HGR + HGH Slider Series – Square Type Heavy-Duty Linear Guideway

The HGH series is our flagship heavy-duty linear guideway product, paired with HGR series guide rails. It follows the widely copied HGH square-block footprint family; mounting dimensions carry over between makers, but verify block length and height per size. Suitable for CNC machine tools, machining centers, automation equipment, and other industrial applications requiring high rigidity and high load capacity. Available in HGH-CA (standard) and HGH-HA (extended) slider types.

Key Features

  • Assembly Replacement – Direct replacement of existing same-series assemblies
  • Heavy-Duty Design – High load rating, engineered specifically for heavy-duty applications
  • Extended Type (HA) – Longer slider body delivers significantly higher dynamic load rating and rigidity than CA type
  • Hardened Surface – Guide rails undergo surface hardening treatment for excellent wear resistance and long service life
  • High Positioning Accuracy – Precision machining processes meet demanding displacement accuracy requirements for industrial equipment

Custom Manufacturing Available

Standard ball screws and linear guides don't always fit your design. Here's what RFU MOTION can customize based on your drawings:

  • Shaft end machining — machined precisely to your drawing
  • Screw length — cut to your exact requirement
  • Preload — light, medium, heavy, or custom value
  • Nut type — standard flange, special shape, or non-standard mounting interface
  • Rail length — continuous cutting with end finishing (chamfer or grinding)
  • Mounting holes — special thread sizes, hole spacing, or countersunk dimensions

Send us your drawing or specs — we'll deliver exactly what you need.

📦 MOQ: 1 piece / 1 set
