Double Universal Joint (Plain Bore) – High Angle Flexible Couplings

Looking for a precision-engineered double universal joint for high-angle shaft transmission? At BEP Ltd, we supply high-quality double universal joint couplings (plain bore / unbored) designed for smooth torque transfer where significant angular or parallel misalignment exists.

Our double universal joints are ideal for industrial machinery, driveshaft systems, automation equipment, and mechanical assemblies requiring flexibility and reliable power transmission.

What Is a Double Universal Joint?

A double universal joint coupling consists of two universal joints connected by an intermediate center section. This design allows:

• Higher operating angles than a single joint
• Improved compensation for angular misalignment
• Parallel offset correction
• Smoother torque transmission

With two bending points, these joints can operate at angles up to 90° (application dependent) and handle shaft misalignment typically between 0° and 45°.

The plain bore (unbored) version allows custom machining to suit specific shaft diameters and keyway requirements.

Material Options & Performance Comparison

Material selection depends on torque load, environmental exposure, operating temperature, and speed requirements.

Benefits of Using Double Universal Joint Couplings

• Greater angular flexibility than single joints
• Compensation for parallel shaft offset
• Smooth and efficient torque transmission
• Reduced vibration in misaligned systems
• Cost-effective solution for complex shaft alignment

In many industrial applications, joints double groove compatible systems provide improved mechanical stability and operational efficiency.

Frequently Asked Questions (FAQs)

1. What is the advantage of a double universal joint over a single joint?

A double joint handles higher operating angles and compensates for both angular and parallel misalignment more effectively.

2. What does plain bore (unbored) mean?

Plain bore means the joint does not have a finished bore, allowing it to be machined to specific shaft dimensions.

3. Can double universal joints operate at 90 degrees?

Yes, depending on configuration and load conditions, they can operate at high angles up to 90°.

4. Which material should I choose?

Steel is best for high torque and heavy-duty applications, while plastic is suitable for corrosion-resistant and lightweight systems.
