Telescopic Universal Joint Coupling: The Adaptive Solution for Variable-Distance Power Transmission

In dynamic mechanical systems where the distance between driving and driven shafts is not fixed, a standard rigid coupling creates stress and failure. The telescopic universal joint coupling is the engineered answer to this challenge, providing both angular flexibility and axial adjustability. At Apex Coupling, our WSP type retractable small cross shaft universal coupling exemplifies this dual functionality, crafted from high-strength 42CrMo alloy steel to deliver reliable, maintenance-free performance in applications ranging from printing presses to construction machinery.

Engineered for Flexibility, Durability, and Precision

Our telescopic universal joint coupling is designed to be the most adaptable link in your power transmission system, combining the benefits of a universal joint with axial adjustability.

• Adaptive Telescopic Design: The core feature of this telescopic universal joint coupling is its ability to extend and retract. This allows it to compensate for changes in the distance between connected equipment, absorbing axial movement, thermal expansion, and installation variances without imposing damaging forces on bearings or shafts. The stroke (X) and installation length (L) can be precisely calculated to meet specific spatial requirements.

• High-Angle Compensation & Robust Construction: Each joint section can accommodate a maximum rotation angle of 45°, providing exceptional flexibility to handle significant parallel and angular misalignment. The coupling body is manufactured from durable 42CrMo, a material chosen for its superior toughness, wear resistance, and ability to handle high nominal torque (from 25 to 6300 N.m). Critical components undergo a protective blacking surface treatment for enhanced corrosion resistance.

• Precision Fit for Reliable Connection: We ensure a perfect fit with an H7 tolerance finished bore, minimizing backlash and vibration. Customers can specify the bore type to match their application, choosing from a keyway, square hole, or hexagon hole. This level of precision ensures efficient power transmission and extends the service life of both the telescopic coupling and the connected machinery.

Technical Specifications and Customization Options

The WSP telescopic universal joint coupling is built to meet diverse engineering needs with a focus on quality and customization.

• Key Dimensions: Standard offerings include a 10mm bore diameter and a 400mm length, with outer diameters ranging from 22mm to 150mm. The minimum and maximum lengths (Lmin/Lmax) are fully customizable according to customer requests.

• Quality Assurance: Every coupling is produced under ISO9001 certified processes and backed by a 1-year warranty, ensuring you receive a component built to last.

• Full Custom Support: As a factory-direct supplier, we offer comprehensive OEM, ODM, and OBM services. Whether you need a specific stroke length, a unique bore configuration, or a different surface finish, our engineering team can tailor this telescopic universal joint coupling to your exact specifications.

Ideal Applications for Versatile Power Transmission

The unique combination of angular and axial flexibility makes this telescopic universal joint coupling indispensable in numerous industries:

• Printing & Packaging Machinery: Where printing cylinders or rollers may need positional adjustment.

• Construction & Energy: In equipment where the distance between the engine or motor and the implement may vary during operation.

• Machine Tools & Manufacturing: For connecting spindles or drives in systems with adjustable beds or slides.

• General Industrial Machinery: Any application involving variable-distance shaft connections that also experience misalignment.
