Product Description

In complex mechanical systems where power must be transmitted between non-collinear shafts over variable distances, a sophisticated solution is required. The double universal joint coupling, often configured as a telescopic Cardan shaft, is engineered specifically for this challenging task. Apexcoupling, a specialist supplier of universal joints and drive shafts, offers the robust WSP Series Telescopic Double Universal Joint Coupling. This assembly is designed to efficiently transmit torque while accommodating significant angular misalignment and axial movement, making it indispensable for dynamic industrial applications.

A double universal joint coupling consists of two universal joints connected by a telescoping intermediate shaft. This configuration allows the assembly to absorb and compensate for parallel offset, angular misalignment (typically up to 45° per joint section, for a maximum system angle as required), and changes in the distance between the driving and driven units. The telescopic feature provides a adjustable stroke, defined by Lmin and Lmax dimensions, which can be precisely calculated and customized to your specific installation requirements, offering unparalleled flexibility in machinery layout and compensating for equipment movement or settlement.

Our WSP Series double universal joint coupling is constructed from premium 42CrMo alloy steel, a material chosen for its superior strength, fatigue resistance, and durability compared to common S45C steel. This ensures reliable performance under high torque loads ranging from 25 to 6300 N.m. The coupling’s joints can be fitted with either needle roller bearings (recommended for high-speed applications over 800 RPM) or durable friction bearings for lower-speed, high-torque scenarios, ensuring optimal performance for your specific operating conditions. The finished hole tolerance of H7 guarantees a precise fit on the shaft, and we offer various bore types including keyway, square hole, and hexagon hole to suit your connection needs.

This versatile double universal joint coupling finds critical applications across Building Material Shops, Manufacturing Plants, Construction, Energy & Mining, and Food & Beverage processing. It is commonly used in rolling mills, conveyors, pumps, generators, and agricultural machinery where alignment is imperfect or variable. Apexcoupling supports full customization (OEM, ODM, OBM), allowing you to specify the exact length (L), stroke (X), outer diameter (22-150mm), surface treatment (blacking, nickel plating, Dacromet, etc.), and torque capacity. Every coupling undergoes stringent quality checks and is backed by our ISO9001 certification and a 1-year warranty.

Choosing the right double universal joint coupling is crucial for system reliability, safety, and longevity. The Apexcoupling WSP Series provides a robust, customizable, and high-performance solution that bridges gaps—both literal and mechanical—in your power transmission system. It represents a commitment to engineering excellence and operational durability.

For demanding applications that require power transmission across variable distances and angles, trust the engineered reliability of the Apexcoupling telescopic double universal joint coupling.
