HIWIN HGH-CA/HA HG Heavy Load Linear Guideway Square Block

HIWIN HGH-CA/HA HG Heavy Load Linear Guideway Square Block

HIWIN HGH-CA/HA blocks belong to the HG Series Heavy Load Linear Guideway, a heavy-load ball-type linear guideway with four rows of balls in circular-arc contact. Codes list each block model by size and load type; rail length, preload and accuracy are specified at order.

Key features

  • Four rows of steel balls in 45-degree circular-arc contact carry equal load in radial, reverse radial and lateral directions
  • Self-aligning design absorbs mounting errors for smooth travel
  • Interchangeable and non-interchangeable versions with identical dimensions
  • Retainer keeps balls in the block when it is removed from the rail
  • Dust protection options: end seal, bottom seal, double seal, scraper (ZZ, KK, DD), E2 self-lube, SE metal end cap
