Maintenance‑free plain bearings adopt advanced sliding materials such as ELGOGLIDE, ELGOTEX and metal‑polymer composite E40. These PTFE‑based materials deliver ultra‑low friction coefficients for spherical plain bearings, rod ends, bushes, washers and thrust plates, together with low wear and long service life. Requiring no oil or grease lubrication, they greatly reduce lubricant and maintenance costs and are environmentally friendly.
