Product Description
High Precision Universal Joint Coupling – Single & Double Structure for Farm and Construction Industries
Factory direct | 42CrMo alloy steel | Single (UJMA) or double (UJMB) joint | 4.5–1500 N·m torque | 6–50 mm bore | H7 precision | Keyway/hexagon/square hole options | ISO9001 & BV certified | OEM/ODM/OBM
The Apexcoupling High Precision Universal Joint Coupling is a heavy-duty power transmission component engineered for the demanding conditions of farm and construction machinery. Available in single joint and double joint configurations, this coupling transmits rotary motion between non-aligned shafts with exceptional reliability and minimal backlash. Constructed from 42CrMo alloy steel with H7 precision bore, it delivers high torque capacity (4.5–1500 N·m), excellent fatigue resistance, and long service life. With 45° angular misalignment capacity per joint and custom hole options (keyway, hexagon, square), this coupling is the ideal solution for tractors, harvesters, excavators, loaders, conveyors, and PTO drive systems.
✅ Designed for harsh agricultural and construction environments. Single or double joint configuration. 42CrMo alloy steel – high strength and durability. 4.5–1500 N·m torque range – covers light to heavy-duty applications.

Single Joint vs Double Joint – Which One Do You Need?
| Feature | Single Joint | Double Joint |
|---|---|---|
| Angular misalignment | ✅ Up to 45° | ✅ Up to 45° per joint |
| Parallel offset | ❌ No | ✅ Yes |
| Total articulation | Up to 45° | Up to 90° |
| Length | Shorter | Longer |
| Best for | Shafts intersecting at an angle on the same plane | Shafts both angled and offset |
Rule of thumb for farm and construction:
Use single joint for straight PTO connections with slight angular misalignment.
Use double joint for connecting shafts that are both angled and offset – common in harvesters, loaders, and excavators.
💡 Double joint configurations provide smoother power transmission and reduced vibration when both angular and parallel misalignment are present.

FAQ
Q: What is a universal joint coupling?
A: A universal joint coupling (also called a U-joint, cardan joint, or Hooke’s joint) is a mechanical component that connects two non-aligned shafts, transmitting rotary motion and torque even when the shafts are at an angle to each other.
Q: What is the difference between single and double joint?
A: Single joint provides angular flexibility only (up to 45°). Double joint provides both angular flexibility and parallel offset capability, allowing access to applications where shafts are both angled and offset.
Q: What is the maximum operating angle?
A: Each joint can operate up to 45°. For continuous operation, we recommend keeping the angle below the maximum to extend service life.
Q: What materials are available?
A: Standard material is 42CrMo alloy steel – high strength, toughness, and fatigue resistance. Other materials available on request.
Q: What is the bore tolerance?
A: Standard finished bore tolerance is H7 for precision shaft fit.
Q: What bore types can I get?
A: We offer keyway, hexagon hole, square hole, and plain hole. Custom bore types accepted.
Q: What is the torque range?
A: The series covers 4.5 – 1500 N·m. Custom higher torque available on request.
Q: Is this coupling suitable for agricultural machinery?
A: Absolutely. Designed specifically for farm and construction equipment, with 42CrMo construction to withstand harsh conditions.
Q: Can I get a custom coupling?
A: Yes. We offer OEM, ODM, and OBM support – custom bores, materials, and configurations available.
