Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017 with a factory spanning 3,000-5,000 square meters and a dedicated team of 101-200 professionals, presents our Precision Double Disc Shaft Coupling for Turbine – Customized Design. This high-performance coupling is engineered to deliver exceptional power transmission accuracy, compensates for misalignment, and reduces vibration in demanding turbine applications. With an annual export value exceeding US$5 million and serving markets across North America, Europe, Asia, and beyond, our coupling is trusted by global clients for its reliability and precision.
Our double disc coupling features a unique, patented disc pack design that provides high torsional stiffness while accommodating angular, parallel, and axial misalignments. The all-metal construction ensures zero backlash, making it ideal for precise positioning systems in turbine generators, compressors, and pumps. Each unit is custom-designed to match your specific shaft dimensions, torque requirements, and operating conditions, ensuring a perfect fit for your application.
Key Features & Technical Specifications:
- High Precision: Balanced to G6.3 standard (G2.5 available upon request) for minimal vibration at high speeds up to 10,000 rpm.
- Customizable Design: Bore diameters, keyways, overall length, and disc pack material (stainless steel or alloy steel) are tailored to your specifications.
- Zero Backlash: The metal disc pack eliminates clearance, ensuring accurate torque transmission without hysteresis.
- Maintenance-Free Operation: No lubrication required; robust design offers long service life even in harsh environments.
- Misalignment Compensation: Accommodates angular misalignment up to 1°, parallel misalignment up to 0.5 mm, and axial movement up to ±2 mm (depending on size).
- High Torque Capacity: Designed for torque ranges from 100 Nm to over 50,000 Nm, with custom options available.

Why Choose Our Precision Double Disc Shaft Coupling? The design is optimized for turbine applications where reliability and precision are paramount. Unlike traditional elastic couplings, our double disc coupling offers superior positioning accuracy and eliminates the need for frequent maintenance. The customized design ensures that the coupling matches your exact shaft spacing, bore sizes, and torque requirements, reducing installation time and improving overall system efficiency. Additionally, the all-metal construction provides excellent resistance to temperature extremes, corrosive environments, and high rotational speeds. Our engineering team works closely with clients to select the optimal disc pack configuration, surface treatment (e.g., black oxide, zinc plating, or passivation), and balance grade to meet specific performance goals.
Quality Assurance & Trust: Hebei Speed Torque Transmission Technology Co., Ltd. is ISO9001 certified, ensuring that every coupling undergoes rigorous quality control from raw material inspection to final dynamic balancing. Our factory, located in Cangzhou, Hebei, operates with advanced CNC machining centers and testing equipment. With an annual export value of US$5-10 million and a team of over 100 skilled employees, we have supplied couplings to turbine manufacturers, power plants, and industrial equipment OEMs across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and other regions. We ship from major ports including Shanghai, Tianjin, and Qingdao, offering flexible logistics solutions. Our commitment to customized precision and timely delivery has earned us long-term partnerships with clients worldwide.
We invite you to contact us for a custom quotation or technical consultation. Provide your shaft dimensions, torque requirements, operating speed, and any special conditions, and our engineers will deliver a tailored coupling solution that exceeds your expectations. Experience the difference of precision engineering from a trusted manufacturer.
Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for a customized double disc coupling?
A: For standard custom designs, lead time is approximately 15-25 working days after receiving all specifications. Rush orders can be arranged upon request. -
Q: Can you provide couplings for high-speed turbine applications above 10,000 rpm?
A: Yes, we can design discs and balance them to G2.5 grade for speeds up to 20,000 rpm, depending on bore size and disc diameter. Please consult our engineers. -
Q: Do you offer different disc pack materials besides stainless steel?
A: Yes, we offer alloy steel (e.g., 40Cr, 42CrMo) with surface treatments, as well as customized materials like Hastelloy or Inconel for extreme environments. Contact us for options. -
Q: How do you ensure the coupling is properly balanced for my application?
A: We perform dynamic balancing on all couplings after assembly, using precision balancing machines. The balance grade is validated per your specification (G6.3 or G2.5). -
Q: Is there a minimum order quantity (MOQ) for customized couplings?
A: No, we accept single-piece custom orders. However, quantity discounts are available for larger volumes. -
Q: Can you provide a drawing or CAD model before production?
A: Yes, we will provide a 2D/3D drawing for your approval before manufacturing. This ensures the design matches your requirements. -
Q: What is the warranty period for your couplings?
A: Our standard warranty is 12 months from the date of shipment, covering defects in material and workmanship. Extended warranty options are available upon request.
