Introduction
The HG Extended Slider is a high-performance extended slider specifically designed for precision motion control. Crafted from premium materials and precision-engineered processes, it ensures long-term stability and durability. Its elongated structure provides a wider travel range and enhanced load capacity, making it ideal for applications requiring high-precision linear motion such as automated equipment, robotic arms, and 3D printing. Whether in industrial applications or DIY projects, the HG Extended Slider delivers smooth, low-noise operation that significantly boosts work efficiency.
| Feature Aspect | Description & Advantage |
|---|---|
| Lengthened Structure Design | Compared to the standard block (HGH), the HGL block is significantly longer in length, typically by 30%–50%. A longer block means a wider distribution of ball contact points, resulting in more uniform force distribution. |
| More Mounting Bolt Holes | More mounting bolt holes (typically 4–6) are provided on the top and sides of the block, allowing more bolts to fix the load platform. This ensures a firmer connection and more effective torque transmission. |
| Ultra-High Rigidity | The lengthened structure combined with more mounting bolts gives the HGL block excellent resistance to overturning moments, with deformation resistance far exceeding that of standard blocks. This ensures system stability under heavy‑load conditions. |
| Higher Load Capacity | Due to an increased number of effective ball contact turns, both dynamic and static load ratings of the HGL block are significantly higher than those of the standard block in the same series. For example, the HGL25 achieves a dynamic load rating of 48.15 kN, approximately 40% higher than that of the HGH25. |
| Excellent Impact Resistance | The lengthened structure distributes impact loads, enabling the block to better withstand instantaneous shocks and vibrations. This makes it suitable for high dynamic load scenarios such as cutting and stamping. |
| High Precision Retention | Precision‑ground raceways and preload adjustment technology ensure stable running accuracy and a backlash‑free condition even under long‑term heavy‑load operation. |
| Comprehensive Sealing & Lubrication | Multiple sealing options (standard seals, double seals, scrapers, etc.) are available to effectively prevent dust and chips from entering the raceway. Optional self‑lubricating units extend maintenance intervals. |
| Corrosion Resistance Options | Martensitic stainless steel or surface coating treatments are available for humid, corrosive environments or cleanroom applications. |
| Good Interchangeability | HGL blocks of the same specification have good interchangeability with HGR rails, facilitating spare parts procurement and after‑sales maintenance. |
Application Scenarios
The HGL lengthened slider is particularly suitable for the following high-rigidity, high-load applications:
| Application Field | Specific Equipment | Selection Rationale |
|---|---|---|
| Large CNC Machine Tools | Gantry machining centers, vertical/horizontal machining centers, large CNC boring and milling machines | Heavy-duty cutting generates large overturning moments, requiring ultra-high rigidity sliders |
| Heavy-Duty Automation | Heavy-load truss robots, large material handling systems, press-fitting equipment | Large loads and strong impact demands high load capacity and impact resistance |
| Laser Cutting Equipment | Large-format laser cutting machines, tube cutting machines | Long-stroke heavy-load tables require resistance to bending deformation |
| Injection Molding Machines / Die-Casting Machines | Large clamping mechanisms, ejector mechanisms | High dynamic loads require sliders with excellent rigidity |
| Measurement & Inspection | Large coordinate measuring machines (CMM), aircraft component inspection platforms | Ultra-high precision requirements demand long-term motion accuracy retention |
| Aerospace & Heavy Industry | Aircraft component assembly platforms, rocket shell processing equipment | Heavy mass loads with extreme system rigidity requirements |
