Special characteristics:

  • DURBAL-Glide (race) made of polyamide-PTFE-glass fibre compound, maintenance-free, encapsulates penetrating foreign particles. This fact and the greater overlay thickness compared to other sliding materials assure a longer durability.
  • Joint ball made of ball bearing steel, hardened, ground, polished and hard chromium plated, ensures a reliable corrosion protection.
  • 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.
  • Free from non-ferrous metals.

​​​Available as a complete linkages (system) solution or separately with hexagonal locking nuts. For shaft diameters from 1/4″ to 1/1″.
