HGR15 / HGR20 Square Linear Guide Rail Package — precise, durable linear motion Key benefits Smooth, low-friction linear motion for accurate positioning and repeatable travel. High rigidity and long service life thanks to components made from high-quality bearing steel. Ready-to-install kit: includes rails and matching slider blocks for fast integration into machines and prototypes. Versatile compatibility: choose the appropriate slider block type (HGH-CA or flange HGW-CC) to match your mounting and load requirements. What’s included 2 x HGR linear guide rails (HGR15 or HGR20) 4 x matching slider blocks: HGH15CA / HGH20CA or Flange HGW15CC / HGW20CC (models correspond to selected rail size) Features and specifications Function: precision linear guidance for smooth, controlled motion and support of moving loads. Compatibility: HGR15 pairs with HGH15CA or HGW15CC sliders; HGR20 pairs with HGH20CA or HGW20CC sliders. Material: slider blocks and rails manufactured from high-quality bearing steel for wear resistance and consistent performance. Design: square-profile guide rails provide stable support and simplify alignment and mounting in multi-axis systems. Why this product solves problems Eliminates wobble and inconsistent motion caused by inferior rails, improving machining quality and repeatability. Reduces downtime: robust steel construction resists wear and extends maintenance intervals. Simplifies upgrades and repairs: standardized rail and slider models allow easy replacement and interoperability. Typical applications CNC routers, milling machines and gantry systems — for accurate axis movement and consistent surface finishes. Automation equipment and pick-and-place systems — for reliable repeatable positioning under continuous cycles. 3D printers, laser cutters and inspection stages — for smooth gantry travel and precise layer or scan alignment. Installation and maintenance tips Ensure mounting surfaces are flat and parallel for best accuracy and load distribution. Use the slider block type (HGH-CA or flange HGW-CC) that matches your mounting needs — flange blocks simplify side mounting, standard blocks suit top-mounted carriage designs. Periodically inspect and apply appropriate lubrication to maintain smooth operation and extend service life. Trustworthy choice Uses standard HGR / HGH / HGW model families for broad compatibility with existing systems and replacements. Straightforward kit content and robust materials ensure dependable performance in industrial and hobbyist applications.
