Linear ball bearing

  • small outer dimensions and highly compact construction
  • low-cost linear bushing for general requirements
  • high dynamic load rating and long service life due to hardened segmental load-bearing plates with ball conformity in the running track
  • simple mounting: just press on – no additional retention needed
  • many pockets acting as lubricant reservoirs for extended lubrication intervals or lubrication for life
  • pockets collect any dirt that may have worked its way in to prevent the linear bushing from jamming
