JK JQ JQW Clamping Sleeve Coupling

It firmly clamps the two half couplings at the ends of the two connected shafts through clamping force, achieving torque transmission. Youdaoplaceholder0 can complete axial disassembly and assembly ‌ without moving the equipment, making it particularly suitable for small and medium-sized equipment with limited space or frequent maintenance requirements (such as pumps, fans, agitators, etc.). This coupling has a compact structure, is easy to install and disassemble, and features ‌ high torsional rigidity ‌. However, due to the lack of elastic elements, it is necessary to strictly ensure the alignment accuracy of the two shafts, and its ability to compensate for radial displacement is limited. It is often used in light to medium load transmission applications with low vibration and good alignment. Its common materials are steel or aluminum alloy, which can cover a wide range of torque.

1.Clamping structure design

It is composed of two completely symmetrical steel semi-cylindrical clamps, which are fastened along the axial direction by high-strength bolts to form a 360° wrap around the shaft end.

Youdaoplaceholder0 can be disassembled and assembled without axial movement of the equipment‌, making it particularly suitable for scenarios with limited space or frequent maintenance requirements (such as pumps, fans, and conveyor belts).

2.Rigid transmission, zero backlash

There are no elastic components. Metal is directly bonded. When transmitting torque, there is no torsional gap‌, ensuring high-precision synchronous transmission.

3.Compact structure and wide torque range

The structure is simple and compact. The volume is smaller than that of the elastic coupling of the same torque‌, saving installation space.

The torque range covers from 10Nm to 15,000 Nm, meeting the requirements of light load to medium and heavy load.

4.Easy maintenance

When replacing, only loosen/tighten the bolts. Youdaoplaceholder0 can be disassembled and assembled by a single person within 10 minutes ‌, significantly reducing downtime.

No lubrication is required and the maintenance-free design reduces long-term operation and maintenance costs.
