Welcome to Hebei Speed Torque Transmission Technology Co., Ltd. – your trusted partner for high-performance power transmission components. Our Cardan Shaft, Universal Joint, Shaft Coupling, and Universal Coupling for Rolling Mill are engineered to deliver exceptional torque transmission and angular flexibility under extreme operating conditions. With over 7 years of manufacturing experience, a 3,000–5,000 m² factory, and a dedicated team of 101–200 professionals, we provide reliable solutions that keep your rolling mill running efficiently and safely.
These couplings are specifically designed to withstand heavy loads, high temperatures, and continuous operation in steel rolling applications. They feature precision-machined components, robust alloy steel construction, and advanced heat treatment processes to ensure long service life and minimal maintenance. Whether you need a standard design or a fully customized solution, our engineering team can meet your exact requirements.
Key Features & Benefits
High Torque Capacity: Our couplings transmit up to 500,000 Nm, suitable for large rolling mills.
Wide Angular Flexibility: Each joint allows up to 15° misalignment, reducing stress on connected equipment.
Durable Construction: Made from forged alloy steel with induction-hardened bearing surfaces for extended wear life.
Low Maintenance: Grease-lubricated cross bearings and sealed design reduce downtime.
Customizable Dimensions: Length, bore diameter, flange type, and keyway can be tailored to your mill specifications.
ISO9001 Certified: Our quality management system ensures consistent product performance and traceability.
Quick Delivery: With annual export value of US$5–10 million, we ship globally from Shanghai, Tianjin, or Qingdao ports.

Frequently Asked Questions (FAQ)
Q: What is the typical lifespan of a cardan shaft in a rolling mill?
A: With proper lubrication and alignment, our shafts can last 3–5 years under normal operating conditions. Regular inspection of bearing clearances and wear patterns is recommended.Q: Can you provide custom flange configurations?
A: Yes. We can produce flanges according to your existing mill standards (DIN, ANSI, or custom drawings). Just provide the bolt pattern and pilot diameter.Q: How do I determine the correct length and torque rating?
A: Our technical team can calculate based on your motor power, mill RPM, and installation distance. Please share your working parameters for a free proposal.Q: Do you supply spare parts separately?
A: Absolutely. We offer individual cross kits, bearings, and yokes for easy on-site replacement.Q: What is the maximum operating angle for your universal joint?
A: Each joint can handle up to 15° at zero torque. Under full load, we recommend staying below 5° for optimal bearing life.Q: Is heat treatment included in the standard product?
A: Yes. All yoke and shaft components are quenched and tempered, with induction hardening on bearing journals for extra wear resistance.Q: What certifications do you have?
A: Our company is ISO9001:2015 certified. We can also provide material certificates and test reports upon request.Q: How long does it take to produce a custom order?
A: Generally 30–45 working days after drawing approval. For urgent needs, please contact our sales team for expedited options.
