Flat Air Bearings – HRA series

INTENDED USE AND APPLICATIONS

The HRA series (High Resistance Aluminium) is ideally applied to heavy weight or inertia of motion systems, where it is necessary and sufficient to minimise the friction forces and therefore the forces applied for motion and transfer operations. They are however also perfectly suitable for use in precision applications, specifically for the HPR and HPC series.

Their use is recommended in the following conditions:
  • High static and dynamic forces (also over a ton)
  • Elevated dimensional and geometrical errors on sliding guides
  • Solid, liquid or gaseous pollutants (dust and scrap from machining, lubricating oils and grease, process gas)
  • High temperatures

FEATURES

They are manufactured using aluminium with an anodised surface treatment and equipped with a dense air distribution network on the work surface. These features make the pad particularly efficient, even on particularly irregular surfaces with dimensions and roughness over 1.6 micrometres.

The HRA series air bearings are available:

  • both in a rectangular (HRA-#) and circular (HRA-C) version
  • with stationary assembly, with adjustable pivoting assembly (requiring the P-KIT ), and with a detachment or detachment-proof capacity.
  • with a aerostatic surface coated or uncoated in an anti-friction material (to resist overloading or the temporary absence of air in unexpected operating conditions)
  • without a built-in pre-loading system, with magnetic pre-loading or with vacuum chamber preloading
  • in a special version, for high lift forces (over a ton)

All HRA-# (rectangular) series air bearings can have a horizontal dust scraping kit assembled on the head (R-KIT).
