Deep Groove Ball Bearings FAG 6209 -Z

The FAG 6209-Z deep-groove ball bearing, measuring 45 x 85 x 19 mm and featuring a single-sided sheet metal cover, provides protection against external dirt particles.

The 6209-Z deep groove ball bearing is a single-row radial ball bearing made from standard rolling bearing steel (100Cr6) with a bore of 45 mm, an outer diameter of 85 mm and a width of 19 mm. The design primarily accommodates radial loads and guides shafts within the housing. Thanks to its manufacture to tolerance class P0 or ABEC 1, this rolling bearing fits precisely into industrial designs.

What loads and conditions can the 6209-Z deep groove ball bearing handle?

In general mechanical engineering, this design is used to support rotating components. As deep-groove ball bearings can accommodate not only high radial forces but also moderate axial forces in both directions, they are suitable for a wide range of mechanical drives. The guided sheet steel cage maintains an even spacing between the rolling elements and ensures smooth running at operating temperatures ranging from –30 to +120 degrees Celsius.

What are the characteristics of the single-sided Z-end plate?

The ‘-Z’ designation refers to a non-contact gap seal made of profiled sheet metal on one side of the bearing. This design protects the internal components from coarse particles, whilst the opposite open side allows for lubricant exchange via a housing system. Furthermore, the non-contact cover ring does not generate any additional friction on the inner ring. Before installation, it should be checked whether the standard radial bearing clearance is suitable for the operating temperatures and shaft fits.
