Maximum Angular Flexibility: WXD Series Needle Bearing Universal Joints

The WXD Series Single and Double Universal Joint Couplings stand as the industry benchmark for high-torque power transmission across misaligned shafts. Manufactured in strict compliance with the national JB/T5901-1991 standard, these precision cross-type joints  are engineered to connect shafts where the spatial intersection angle is severe. Forged from premium 42CrMo alloy steel and integrated with high-load needle bearings, the WXD series combines high torsional rigidity with a low moment of inertia. Rated for an impressive peak speed capability up to 1,800 RPM and supporting a maximum torque rating up to 20.1 N·m, these components ensure smooth, low-noise rotational velocity transfer even under harsh multi-angle deflection profiles.

Core Product Advantages

• Premium 42CrMo Alloy Steel Construction: Forged from high-grade 42CrMo alloy steel to deliver exceptional mechanical strength, toughness, and fatigue resistance under repeating dynamic shock loads.

• Advanced Heat Treatment: Subjected to rigorous hardening and tempering protocols, drastically increasing surface anti-wear characteristics and ensuring the core survives high-load impacts.

• Massive $45^\circ$ Angular Compensation: Accommodates a large operational deflection angle up to $40^\circ$ for normal service loops and a maximum design limit up to $45^\circ$ per individual joint segment.

• H7 Precision Finished Bores: Every internal hub is CNC-machined to an absolute finished tolerance of H7, guaranteeing perfect concentricity, tight shaft mating, and zero rotational runout.

• High Torsional Stiffness & Low Noise: Outfitted with precision needle bearings that eliminate structural backlash, ensuring a tight mechanical fit and highly stable power delivery at 1,800 RPM.

• Versatile End-Hole Sizing Profiles: Standard stock bores can be customized into standard round holes, parallel keyways, hexagonal profiles, or square openings depending on your system blueprint.

• Comprehensive OBM/ODM/OEM Customization: Backed by Apexcoupling’s dedicated manufacturing facilities, we support direct custom brand engraving and non-standard length or hub configurations to fit any machinery chassis.
