Product: HGR15 / HGR20 square linear guide rails with matching slider blocks Why this product helps you Precise, repeatable linear motion: engineered for smooth, accurate guidance where controlled straight-line movement is required. Durable, maintenance-friendly construction: hardened bearing steel bearing surfaces provide long service life and consistent performance under repeated use. Ready-to-install kit: includes rails and slider blocks so you can replace, upgrade, or build a linear axis quickly without sourcing separate components. Key features and specifications Rail models: HGR15 and HGR20 square linear guide rails (compatible with standard HGR-series systems). Slider block models: HGH15CA / HGH20CA (standard carriage) and Flange HGW15CC / HGW20CC (flange carriage). Package contents: 2 x HGR linear rails + 4 x slider blocks (HGH-CA / HGW-CC). Material: linear bearings and contact surfaces manufactured from high-quality bearing steel for hardness and wear resistance. Function: provides constrained, low-friction linear guidance for loads moving along the rail. What makes it stand out Matched components: rails and slider blocks are specified to work together for consistent fit and preload options common to HGR systems. Robust material choice: bearing steel construction improves durability compared with untreated steels and helps preserve dimensional accuracy over time. Versatile carriage options: choose standard HGH-CA blocks for compact carriage or HGW-CC flange blocks where flange mounting is needed. Typical applications CNC machines and router tables requiring accurate linear axes for axes X/Y/Z. Automated assembly and pick-and-place equipment where predictable, low-friction travel is critical. Linear stages and test rigs in labs or small production setups that need reliable motion components. Ordering/compatibility notes Confirm whether your system uses HGR15 or HGR20 rails and select matching slider block models (HGH15CA/HGH20CA or HGW15CC/HGW20CC) as required. Package includes two rails and four slider blocks to support multi-carriage axes or dual-rail assemblies. Reliable, industrial-grade linear guidance ready for integration into standard HGR-series systems.
