Product: HGR15 / HGR20 square linear guide rail with matching slider blocks Key benefits Precise, smooth linear motion: HGR square rails provide stable, low-friction guidance for accurate positioning and repeatable travel. Robust, long-lasting construction: Linear bearings and slider blocks are manufactured from high-quality bearing steel for improved wear resistance and durability in industrial use. Easy system compatibility: Designed for direct use with standard HGH and HGW slider block types for straightforward integration or replacement. Versatile sizing: Available in HGR15 and HGR20 sizes to match compact and medium-duty applications without changing system architecture. What’s included 2 × HGR linear rails (HGR15 or HGR20) 4 × slider blocks (HGH15CA / HGH20CA or flange type HGW15CC / HGW20CC) Note: Slider block models correspond to the rail size and mounting style required for your application. Function and performance highlights Function: Provides guided linear movement for stages, axes, and carriages in mechanical systems. Compatibility: Works with HGH15CA / HGH20CA carriage blocks and HGW15CC / HGW20CC flange blocks. Material: Slider blocks and rails use high-quality bearing steel for consistent rolling contact and extended service life. Performance: Engineered to maintain rigidity under load, reduce friction, and deliver repeatable motion for positioning and automation tasks. Practical applications CNC machines and milling equipment: Replace or upgrade X/Y axis guides to restore precision and reduce play. Automated assembly and pick-and-place systems: Ensure smooth, repeatable linear travel for production throughput and accuracy. Precision stages and inspection rigs: Provide controlled, low-friction motion for metrology, camera positioning, or laboratory automation. Why choose this set Direct compatibility with common HGH/HGW slider block families simplifies installation and spare-part planning. High-quality bearing steel components deliver dependable performance in demanding mechanical and industrial environments. Package contains the rail and multiple slider blocks needed to mount and operate a dual-rail linear axis immediately. Ordering tips Confirm the correct size (HGR15 or HGR20) and slider block model (HGH15CA / HGH20CA for carriage blocks, HGW15CC / HGW20CC for flange-style blocks) to match your existing hardware or design requirements.
