Federal-Mogul Bearings 5206-KZZE Deep Groove Ball Bearing

5206-KZZE is a double‑row, deep‑groove ball bearing from Federal‑Mogul Bearings (National brand) that uses shields on both sides (the ZZ suffix) to resist contamination and retain lubricant in radial‑load service. This shielded design suits automotive and light industrial equipment where reliable, low‑friction rotation is required and where external sealing is not practical. In distributor catalogs and aftermarket inventories, it is listed as NB5206KZZE or 5206KZZE under National Bearings and BCA lines, indicating its role as a general‑purpose, multi‑use bearing for drives, gearboxes, conveyors, and other rotary assemblies that demand solid radial support and compact form. The deep‑groove geometry supports smooth operation across a range of speeds while tolerating small axial displacements, making it a versatile choice for applications that experience both radial loads and mild misalignment. Because the bearing family is widely stocked, the 5206KZZE designation appears across automotive and industrial supply channels, often aligned with standard bore and outer‑ring sizes used in mid‑size equipment. When selecting a part, consult the specific NB5206KZZE documentation from the supplier to confirm bore, outer diameter, and width to ensure an exact fit for your housing and shaft.
