Industrial bearings reduce frictional forces between two moving parts by giving a surface something to roll on rather than slide over– they’re crucial for motion applications.
Idealno, you want to get the most life out of your bearings, but there are several reasons bearings fail. What are some of those reasons?
Not Enough or Too Much Lubrication
Most of the time, bearings fail because they’re not properly lubricated. There’s either not enough lubricant, the wrong lubricant, or excessive temperatures have degraded the lubricant. 8 times out of 10, bearings fail due to lubrication issues, so that’s the first thing to check when investigating when/why bearings fail.
Ležajevi se također mogu pokvariti kada strane tvari poput prljavštine ili čeličnih strugotina dospiju u maziva za ležajeve ili otopine za čišćenje. Lubrikant je možda potrebno filtrirati. Radna područja možda će biti potrebno očistiti.
Problemi s montažom
Što je s montažom? Ležajeve treba montirati pritiskom na rotirajući prsten. Ponekad prstenovi popucaju, udubiti ili istrošiti. Provjerite montažu kako biste vidjeli jesu li vaši ležajevi pravilno ili nepravilno montirani.
Ponekad stvari ne uspiju, uključujući ramena osovine, razmaknice ili stezne matice. Labavi spojevi mogu uzrokovati neusklađenost, što dovodi do pregrijavanja i kvara separatora.
Razna pitanja
Ako vidite linearne tragove trošenja u aksijalnom smjeru na koraku kotrljajućeg elementa, moglo bi postojati lažno slanjenje.
Ako primijetite crvene ili smeđe mrlje na kotrljajućim elementima, trkaće staze, itd., vlage, acid or grease could cause corrosion, and this corrosion is abrasive to the surfaces of ball and roller bea63rings.
Electrical damage could be the cause of bad bearings. Također, fatigue due to overloading can cause bearings to not function properly when there’s an excessive preload and/or tight inner-ring fits. Excessive loads and/or overheating can also cause failure.
