Origin: Najico Universal Joint, Japan

Najico offers a comprehensive range of universal joints, from compact Type A models for general equipment to heavy-duty Type S designed for large-scale machinery such as steel rolling mills.

As a universal drive coupling (cross-type joint), it is specially engineered to deliver powerful and stable torque transmission between two shafts that may be non-collinear or significantly misaligned (typically up to 15–25 degrees).

1. Key Features: 

• High Angular Compensation: Efficient power transmission even with significant shaft misalignment, ideal for complex operating conditions.
• Optimized Structure: Compact and robust design with integrated yoke, enhancing reliability and heavy-load durability.
• High Load Capacity: Capable of transmitting greater torque compared to couplings of similar diameter—perfect for machinery with limited rotation space.
• High Transmission Efficiency: Achieves efficiency from 98% to 99.8%, contributing to energy savings.
• Smooth & Stable Operation: Low noise, minimal vibration, easy installation and maintenance.

2. Main Applications:

The SWC drive shaft is a critical power transmission component widely used in heavy industries and machinery requiring high and stable power transfer, including:

• Construction Machinery: Excavators, bulldozers, heavy-duty trucks, and off-road vehicles.
• Metallurgy Industry: Steel rolling mills and steel production lines.
• Other Industrial Sectors: Cranes, mining machinery, oil & gas equipment, shipbuilding, paper mills, and other heavy-duty industrial drive systems.
