Welcome to Hebei Speed Torque Transmission Technology Co., Ltd. As a professional manufacturer established in 2017, we specialize in high-performance power transmission components. Our High Torque Double Diaphragm Shaft Coupling Clamp Disc Coupler is engineered to deliver exceptional torque transmission and misalignment compensation for industrial motor applications. With a factory spanning 3,000-5,000 square meters and a dedicated team of 101-200 employees, we ensure every coupler meets rigorous quality standards.
This clamp disc coupler features a unique double diaphragm design that provides high torsional stiffness while accommodating angular, parallel, and axial misalignments. It is ideal for demanding industrial environments where precision and reliability are critical. Whether you are connecting motors to pumps, compressors, or gearboxes, this coupling offers a maintenance-free solution with long service life.
Key Features & Advantages
High Torque Capacity: Designed to handle up to 5000 Nm depending on size, suitable for medium to heavy-duty industrial motors.
Double Diaphragm Design: Provides excellent misalignment compensation (angular up to 1°, parallel up to 0.5mm, axial up to ±0.3mm) without generating reaction forces on bearings.
Clamp Disc Hub: Easy installation and removal with clamping screws; no keyway required, reducing backlash and wear.
Zero Backlash: Ensures precise motion control and reduces vibration, enhancing equipment accuracy.
Maintenance-Free: No lubrication needed; all-metal design resists harsh environments, high temperatures, and corrosive media.
Balanced Design: Precision balanced for high-speed operation up to 6000 RPM, minimizing vibration.
Customizable Options: Bore diameters, materials (alloy steel, stainless steel), and special coatings available upon request.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a double diaphragm coupler and a single diaphragm coupler?
A: Double diaphragm couplers offer higher torque capacity and better misalignment compensation compared to single diaphragm designs. They are also more resistant to torsional fatigue, making them ideal for heavy-duty applications.
Q2: Can this coupling be used with high-speed motors?
A: Yes, our clamp disc coupler is dynamically balanced and can operate at speeds up to 6000 RPM. For higher speeds, please consult our engineering team for custom balancing options.
Q3: Does the coupling require any maintenance?
A: No, the all-metal construction and diaphragm design eliminate the need for lubrication. Periodic visual inspection is recommended, but no routine maintenance is required.
Q4: What bore sizes are available?
A: Standard bore diameters range from 10mm to 100mm. Custom bores can be machined per your specifications. Please provide shaft dimensions when ordering.
Q5: Is the coupling suitable for corrosive environments?
A: Yes, we offer stainless steel versions and optional anti-corrosion coatings for harsh environments such as chemical plants, marine applications, or food processing.
Q6: How do I install the clamp disc coupler?
A: Simply slide the coupler onto the shafts, align the hubs, and tighten the clamping screws evenly using a torque wrench. No keyways or set screws are needed, simplifying installation.
Q7: What is the typical lead time?
A: For standard sizes, lead time is 7-15 days. Custom orders may require 15-25 days depending on complexity. We also offer expedited shipping for urgent requirements.
Q8: Do you provide samples for testing?
A: Yes, we can provide sample units. Please contact our sales team to discuss sample policies and costs. We are confident that our coupling will meet your expectations.
