Hebei Speed Torque Transmission Technology Co., Ltd. proudly presents the BJ-C Flange Ball Cage Universal Coupling — a high-performance equal speed drive shaft engineered for precision roller transmission in metallurgy applications. With over 7 years of manufacturing excellence and a 3,000-5,000 m² facility, we combine advanced machining technology with strict quality control to deliver couplings that ensure stable torque transmission, minimal backlash, and long service life. This product is designed to meet the rigorous demands of heavy-duty industrial environments where reliability and accuracy are paramount.
Key Features & Technical Specifications
- Equal Speed (Constant Velocity) Design: The ball cage structure ensures smooth power transmission at constant angular velocity, reducing vibration and noise even at high speeds or misaligned angles.
- Flange Connection: Robust flange mounting allows easy installation and disassembly, ideal for systems requiring frequent maintenance or shaft alignment adjustments.
- High Torque Capacity: Manufactured from high-strength alloy steel (40Cr or equivalent) with heat treatment, providing excellent torsional strength and fatigue resistance.
- Precision Roller Transmission: Optimized for metallurgy rolling mills, conveying lines, and other precision roller drives where consistent speed and torque are critical.
- Angle Compensation: Allows up to 15° angular misalignment per joint, accommodating shaft deflection and installation tolerances without affecting performance.
- Customizable Dimensions: Bore diameter, flange size, and overall length can be tailored to your specific application requirements.

Frequently Asked Questions
-
Q: What is the maximum operating temperature for this coupling?
A: The standard version can operate in temperatures from -20°C to +80°C. For higher temperatures (up to 200°C), please consult us for special materials or coatings. -
Q: Can I get a custom bore size or flange pattern?
A: Yes, we offer customization for bore diameter, keyway, flange bolt pattern, and overall length. Please provide your drawings or specifications. -
Q: How do I determine the correct size for my application?
A: We recommend calculating the required torque, speed, and misalignment angle. Our technical team can help you select the ideal model based on your motor power and load conditions. -
Q: Does this coupling require lubrication?
A: The ball cage joint is pre-lubricated with high-temperature grease and is maintenance-free under normal conditions. However, for extreme environments, periodic re-lubrication may be needed. -
Q: What is the typical lead time for standard sizes?
A: For standard stock sizes, lead time is 7–15 days. Custom orders typically take 20–30 days, depending on complexity and quantity. -
