Hebei Speed Torque Transmission Technology Co., Ltd. (established 2017, factory area 3,000–5,000 m², annual export value US$5–10 million) brings you our High Synchronous Ball Cage CV Coupling — engineered for precise power transmission in heavy industrial equipment. With ISO9001 quality management system certification and a dedicated team of 101–200 employees, we deliver consistent performance and reliability across global markets including North America, Europe, Southeast Asia, and Oceania.
This CV coupling is designed to maintain constant velocity and synchronous rotation even under high torque and severe misalignment conditions. The advanced ball cage design minimizes friction, reduces wear, and ensures smooth operation in demanding environments such as steel mills, mining conveyors, and heavy-duty presses. Our couplings are available from Shanghai, Tianjin, and Qingdao ports, with customizable dimensions and coatings to meet your specific application requirements.
Key features include:
- High Synchronization – Precision-ground inner and outer races paired with hardened steel balls guarantee zero phase lag and uniform torque transmission.
- Heavy-Duty Construction – Made from high-strength alloy steel (20CrMnTi or 40Cr) with heat treatment for enhanced durability.
- Compact Design – Ball cage structure allows longer service life and lower inertia compared to traditional universal joints.
- Sealed Lubrication System – Pre-greased and fully sealed to resist dust, moisture, and contaminants, reducing maintenance intervals.
- Flexible Mounting Options – Available with flange, spline, or keyway connections to fit existing shafts.

| Articulation Angle | Up to 15° (dynamic) / 20° (static) |
| Outer Diameter Range | 50 mm – 150 mm |
| Shaft Diameter | 20 mm – 80 mm (custom fits available) |
| Material Hardness | HRC 58–62 (after carburizing and quenching) |
| Surface Treatment | Phosphating, black oxide, or zinc plating (optional) |
Benefits for your heavy industrial equipment:
- Eliminates torsional vibration and noise, improving operator comfort and machine accuracy.
- Reduces downtime — sealed design extends grease life up to 8,000 hours under normal conditions.
- Easy to retrofit — compatible with standard SAE, DIN, or JIS shaft configurations.
- Cost-effective solution — lower total cost of ownership compared to gear couplings or chain couplings.
Our production facility in Cangzhou, Hebei, spans 3,000–5,000 m² and is equipped with advanced CNC machining centers, heat treatment lines, and precision measuring instruments. Every coupling undergoes 100% dimensional inspection and torque testing before shipping. With over US$5 million annual export value and shipments to 15+ countries, we have built a reputation for reliability and on-time delivery.
Whether you need a standard model or a custom-engineered solution, our engineering team is ready to support you. Contact us today for a quote or technical consultation. Let Hebei Speed Torque power your heavy equipment with precision and reliability!
Frequently Asked Questions
Q: Can this CV coupling be used in continuous operation at high speed?
A: Yes, our couplings are designed for continuous duty up to 3000 RPM. For higher speeds, please consult our engineers — we offer dynamic balancing options.
Q: What is the maximum misalignment angle allowed?
A: The coupling can articulate up to 15° during operation and up to 20° when stationary. Exceeding these limits may cause accelerated wear.
Q: Are the couplings pre-lubricated and maintenance-free?
A: They are factory-filled with high-temperature grease and sealed. Under normal conditions they require no maintenance for the first 5,000 hours. Relubrication can be performed through optional grease fittings.
Q: Can I get a coupling with a spline or keyway connection?
A: We offer flange, spline, keyway, and custom connection types — please specify your shaft dimensions when ordering.
Q: What is the typical lead time for a custom order?
A: For standard sizes, lead time is 15–20 working days. Custom sizes may require 25–35 working days depending on complexity.
Q: Do you provide samples for testing?
A: Yes, we can provide sample units for evaluation. Sample cost and shipping are negotiable; production orders can be placed after approval.
Q: Is there a warranty on this product?
A: We offer a 12-month warranty from date of shipment against manufacturing defects. Extended warranty options are available upon request.
Q: Which shipping ports do you use?
A: We ship from Shanghai, Tianjin, and Qingdao ports. Sea, air, and express courier options are available.
