Product Description
JB/T5901-1991 Standard: WX/WXD Precision Mini Cross Universal Joints
The WX (Single) and WXD (Double) Series are ultra-compact cross-axis universal joints engineered for precise mechanical linkages in tight spatial profiles. Adhering strictly to the JB/T5901-1991 standard, these couplings transfer nominal torques ranging from 11.2 to 1120 N.m. Forged from premium 40Cr/35CrMo alloy steel and refined through full CNC machining and professional heat treatment, the WX/WXD series is the premier choice for multi-axis tapping machines, drilling equipment, and factory automation lines.
Core Product Advantages
Premium Material & Heat Treatment: Built from high-grade 40Cr or 35CrMo alloy steel, providing exceptional fatigue life and high-impact wear resistance under continuous operating cycles.
45° High Angular Displacement: Accommodates an operational angular misalignment of up to 45° per joint, allowing the angle between the two shafts to adapt dynamically during operation.
H7 Finished Bore Precision: Bores are kept inside a strict H7 tolerance window, ensuring perfect concentricity, strong locking power, and low vibration runout.
Flexible Machining Profiles: Standard stock features round bores, with full support for custom keyways, hexagonal bores, square holes, and custom pin-retaining configurations.
Anti-Rust Surface Excellence: Finished with premium polishing or chemical blackening anti-rust treatments to retain surface integrity and prevent oxidation in oily workshop environments.
100% CNC Monitored Quality: Every unit goes through rigorous post-production inspection, guaranteeing structural uniformity and stable high-torque transmission.
