  • All rod end housings are made of forged steel, tempered, extremly high loads resistant and protected against corrosion by galvanisation.
  • No clearance: radial clearance 0 – 10 µm;
  • Suitable for use with impact loads;
  • For use with small swivelling movements and at low speeds.
  • Connection dimensions in accordance with DIN ISO 8139 for pneumatic cylinders.
