Linear guides are precision components used in automation and machinery to facilitate smooth and accurate linear motion. They are essential in applications requiring high rigidity, low friction, and long-term durability. Common types include ball bearing guides, roller guides, and crossed roller guides, which cater to different load capacities and precision requirements. Key features often include corrosion resistance, self-lubrication, and modular designs for easy integration. Typical products in this category include linear rails, linear stages, guide blocks, and recirculating ball bearings. These components are widely used in CNC machines, 3D printers, robotic arms, and other automated systems.
