A universal joint, often abbreviated as U-joint, is a mechanical device used to connect two shafts that are not in a straight line, allowing for the transmission of rotary motion between them at various angles. It is a critical component in many industries, including automotive, aerospace, marine, and industrial machinery, due to its ability to accommodate misalignment and provide smooth power transfer.
Our universal joints are engineered with precision to meet high standards of durability and performance. Below are the detailed specifications presented in lists and tables for clarity.

Universal joints are versatile and used in various applications, such as:
What is the primary function of a universal joint?
The primary function is to transmit rotary motion between two shafts that are not aligned, allowing for angular misalignment while maintaining constant velocity in some designs.
How do I choose the right universal joint for my application?
Consider factors such as torque requirements, operating angle, rotational speed, environmental conditions (e.g., temperature and corrosion), and dimensional constraints. Refer to the product parameters tables above for guidance, and consult with engineering specifications if needed.
What maintenance does a universal joint require?
Most modern universal joints are pre-lubricated and sealed for life, requiring minimal maintenance. However, in high-stress applications, periodic inspection for wear, lubrication (if applicable), and replacement of worn parts is recommended to ensure optimal performance.
Can universal joints handle high-speed rotations?
Yes, but it depends on the design and materials. Our universal joints can operate at speeds up to 5000 RPM, but always check the specific product specifications to ensure compatibility with your application's speed requirements.
What is the difference between a single and double universal joint?
A single universal joint consists of two yokes connected by a cross piece, allowing flexibility in one plane. A double universal joint, or constant velocity joint, uses two joints to maintain constant velocity and reduce vibrations, ideal for applications requiring smoother operation at higher angles.
Are universal joints resistant to corrosion?
Yes, our universal joints feature surface treatments like zinc plating or phosphating to provide excellent corrosion resistance, making them suitable for harsh environments, including marine and outdoor industrial settings.
What is the maximum operating angle for a universal joint?
The maximum operating angle typically ranges up to 45 degrees, but this can vary based on the joint design. Exceeding the recommended angle may reduce efficiency and lifespan, so always adhere to the manufacturer's guidelines.
How do I install a universal joint properly?
Ensure the shafts are clean and aligned within the specified angle range. Use appropriate tools to secure the joint, avoiding over-tightening. For detailed instructions, refer to the product manual or seek professional assistance to prevent damage.
