Features
DURBAL heavy-duty rod ends in aluminium with integral spherical-plain bearing, series K, female thread, according to DIN ISO 12240-4 and DIN ISO 8139
Right hand thread: BEFA_-60-501 and left hand thread: BEFA_-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 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
- 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 and approximately have the same load ratings as the steel items of a competitor (e.g. size 12: static 23 kN; DURBAL aluminium – rod ends BEFA 12-60-501: static 22.1 kN). Compared to stainless steel variant of size 12: static 15 kN; DURBAL 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.
Available as a complete linkages (system) solution or separately with threaded bolts and hexagonal locking nuts. For shaft diameters from 6 mm to 25 mm.
