficient and easier to install than standard CSF-A1 type assemblies, allowing for larger bore sizes and simplified shaft designs.

• Optimized for Dynamic Loads: Specifically engineered for unstable motion scenarios, including rapid acceleration, heavy braking, and continuous high-speed rotation.

• Overload Protection: Designed to be reusable; the unit acts as a safety mechanism by slipping during extreme overload conditions to protect expensive mechanical components.

• Flexible Locking Options: Compatible with both CSF-A7B and CSF-A10 type locking assemblies to meet varying tightening requirements.

• Zero Backlash Maintenance-Free: The all-metal construction ensures a rigid, zero-backlash connection that requires no lubrication and minimal maintenance.
