Product Description

Maximum Rigidity for Precision Motor Drive

 

The UNKW and CSKW Series are designed for high-performance transmission systems that demand exceptional torsional rigidity. Built from premium 42CrMo alloy steel, these cross-axis universal joints provide rapid response in both clockwise and counter-clockwise rotations, making them the ideal link for servo motors and factory automation (FA) systems.

 

[Why Choose UNKW/CSKW Series?]

  • High Torsional Rigidity: Engineered to minimize twist under load, ensuring accurate positioning and high transmission efficiency in motor-driven applications.

  • Premium 42CrMo Build: Professional heat treatment provides the perfect balance of strength and toughness, offering superior resistance to fatigue and impact.

  • H7 Grade Precision: Inner bores are machined to H7 tolerance for high concentricity, reducing vibration and ensuring a snug fit on the shaft.

  • Large Angle Compensation: Capable of operating within a 30° working angle, with an extreme limit of 45° per joint, compensating for both radial and angular deviations.

  • Low Noise Performance: Precision-ground components and tight clearances ensure smooth, quiet operation even at high speeds (up to 1800 RPM).
