Product Description
CNC Machine Tool Precision Transmission Special Core Component: Linear Guide Rail and Slider with Precise Repeat Positioning

Linear guides and sliders are custom-designed for core CNC machine tool transmission applications, precisely adapting to critical components such as X/Y/Z axis feed systems, spindle box guidance, and precise table positioning. They are core components ensuring CNC machining accuracy and efficiency. Utilizing a four-row ball bearing load design, they possess exceptional high rigidity and four-directional equal load capacity, stably withstanding radial and overturning torques during cutting and preventing motion deviation.

A unique DF circular arc groove combination provides excellent self-aligning capability, precisely absorbing installation errors and achieving μm-level repeatability, ensuring dimensional consistency in the machining of complex parts. Made with selected high-strength alloy steel and an optimized lubrication structure, they are wear-resistant, durable, and operate quietly, suitable for the long-term continuous operation requirements of CNC machine tools. The sliders and guides are interchangeable, facilitating installation. Having passed stringent quality certifications, they provide reliable transmission support for CNC milling machines, machining centers, and other equipment.
