Details

Special characteristics:

  • Extreme low weight compared to other rod ends made of steel; for example BEFA 12-60-501 ALU-type, weight: 0.056 kg; BEF 12-60-501 stainless steel-type, weight: 0.109 kg
  • The aluminium rod ends are insulated, in consequence do not conduct current and therefore ideal for outdoor applications 
  • VORBAL-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 and approximately have the same load ratings as the steel items of a competitor (e.g. size 12: static 23 kN; VORBAL aluminium – rod ends BEFA 12-60-501: static 22.1 kN). Compared to stainless steel variant of size 12: static 15 kN; VORBAL has significantly got higher values at 22.1 kN;
  • No clearance: radial clearance 0 – 10 µm;
  • Suitable for use with impact loads;
  • For use with small swivelling movements and at low speeds.
