Hebei Speed Torque Transmission Technology Co., Ltd. proudly presents our Industrial Ball Cage CV Joint Coupling — a high-performance power transmission solution specifically engineered for the demanding environments of metallurgical equipment, oil drilling operations, and ship transport machinery. With over 6 years of manufacturing experience (est. 2017) and a modern factory spanning 3,000–5,000 square meters, we combine precision engineering with robust construction to deliver couplings that excel under heavy loads, high speeds, and extreme misalignment conditions. Our products are trusted by clients across North America, South America, Eastern Europe, Southeast Asia, and more, with an annual export value of US$5–10 million.
Key Features & Technical Advantages
Ball Cage Design: Utilizes precision-ground steel balls retained in a hardened cage, enabling smooth torque transmission at constant velocity even under angular misalignment up to 15° (optional 25°).
High Torque Density: Compact structure transfers up to 50,000 Nm of torque with minimal backlash, ideal for heavy-duty metallurgical rolling mills and drilling rigs.
Durable Materials: Constructed from 20CrMnTi alloy steel (or equivalent) with case-hardened surfaces (HRC 58–62) for exceptional wear resistance and fatigue life.
Sealed Lubrication System: Pre-filled with high-temperature grease and equipped with double-lip oil seals to prevent leakage and contaminant ingress, ensuring maintenance-free operation for extended periods.
Customizable Interfaces: Available with keyways, splines, flanges, or custom bore diameters to match your existing shafts and equipment.
Low Vibration & Noise: Optimized ball track geometry reduces noise levels below 75 dB(A) under rated conditions, enhancing workplace safety and machine longevity.
Corrosion Protection: Standard surface treatment options include black oxide, phosphating, or zinc plating suitable for humid marine environments.
Technical Specifications (Sample Models)
| Model | Rated Torque (Nm) | Max. Speed (rpm) | Angular Offset (°) | Bore Range (mm) | Weight (kg) |
|---|---|---|---|---|---|
| BCC-10 | 1,200 | 3,000 | 12 | 20–50 | 8.5 |
| BCC-25 | 6,000 | 2,000 | 15 | 50–100 | 22.0 |
| BCC-50 | 24,000 | 1,200 | 10 | 80–160 | 65.0 |
| BCC-100 | 50,000 | 800 | 8 | 120–200 | 145.0 |
Note: Custom models with extended angle capacity (up to 25°) and higher torque ratings are available upon request.
Benefits for Your Application
For Metallurgical Equipment: Handles high shock loads and temperature variations in steel rolling mills, continuous casting machines, and furnace drives. The sealed design resists scale and dust ingress.
For Oil Drilling: Withstands torsional vibrations and severe misalignment from drill string dynamics. Optional high-angle variants accommodate rig floor and top drive connections.
For Ship Transport: Corrosion-resistant coatings and compact envelope make it suitable for propeller shafts, steering gear, and cargo pump drives in marine environments.
Reduced Maintenance: Pre-lubricated and sealed for life (or relubricatable) — typical service intervals exceed 8,000 operating hours under normal conditions.
Easy Installation: Precision-machined mating surfaces and alignment guides allow quick retrofit without shaft modification in most cases.
Cost Efficiency: Lower total cost of ownership compared to gear couplings or universal joints due to fewer wear parts and longer service life.

With a dedicated team of 101–200 experienced personnel, we produce over 10,000 couplings annually and export to North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and across Europe and Asia. Our annual export value of US$5–10 million reflects the trust global customers place in our products. We ship from major ports including Shanghai, Tianjin, and Qingdao, providing flexible logistics solutions. Every coupling undergoes torque and angle testing before leaving our facility, and we offer 24-month warranty against manufacturing defects. Contact our sales team today to discuss your specific shaft coupling requirements — we will provide a customized drawing and quotation within 48 hours.
Frequently Asked Questions (FAQ)
Q1: What is the maximum angular misalignment your ball cage CV joint coupling can handle?
Standard models operate with up to 15° angular offset. For applications requiring extreme angles (e.g., steering systems), we can supply custom designs with up to 25° misalignment capacity. Please specify your requirement during inquiry.
Q2: How often does the coupling require lubrication?
Our standard couplings are pre-lubricated with high-temperature grease and sealed for life, requiring no routine lubrication under normal operating conditions. For relubricatable versions (optional), intervals typically range from 6 to 12 months depending on speed and load.
Q3: Can this coupling replace an existing gear coupling or universal joint without modifying the shaft?
In most cases yes. We offer multiple connection types — keyway, spline, flange, or custom bore. Provide your shaft dimensions and existing coupling interface, and we will match it. Minor adaptors may be suggested if needed.
Q4: What materials are used and is corrosion protection available for marine use?
The primary material is 20CrMnTi alloy steel with case hardening. We apply surface treatments such as black oxide, phosphating, or zinc plating as standard. For aggressive marine environments, optional duplex coating (zinc-nickel + sealant) is available on request.
Q5: How does the ball cage coupling compare to a typical jaw coupling in terms of torque capacity?
Ball cage CV joint couplings generally handle significantly higher torque and allow greater angular misalignment than jaw couplings. They are designed for heavy industrial drives where jaw couplings would fail due to overload or shaft offset.
Q6: What is the lead time for custom orders?
Standard models ship within 7–15 days. Custom designs (special bore, angle, length) typically require 20–30 days after drawing approval. Urgent requests can be expedited (contact our sales team).
Q7: Do you have certifications or test reports for your couplings?
Yes, our factory is ISO9001:2015 certified. We provide material certificates and torque test reports for each batch upon request. Additional third-party inspection (e.g., SGS, BV) can be arranged.
Q8: Can I get a sample before placing a bulk order?
Yes, sample orders are welcome. A small tooling fee may apply for customized samples, which is refundable for bulk orders. Sample lead time is about 15–20 working days.
