Features

DURBAL heavy-duty rod ends in aluminium with integral spherical-plain bearing, series E, female thread, according to DIN ISO 12240-4 and DIN ISO 8139
Right hand thread: EFA_-60-501 and left hand thread: EFA_-60-502

  • Housing: high-strength aluminum, surface anodized silver, several colour variants available additionally on request
  • Race DURBAL-Glide: Polyamid-PTFE-fibreglass-Compound
  • Joint ball: stainless steel, hardened, ground, polished
  • Maintenance: maintenance-free
  • Tolerances: see on this page
  • Highlights: see on this page
  • Temperature range: -30° C to +60° C

Special characteristics:

  • Extreme low weight compared to other rod ends made of steel; for example EFA 12-60-501 ALU-type, weight: 0.036 kg; EF 12-60-501 stainless steel-type, weight: 0.086 kg
  • The aluminium rod ends are insulated, in consequence do not conduct current and therefore ideal for outdoor applications
  • 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 balls are made of stainless steel, hardened, ground, polished
  • All housings are made of high-strength aluminium with a very good corrosion resistance, an extremely hard and scratch-resistant surface that is standard anodized silver; several colour variants available additionally on request. Furthermore all of them show a high mechanical load capacity.
  • 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.

​​​Available as a complete linkages (system) solution or separately with hexagonal locking nuts. For shaft diameters from 6 mm to 25 mm.
