Product Description
The UNCA and UNCW Series are engineered for heavy-duty industrial applications requiring high torque and precision. Built from premium 42CrMo alloy steel, these universal joints provide a robust connection for factory automation (FA) systems, ensuring rapid response in both clockwise and counter-clockwise rotations.
Why Choose UNCA/UNCW Series?
Engineered for High Torque: Specifically designed for mechanical transmissions that face frequent impact and heavy loads.
Premium 42CrMo Construction: The use of high-grade alloy steel combined with professional heat treatment ensures maximum fatigue resistance and long-term durability.
H7 Precision Boring: Each joint is machined to H7 tolerance for superior concentricity, reducing vibration and mechanical wear.
Flexible Angular Support: Reliable operation within 30° working angles, with a maximum limit of 45° per joint, allowing for significant installation flexibility.
Versatile Configurations: Choose from Single-section (UNCA) or Double-section (UNCW), featuring pin-and-bushing or keyway designs.
