Product Structure

1. 304 Stainless Steel Body – Precision-machined from premium SUS304 stainless steel, providing excellent corrosion resistance, durability, and long service life in harsh environments.

2. Precision H7 Bore – Ground to H7 tolerance for accurate shaft fit, reducing vibration and ensuring smooth power transmission.

3. Set Screw Fastening – M5 set screw provides secure shaft fixation, preventing slippage under load.

4. Single Joint Design – Accommodates angular misalignment up to 45° per joint, ideal for shafts with slight offset.

5. Cross Shaft Assembly – Precision-machined cross shaft with plain bearing or needle roller bearing options for smooth rotation and extended service life.

💡 How it works: The 304 stainless steel single universal joint coupling connects two shafts that are not perfectly aligned. The cross shaft assembly allows angular misalignment up to 45° per joint while transmitting torque and rotational motion. The set screw fastening securely locks the coupling to the shafts, while the H7 precision bore ensures accurate shaft fit and concentricity. The 304 stainless steel construction provides excellent corrosion resistance for demanding environments.

Connection Types – Choose Your Configuration

The 304 stainless steel universal joint coupling is available in multiple connection types to suit your specific application:

✅ Ordering Example: For a Type B (keyway + set screw) single joint with 10mm bores on both ends, specify: 02G(B10) – where 02G is the specification, B is the type, and 10 is the bore diameter.

FAQ

Q: What is a universal joint coupling?
A: A universal joint coupling (also called a U-joint or cardan joint) is a mechanical coupling that connects two shafts, allowing them to transmit torque even when they are not perfectly aligned. It accommodates angular misalignment while maintaining smooth power transmission.

Q: What is the advantage of 304 stainless steel?
A: 304 stainless steel offers excellent corrosion resistance, making it ideal for applications exposed to moisture, chemicals, and harsh environments. It also provides good strength, durability, and wear resistance.

Q: What is the maximum operating angle?
A: This single universal joint coupling accommodates up to 45° angular misalignment per joint. Double joint configurations can achieve up to 90° total articulation.

Q: What is the bore tolerance?
A: The standard bore tolerance is H7, providing a precision fit for accurate shaft alignment and reduced vibration.

Q: What connection types are available?
A: We offer Type A (pin hole + circlip slot), Type B (keyway + set screw), Type C (square hole), and Type D (hexagon hole). Choose based on your application requirements.

Q: Is the coupling corrosion-resistant?
A: Yes. Made from 304 stainless steel with oxide finish, this coupling is highly resistant to moisture, chemicals, and oxidation – suitable for food, packaging, and outdoor applications.

Q: What are the common applications?
A: Food & beverage machinery, packaging equipment, conveyor systems, industrial machinery, automation equipment, medical devices, and printing machinery.

Q: Can I get a custom coupling?
A: Yes. We offer OEM, ODM, and OBM customization – custom bores, lengths, keyways, connection types, and finishes available.

Q: What is the warranty?
A: 1 Year – quality assured.

Q: What is the lead time?
A: Stock items ship immediately. Custom orders typically require 7-15 days.
