About this product

Product information from the supplier.

The JK JQ JQW Clamping Sleeve Coupling is a high-precision engineering solution designed for rigid torque transmission between two connected shafts. Utilizing a robust clamping force, it securely bonds the half couplings to the shaft ends, ensuring a stable and reliable power transfer. This series is specifically engineered for applications where high torsional rigidity and synchronous transmission are paramount, eliminating the backlash typically found in elastic couplings.

Designed for efficiency and versatility, these couplings allow for axial disassembly and assembly without the need to move surrounding equipment. This unique feature makes them an ideal choice for small to medium-sized machinery operating in confined spaces or environments requiring frequent maintenance, such as industrial pumps, fans, and agitators. Available in premium steel or aluminum alloy, they provide a wide torque range to meet diverse industrial load requirements.

Frequently Asked Questions

Q: What is the primary advantage of a clamping sleeve coupling over a keyed coupling?

Clamping sleeve couplings provide a 360° wrap-around grip that distributes stress evenly across the shaft, eliminating the need for keyways and reducing the risk of shaft stress concentrations.

Q: Can JK series couplings handle misalignment between shafts?

Because these are rigid couplings without elastic elements, their ability to compensate for radial or angular displacement is very limited. Strict alignment of the two shafts is required during installation.

Q: In which industries are clamping sleeve couplings most commonly used?

They are widely used in general equipment manufacturing for pumps, fans, conveyor belts, and agitators, especially in setups where space is limited and high torsional rigidity is needed.

Q: How do I choose between steel and aluminum alloy for my coupling?

Steel is recommended for heavy-duty applications requiring maximum torque (up to 15,000 Nm). Aluminum alloy is ideal for light to medium loads where weight reduction and corrosion resistance are priorities.

Q: Does the JK series require regular lubrication?

No, the clamping sleeve coupling is designed to be maintenance-free. There are no sliding parts or elastic inserts that require lubrication or periodic replacement.

Q: What happens if the bolts are not tightened to the correct torque?

Insufficient bolt tension can lead to slippage between the coupling and the shaft, resulting in torque loss or damage to the shaft surface. Always use high-strength bolts and follow specified torque settings.
