Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017, is a professional manufacturer dedicated to high‑quality transmission components. Our Heavy Duty Universal Coupling (also referred to as Universal Shaft) is engineered for the most demanding machinery and equipment applications. With a factory spanning 3,000 – 5,000 m² and ISO9001 certification, we ensure every unit is precisely manufactured to deliver reliable performance and long service life. This coupling provides exceptional torque transmission, angular compensation, and durability, making it an ideal choice for industries such as mining, metallurgy, construction, and heavy machinery.
Our universal coupling is designed with the following key features and advantages:
High‑Strength Material – Constructed from premium alloy steel or carbon steel, heat‑treated to enhance hardness and wear resistance, ensuring long‑term reliability under heavy loads.
Precision Machining – CNC‑machined components guarantee tight tolerances and smooth operation, minimizing vibration and noise even at high rotational speeds.
Versatile Configurations – Available in single, double, and cross‑type designs to accommodate various shaft misalignment and torque requirements.
Customizable Options – Bore diameter, length, flange type, and surface treatment can be tailored to specific customer needs (e.g., galvanized, phosphated, or painted coating).
Low Maintenance – Grease‑lubricated bearing cups and sealed covers reduce upkeep frequency, saving time and operational costs.
Wide Application Range – Suitable for rolling mills, pumps, compressors, conveyors, paper machines, and other industrial equipment requiring reliable power transmission.

Frequently Asked Questions (FAQ):
Q: What materials are used in your universal couplings?
A: We use premium alloy steel (e.g., 40Cr, 42CrMo) or carbon steel (e.g., 45#) with heat treatment and surface hardening to ensure high strength and wear resistance.Q: Are your products ISO certified?
A: Yes, our manufacturing facility is ISO9001 certified, and we maintain consistent quality throughout production.Q: Can I get a custom bore diameter or length?
A: Absolutely. We offer customization for bore size, overall length, flange pattern, and coating. Please provide your drawing or specifications for a precise quote.Q: What is the maximum torque your coupling can handle?
A: Our standard range covers 1,000 – 50,000 Nm. For higher torque requirements, we can design customized solutions upon request.Q: How do I select the right coupling for my application?
A: Consider the torque, shaft diameter, misalignment type (angular/parallel), and operating speed. Our engineering team can assist you in selecting the optimal model.Q: What is the typical lead time?
A: For standard models, lead time is 15 – 30 working days. Custom orders may take 25 – 40 days depending on complexity. Express delivery is available for urgent orders.Q: Do you provide warranty and after‑sales support?
A: Yes, we offer a 12‑month warranty against manufacturing defects. Technical support and replacement parts are available throughout the product life.Q: How is the coupling packaged for export?
A: Each unit is individually wrapped with anti‑rust paper, then packed in wooden crates or pallets to ensure safe transit. We follow international export standards.
