Welcome to Hebei Speed Torque Transmission Technology Co., Ltd. – your trusted partner for high-performance transmission solutions. Since our founding in 2017, we have dedicated ourselves to manufacturing Flexible Ball Cage Universal Couplings that meet the rigorous demands of textile machinery and various industrial applications. Our ISO9001 certified factory spans 3,000–5,000 square meters, with an annual export value of US$5 Million–US$10 Million, serving clients across six continents including North America, South America, Europe, Southeast Asia, and Africa. With a team of 101–200 skilled employees, we combine precision engineering with cost-effective production to deliver couplings that ensure smooth power transmission, reduce downtime, and extend equipment life.
Our Flexible Ball Cage Universal Coupling is designed to accommodate angular, parallel, and axial misalignments while transmitting torque efficiently. The innovative ball cage structure provides exceptional flexibility and self-aligning capability, making it ideal for shafts that experience dynamic alignment changes during operation. Whether you are upgrading existing textile machines or building new industrial systems, this coupling offers reliable performance under demanding conditions.
Key Features & Benefits
- Ball Cage Design – Provides up to 25° of angular misalignment compensation, reducing stress on bearings and shafts, which extends the life of connected equipment.
- High Strength Materials – Constructed from premium alloy steel or optional stainless steel, ensuring durability in harsh industrial environments (dust, moisture, high temperature).
- Low Maintenance – The self-lubricating ball cage reduces wear and eliminates the need for frequent greasing, saving maintenance time and cost.
- Vibration Damping – The flexible design absorbs shock loads and torsional vibrations, protecting sensitive textile machinery components like spindles and rollers.
- Easy Installation – Precisely machined bores and keyways allow quick fitting; available with set screws or clamping hubs for secure mounting.
- Customizable Options – Bore diameters, overall length, and material can be tailored to match specific shaft configurations and torque requirements.
- Wide Application – Perfect for textile spinning, weaving, dyeing machines, as well as pumps, compressors, conveyors, and other industrial drives.

Frequently Asked Questions (FAQ)
1. What is the main advantage of a ball cage coupling over other flexible couplings?
The ball cage design offers higher angular misalignment capacity (up to 25°) while maintaining smooth torque transmission. It also self-aligns, reducing bearing loads and extending component life. Compared to elastomeric or metallic bellows couplings, it provides better compensation for dynamic misalignments common in textile machinery.
2. Can this coupling be used in high-temperature environments in textile dyeing machines?
Yes. Standard materials can operate up to 120°C. For higher temperatures (e.g., up to 250°C), we can supply couplings made from heat-treated stainless steel or special coatings. Please specify your temperature range when ordering.
3. What maintenance is required for this coupling?
The ball cage is designed for low maintenance – the bearings are pre-lubricated and sealed. Periodic visual inspection and cleaning of the outer surface are usually sufficient. In most applications, no re-greasing is needed during the service life. However, if operated in extreme dust or corrosive conditions, occasional lubrication of the ball cage may extend life.
4. Do you offer custom bore sizes and keyways?
Absolutely. We can machine the bore to any diameter within our range (6 mm to 100 mm standard, up to 150 mm on request). Keyways, set screws, or clamping hubs can be added per your specifications. Custom balancing is also available for high-speed applications.
5. How does the coupling handle parallel misalignment?
The flexible ball cage can accommodate parallel misalignment up to 2 mm (depending on size). For larger offsets, we recommend using a double-cardan style or consult our engineering team for a custom solution.
6. What is the typical delivery time for standard models?
For standard sizes and black oxide finish, lead time is around 15–25 working days. Custom designs may require 30–40 days. We ship via sea or air from Shanghai, Tianjin, or Qingdao. Express delivery (DHL, FedEx) is available for small orders.
7. Is your company ISO9001 certified? How do you ensure quality?
Yes, our entire production process, from raw material inspection to final assembly, is ISO9001 certified. Each coupling undergoes dimensional checks, hardness testing, and dynamic balancing before packaging. We also provide a one-year warranty against defects in materials and workmanship.
8. Can I get a sample before placing a bulk order?
Of course. We offer sample orders (single piece or small quantities) at a reasonable price. Sample delivery typically takes 5–7 days via express courier. Once you approve the quality, we can proceed with mass production.
