Industrial automation equipment is crucial for improving production efficiency and stability. Automated machinery, robotic systems, packaging lines, and testing equipment require high-precision, long-life, and low-maintenance rotating components. Slewing bearings, with high load capacity, smooth rotation, and compact structure, have become indispensable in industrial automation.
Slewing bearings are specialized bearings capable of supporting axial loads, radial loads, and overturning moments simultaneously. They enable large-diameter, low-speed, high-load rotation and are widely used in equipment requiring precise positioning and continuous rotation. In industrial automation, slewing bearings bridge control systems and actuators, ensuring precision, stability, and responsiveness under high-speed and high-frequency dynamic operation.
