K 81217 TN-Thrust cylindrical roller bearing-FGFA bearings

K 81217 TN Cylindrical roller and cage thrust assembly

Thrust cylindrical roller bearings are transmission components specifically engineered for heavy axial loads. Featuring a cylindrical roller configuration, they offer a large contact area and high load-carrying capacity, capable of withstanding unidirectional or bidirectional axial forces. These bearings find extensive application in heavy-duty scenarios such as metallurgical equipment, mining machinery, and marine transmission systems.
