HIWIN QHW-CB/HB QH Quiet Heavy Load Linear Guideway Flange Block

HIWIN QHW-CB/HB QH Quiet Heavy Load Linear Guideway Flange Block

HIWIN QHW-CB/HB blocks belong to the QH Series Quiet Heavy Load Linear Guideway, a low-noise heavy-load linear guideway with SynchMotion ball-linking technology. Codes list each block model by size and load type; rail length, preload and accuracy are specified at order.

Key features

  • SynchMotion linkage separates the balls for low noise and smooth motion
  • Four rows of balls in gothic-arch contact for high load capacity
  • Dimensions interchangeable with the HG series
  • Improved lubricant retention for longer service intervals
  • Interchangeable and non-interchangeable versions
