Deep Groove Ball Bearings FAG 6009 -2Z-C3

The FAG 6009 -2Z-C3 deep-groove ball bearing, with a 45 mm bore, non-contact end shields and C3 clearance, offers stable running at high speeds.

The single-row deep groove ball bearing 6009 -2Z-C3 primarily accommodates radial forces as well as moderate axial loads in both directions. Manufactured from standard rolling bearing steel 100Cr6, this bearing is characterised by its dimensional stability and load-carrying capacity. This version has an inner diameter of 45 mm, an outer diameter of 75 mm and a width of 16 mm. A sheet steel cage guides the rolling elements in the raceways. The cylindrical outer ring has no flange or groove, allowing for flush mounting in suitable housing bores.

In which operating environments is the 6009-2Z-C3 deep-groove ball bearing used?

Designs requiring non-contact sealing and increased radial clearance constitute the typical field of application. The sheet metal cover plates on both sides protect the bearing’s interior from coarse dirt particles without causing additional friction or heat. The bearing is suitable for rotating shafts with high rotational speeds or those subject to operational heating. Thanks to its permissible temperature range of -30 to +120 degrees, the rolling bearing operates reliably even under fluctuating thermal conditions.

What are the advantages of the C3 bearing clearance in this bearing?

The C3 designation indicates a slightly increased radial clearance compared with standard clearance. This increased internal clearance serves to compensate for thermal expansion at operating temperature when the shaft and inner ring heat up. In addition, the C3 clearance compensates for radial constrictions that may arise from tight fits when the inner ring is fitted. With tolerance class P0 (ABEC 1), the bearing meets all standard industrial requirements for concentricity and dimensional accuracy when correctly installed.
