Premium Jaw Coupling Solutions for Reliable and Flexible Power Transmission

In the realm of industrial power transmission, a robust and versatile jaw coupling is fundamental for connecting drive shafts efficiently while accommodating real-world imperfections. At Apexcoupling, we specialize in manufacturing the high-quality DJ-A series jaw coupling, a quintessential flexible coupling designed for durability, smooth operation, and minimal maintenance. The core of this jaw coupling features two metallic jaw hubs machined from 45# steel, which interlock with a central polyurethane (PU) elastomeric spider. This simple yet highly effective jaw coupling design is engineered to transmit torque reliably while damping vibrations, absorbing shock loads, and compensating for parallel, angular, and axial shaft misalignments. As a direct factory with extensive export experience, we provide standard jaw coupling units and fully support OEM, ODM, and OBM customization to ensure the perfect fit for your specific application, making us your ideal partner for all jaw coupling needs.

The effectiveness of our jaw coupling stems from the synergistic relationship between its hardened steel hubs and the resilient PU spider. The hubs of this jaw coupling are precision-machined to ensure perfect concentricity and feature a standard blackening surface treatment for enhanced corrosion resistance. The heart of the jaw coupling, the elastomeric spider, is available in various hardness grades to tailor performance, balancing flexibility with torque capacity. This versatile jaw coupling is capable of handling a wide nominal torque range from 125 N.m to 16,000 N.m, with speeds adaptable from 1000 to 3800 RPM, exemplified by our standard 20mm bore model rated for 100 N.m at 2000 RPM. Whether you require a standard jaw coupling or a custom solution with specific bore sizes, materials like stainless steel for corrosive environments, or specialized elastomers for extreme temperatures, our engineering team can configure the ideal jaw coupling for your machinery. The jaw coupling‘s maintenance-free design, requiring no lubrication, makes it a cost-effective and reliable choice for countless industrial settings.

Advantages of Choosing Our Jaw Coupling

Selecting our professional-grade jaw coupling delivers significant operational benefits to your system:

• Superior Vibration Damping: The elastic spider in the jaw coupling effectively isolates and dampens torsional vibrations, protecting sensitive components.

• Effective Misalignment Compensation: This jaw coupling accommodates unavoidable shaft misalignments, reducing bearing loads and prolonging equipment life.

• Shock Load Absorption: The jaw coupling cushions the drivetrain against sudden torque spikes and start/stop impacts.

• Maintenance-Free Operation: Unlike geared couplings, this jaw coupling requires no lubrication, saving time and operational costs.

• Easy Installation & Replacement: The simple two-hub and spider design of the jaw coupling allows for quick assembly and easy spider replacement during service.
