Product Description

Precision Machine Tool Linkage: WX & WXD Small Cross-Shaft Universal Joints

The WX (Single) and WXD (Double) Series Small Cross-Shaft Universal Couplings serve as foundational power transmission components within advanced machine tool assemblies and hand socket steering mechanisms. Forged from high-grade 42CrMo alloy steel, these compact yokes are engineered to connect two intersecting shafts sharing a spatial plane where angular misalignments are exceptionally severe. Fully rated to manage nominal transmission torques spanning from 11.2 N·m to 1120 N·m, the WX/WXD family maintains excellent rotational tracking and low backlash under dynamic working configurations.

Core Product Advantages

High-Grade 42CrMo Steel Core: Forged from structural 42CrMo alloy steel to ensure maximum yield strength, shock resistance, and long-term fatigue durability under harsh industrial loading.
Exceptional $45^\circ$ Angular Deflection: Expertly accommodates large angular working offsets up to $45^\circ$ per single section, allowing the transmission path to adjust dynamically during operation.
H7 Precision Finished Bores: Standard inner holes are ground to strict H7 tolerances across a stock diameter spectrum of 10mm to 42mm, guaranteeing high concentricity and vibration-free runtime.
Flexible Drive Geometry Customization: Finished attachment holes can be customized with parallel keyways, square sockets, or hexagonal profiles to fit hand tools or automated machine spindles.
Polished or Blackened Options: Available with a high-shine polished steel finish or an anti-corrosive chemical black oxide treatment to meet specific wear and aesthetic requirements.
Compact Outer Diameter Profiles: Space-saving footprint with outer diameter scales ranging from 16mm to 75mm, allowing easy integration into tight equipment enclosures.
Direct Manufacturer OEM/ODM Backing: Supported by Apexcoupling’s dedicated manufacturing facilities, we deliver scalable custom non-standard lengths and specialized shapes directly from the factory floor.
