Deep Groove Ball Bearings FAG 16008 -C3

The 16008 -C3 deep-groove ball bearing from FAG Wälzlager, measuring 40x68x9 mm, features a narrow design with increased bearing clearance for demanding radial loads.

The single-row deep-groove ball bearing 16008 -C3 primarily accommodates radial loads as well as moderate axial forces in both directions. Manufactured from standard rolling-element bearing steel 100Cr6, this FAG Wälzlager design combines dimensional stability with a compact footprint. Thanks to its narrow design, the component is particularly suitable for applications with limited axial installation space. A guided sheet steel cage maintains the spacing between the rolling elements and ensures smooth running characteristics within an operating temperature range of -20 to +150 degrees.

What is the 16008-C3 deep groove ball bearing suitable for in industrial applications?

Design engineers and maintenance personnel prefer to select this radial ball bearing for mounting locations with limited installation space, where wider bearings cannot be fitted. As it is an open design without sealing washers, the bearing can be integrated directly into enclosed housings with an existing lubrication circuit. The open design also facilitates targeted relubrication and reduces the friction torque compared with contact-sealed variants.

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

The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional clearance between the rolling elements and raceways compensates for thermal expansion caused by heating during continuous operation, without the balls becoming stressed. Similarly, the C3 clearance compensates for radial contraction when the inner ring is pressed onto the shaft with a tight interference fit. In terms of manufacturing tolerance, the model corresponds to the standard class P0/PN or ABEC 1.
