iglidur® plain bearings are made of tribologically (for friction and wear) optimised high-performance plastics specifically designed by igus®. They contain solid lubricants, that after the start-up phase are always located at the contact surface to the shaft and in addition are partially released when the counter partner is moved. Thus, the solid lubricants are also deposited on the shaft surface via micro-abrasion, lubricate the plain bearing and make it maintenance-free.
Needle bearings require a continuous lubrication If the lubricant fails, material damage occurs leading to the so-called seizure. Many rolling bearing damages are caused by a lack of or incorrect lubrication.
