HIWIN RGH-CA/HA RG Roller Type Linear Guideway Square Block

HIWIN RGH-CA/HA RG Roller Type Linear Guideway Square Block

HIWIN RGH-CA/HA blocks belong to the RG Series Roller Type Linear Guideway, a high-rigidity roller-type linear guideway using rollers instead of balls in 45-degree line contact. Codes list each block model by size and load type; rail length, preload and accuracy are specified at order.

Key features

  • Rollers in line contact give very high rigidity and load capacity
  • Four rows of rollers in 45-degree contact carry equal load in four directions
  • Suited to machine tools and heavy-duty equipment
  • Non-interchangeable supply for high mounting accuracy
  • Top-mount (R) and bottom-mount (T) rail options
