Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017 with a factory spanning 3,000–5,000 square meters and supported by over 100 skilled employees, presents our Customizable Metal Diaphragm Coupling Disc engineered for low noise and non‑lubrication operation. This coupling disc is designed to deliver precise torque transmission while eliminating the need for regular maintenance, making it an ideal solution for industries requiring high reliability and quiet performance. With our ISO9001-certified manufacturing processes, we ensure consistent quality and dimensional accuracy in every disc we produce.
Our metal diaphragm coupling disc utilizes a flexible metal diaphragm that compensates for misalignment while dampening vibration and noise. Unlike traditional elastomeric couplings, this all-metal design requires no lubrication, reducing maintenance costs and environmental concerns. The disc is available in multiple configurations—single disc for compact applications or double disc for higher misalignment capacity—and can be customized to meet specific bore sizes, outer diameters, and thicknesses.
Key Features & Technical Specifications
- Low Noise Operation: The metal diaphragm design minimizes noise generation, typically below 60 dB, making it suitable for noise-sensitive environments like medical equipment or precision laboratories.
- Non-Lubrication: No grease, oil, or seals required—eliminates leakage risks and reduces maintenance downtime.
- High Misalignment Capacity: Accommodates angular, parallel, and axial misalignments without sacrificing performance.
- Customizable Dimensions: Bore sizes from 10 mm to 200 mm, outer diameters from 50 mm to 400 mm, and thicknesses tailored to your torque requirements.
- Wide Torque Range: Standard torque ratings from 10 N·m up to 5000 N·m, with higher capacities available upon request.
- Temperature Resistance: Operates reliably in temperatures from -40°C to +200°C due to all-metal construction.
- Backlash-Free: Zero backlash design ensures precise motion control for servo drives and positioning systems.

The disc’s design also features a unique flexible element that reduces peak loads during start-up and shock absorption, protecting connected equipment. The non-lubrication feature is particularly advantageous in food processing, cleanroom, or pharmaceutical applications where contamination must be avoided. Additionally, the coupling disc is lightweight yet robust, contributing to overall system efficiency.
Benefits for Your Application

Frequently Asked Questions (FAQ)
-
Q1: What is the maximum torque capacity of the customizable metal diaphragm coupling disc?
A: The standard torque capacity ranges from 10 N·m to 5000 N·m. Higher torque ratings are available as a custom option. Please contact our sales team with your specific requirements. -
Q2: Can the coupling disc be used in high-temperature environments?
A: Yes, the all-metal construction allows operation in temperatures from -40°C to +200°C. For extreme temperatures above 200°C, special materials can be selected upon request. -
Q3: Do I need to apply any lubricant to the diaphragm?
A: No. The metal diaphragm coupling disc is designed for non-lubrication operation. No grease, oil, or any lubricant is required, which eliminates maintenance and contamination risks. -
Q4: What types of misalignment can this coupling accommodate?
A: It can handle angular misalignment up to 1°, parallel misalignment up to 0.5 mm, and axial misalignment up to ±2 mm (double disc version offers higher capacity). -
Q5: Is the disc customizable for non-standard bore sizes?
A: Absolutely. We offer complete customization of bore size, outer diameter, thickness, and keyway dimensions. Just provide your shaft specifications, and we will produce the disc accordingly. -
Q6: What is the typical lead time for custom orders?
A: For standard customizations, lead time is 15–20 working days. For complex designs, it may extend to 30 days. We can also expedite orders for urgent projects. -
Q7: Does the coupling disc require any special installation tools?
A: No. The disc uses standard clamping hubs that can be installed with basic hand tools. Alignment is straightforward due to the disc’s flexible nature. -
Q8: What certifications does your company hold?
A: Our company is ISO9001 certified. We also comply with international quality standards. If you require specific certifications (e.g., CE, RoHS), please inform us, and we can discuss availability.
