Product: HGR15 / HGR20 square linear guide rail with matching slider blocks What this product does Provides precise, low-friction linear motion for machine axes, stages, and gantries. Square-profile HGR rails guide slider blocks (carriages) to deliver stable, repeatable travel under load. Linear bearings are manufactured from high-quality bearing steel for wear resistance and long service life. Package contents 2 × HGR linear rails (models HGR15 or HGR20) 4 × slider blocks (HGH15CA / HGH20CA or flanged HGW15CC / HGW20CC, matching the rail size) Key benefits — why you need it Precision movement: Square guide geometry and matched slider blocks minimize wobble and maintain alignment for accurate positioning. Durable performance: Bearings made from high-quality bearing steel resist wear and give consistent performance over extended use. Smooth, low-friction operation: Reduces motor load and improves control stability for motion systems. Easy integration: Standard HGR rail form factor and corresponding HGH/HGW carriages fit common mounting setups and replacement needs. Important attributes Function: Linear guidance for translation motion in industrial and precision equipment. Compatibility: HGR15 with HGH15CA / HGW15CC; HGR20 with HGH20CA / HGW20CC (slider blocks correspond to the rail size). Size options: Available in HGR15 and HGR20 profiles to match load and space requirements. Material: Linear bearings and carriage components use high-quality bearing steel for durability and consistent rolling contact. Performance: Designed for stable, repeatable travel with low friction and reliable load carrying for typical machine motion tasks. Practical applications (use scenarios) CNC routers and laser cutters: Use the HGR rail and HGH/HGW carriages for X/Y gantry axes to keep the toolhead stable and precisely positioned. Pick-and-place and automation: Implement as linear axes in production machines where repeatable, low-friction motion reduces cycle time and improves accuracy. Linear stages and laboratory instruments: Provide smooth, controlled translation for inspection equipment, test rigs, or positioning tables. Installation and selection notes Choose the rail size (HGR15 or HGR20) and matching carriage model (HGH15CA / HGH20CA or HGW15CC / HGW20CC) based on required load capacity, rigidity, and available mounting space. Package includes two rails and four slider blocks for building dual-rail linear axes or multi-carriage systems. What you can expect Stable linear guidance suitable for industrial automation and precision machinery. Long service life from bearing-steel bearings when installed and maintained according to application requirements. Compatibility with standard HGR/HGH/HGW form factors for replacements and upgrades.
