GR/CG
Description
GR/CG is a double-acting scraper energised by an O-Ring that prevents the entry of mud or other contaminants, optimising service life. The extended lip prevents dirt from accumulating in front of the scraper. It can be used for medium- and heavy-duty operations. Ideal for use in mobile hydraulic systems in heavy-duty conditions. It can be used as a secondary seal in combination with the GCR (single-acting seal).
  • Good scraping results even with hard-to-remove dirt;
  • Good hold of residual oil film on the piston rod;
  • Excellent sliding properties;
  • No stick-slip;
  • High resistance to hydraulic flows;
  • Scraper for heavy-duty operation;
  • Can compensate for bending of the rod and piston.
