HGR15 / HGR20 Square Linear Guide Rail System — 2 rails + 4 slider blocks (HGH-CA or HGW-CC) What this product does Provides precise, low-friction linear guidance for positioning and motion systems. Designed for smooth, repeatable travel and reliable load support in industrial and equipment applications. Key benefits — why you need it Precision and stability: Precision-ground slider block models (HGH15CA / HGH20CA or flange HGW15CC / HGW20CC) deliver consistent positioning and reduced play. High durability: Rails and sliders are made from high-quality bearing steel for wear resistance and long service life. Balanced load support: Package includes 4 slider blocks to distribute loads evenly and increase rigidity for gantry or long-rail setups. Easy integration: Square-profile HGR rails are compact and support secure mounting and alignment for various machine designs. Reduced maintenance: Robust material and design minimize premature wear and help maintain performance under continuous use. Specifications and compatibility Rail types: HGR15 and HGR20 (select the appropriate size for your application). Slider block models: HGH15CA, HGH20CA (standard blocks) and HGW15CC, HGW20CC (flange-type blocks). Package contents: 2 x HGR linear rails (matching selected size) + 4 x slider blocks (matching selected size and block style). Material: Linear bearings and rails manufactured from high-quality bearing steel. Function: Linear guidance for accurate straight-line motion and load carrying. Typical applications (practical use scenarios) CNC routers and milling machines: Use the rails and multiple slider blocks to support gantry movement and maintain rigidity under cutting loads. Automated assembly or pick-and-place systems: Provide precise linear travel for repeatable part handling and positioning. Inspection equipment and measurement stages: Deliver smooth, low-vibration motion for accurate sensor or camera positioning. Installation and selection notes Match rail size and slider model: choose HGR15 with HGH15CA or HGW15CC, or HGR20 with HGH20CA or HGW20CC to ensure correct fit and performance. The package includes 4 slider blocks to allow configurations with two sliders per rail or other balanced mounting arrangements depending on your design. For best results, follow manufacturer torque and alignment recommendations during installation and use appropriate lubrication intervals. What you get A complete basic linear motion set: 2 HGR rails + 4 compatible slider blocks, made from high-quality bearing steel for reliable, long-term linear guidance.
