Deep Groove Ball Bearings SKF 608 /C3

The SKF 608/C3 deep groove ball bearing, with dimensions of 8x22x7 mm, offers compact installation dimensions, increased radial clearance and precise running characteristics for demanding shaft mountings.

The SKF 608/C3 deep groove ball bearing is a single-row miniature roller bearing made from standard 100Cr6 bearing steel. With a bore of 8 mm, an outside diameter of 22 mm and a width of 7 mm, this open bearing primarily accommodates radial loads. As it does not feature integrated sealing washers, the unit starts up with low friction. A guided sheet steel cage maintains an even spacing between the rolling elements and supports continuous operation in clean lubrication environments.

What is the 608/C3 deep groove ball bearing suitable for?

This radial ball bearing is designed to support small rotating shafts in confined spaces. As the component is of open design, it is suitable for enclosed housing constructions in which lubricating oil or grease is supplied from the outside. The design covers a temperature range from -20 to +150 degrees. The absence of abrasive seals makes it ideal for applications where low rotational resistance and high speeds are required.

What do C3 bearing clearance and tolerance class P6/P5 mean?

The abbreviation C3 denotes a slightly increased radial bearing clearance compared with the standard version. This additional operating clearance compensates for thermal expansion when the bearing heats up or for tight fits on the shaft, without the bearing becoming stressed. In addition to the increased bearing clearance, this variant is characterised by enhanced manufacturing precision: dimensional accuracy complies with tolerance class P6, whilst running accuracy is manufactured to P5. These tight running tolerances reduce vibrations and promote smooth concentricity during operation.
