WX Universal Joint Coupling: The High-Strength Solution for Angular Misalignment

The WX Universal Joint Coupling, alongside its single-joint counterpart the WXD type, stands as a pivotal component in precision mechanical power transmission systems. Manufactured in strict compliance with the JB/T5901-1991 standard, this small, robust universal joint coupling is engineered to solve the critical challenge of connecting two shafts with significant angular offset. At Apex Coupling, we produce the WX Universal Joint Coupling using premium materials and exacting tolerances, ensuring unmatched durability and performance in demanding applications. This small cross shaft coupling is the reliable link where traditional couplings fail.

Unmatched Construction & Technical Superiority

What sets our WX Universal Joint Coupling apart is its exceptional build quality, designed for longevity under stress.

• High-Strength Alloy Steel Core: We utilize 42CrMo alloy steel for critical components, undergoing advanced heat treatment to achieve a surface hardness of HRC 56-58. This ensures superior wear resistance, high fatigue strength, and the ability to handle shock loads, making it far more durable than standard carbon steel versions.

• Precision Engineering for Reliable Fit: Every WX Universal Joint Coupling features an H7 precision finished bore, guaranteeing minimal clearance and optimal grip on the shaft. This high tolerance reduces vibration, lowers noise, and enhances overall transmission accuracy and lifespan.

• Optimized Design for Maximum Performance: The compact, yet powerful design of the WX series coupling allows for a maximum working angle of 30°-45° per joint section. The double-joint WX type and single-joint WXD type provide flexibility in system design to accommodate various spatial and alignment constraints.

Technical Specifications & Model Selection

The WX Universal Joint Coupling series offers a nominal torque range from 11.2 N.m to 1120 N.m (with custom higher torque available). Key selection parameters include shaft diameter (dmax), outer diameter (D), and the critical length dimensions (L, L1, L2, L3). Our standard models, from WX1/WXD1 to WX6/WXD6, are detailed in the table below, providing clear data for engineers to specify the correct component.

Note: Comprehensive dimensions (L, L1, L2, L3, L4) and inertia values are available in our full technical datasheet.

Ideal Applications and Customization Capabilities

The versatility of the WX Universal Joint Coupling makes it indispensable across numerous industries. It is extensively used in packaging machinery, woodworking equipment, multi-spindle drills, textile machines, and special metallurgical drives. Whether you require the standard double-cross WX type for synchronous rotation or the single-cross WXD type for specific configurations, we provide the solution.

As a factory-direct supplier, Apex Coupling offers full customization. Beyond standard H7 bores with keyways, we can provide hexagonal or square holes, different fixing methods, and special materials like stainless steel 304/316. Custom surface treatments, including black oxide, chrome plating, nickel plating, or sandblasting, are also available.

Choose Apex Coupling for Your Power Transmission Needs

In summary, the WX Universal Joint Coupling is more than just a connector; it’s a high-precision, high-strength engineered component built to endure. When you need a coupling that offers large angular compensation, minimal backlash, and exceptional durability, the WX series from Apex Coupling is the definitive choice.
