Details
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
- 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.
- 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.
