GR/C5
Description
GR/C5 is a double-acting scraper energised by an O-Ring that prevents the entry of mud or other contaminants, optimising service life.
Ideal for use in mobile hydraulic systems in harsh 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.
