The EGH25 EGH25CA Linear Guide Rail with Slider provides precise, smooth linear motion for demanding applications. Designed to work with EGH25 and EGH25CA slider systems, this unit combines a 400 mm rail with a travel range from 100 to 520 mm and includes one additional slider for replacement or extended use. Key benefits precision and repeatable positioning for accurate results in automated systems. Low friction and reduced wear due to precision ground rails and slider components. Stable, rigid motion suitable for 3D printers, CNC machines, laser engravers, and robotic gantries. Simple installation and maintenance, with an extra slider included for convenience. Key attributes Functionality: linear guide rail with slider for controlled linear motion Compatibility: designed for EGH25 and EGH25CA slider systems Size: rail length 400 mm; travel range 100 to 520 mm Material: material details are not specified in the listing Performance: intended for precision and smooth motion under typical machine operations Applications and use cases 3D printing: use as a precision axis guide for the print bed or gantry to improve layer alignment and print quality. CNC machines: serve as the X or Y axis guide in milling, routing, or engraving workflows to enhance positioning accuracy. Laser cutting/engraving: provide accurate gantry motion for consistent beam placement and cut quality. Package and components Includes 1 additional slider in the package for extended use or replacement alongside the builtin slider Note Material specifications are not provided in the listing; verify material details if that is important for your project. This description reflects the model and features as listed for EGH25 and EGH25CA linear guide rails with a 400 mm rail and a 100–520 mm travel range.
