Deep Groove Ball Bearings SKF 6408 /C3

The 6408/C3 deep-groove ball bearing from SKF Rolling Bearings, measuring 40x110x27 mm, offers increased bearing clearance for industrial applications subject to thermal stress.

The single-row deep groove ball bearing 6408 /C3 is primarily designed to accommodate radial loads as well as moderate axial loads in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel, this bearing is characterised by dimensional stability within a temperature range of -20 to +150 degrees. The integrated sheet steel cage guides the rolling elements precisely at medium to high speeds. As an open design without sealing washers, the construction allows for flexible lubrication via oil or grease circuits in mechanical engineering.

What is the 6408 /C3 deep groove ball bearing suitable for in operation?

Users prefer to use this bearing in industrial applications where heat is generated during operation. Thanks to the combination of a 40 mm shaft diameter and the solid 110 mm outer ring, the 6408 series can withstand high peak loads. The component, which has no groove or flange on the outer ring, can be fitted precisely into cylindrical housing bores and contributes to uniform force transmission on stationary or rotating shafts.

What does the C3 bearing clearance mean for your bearing selection?

The suffix designation C3 indicates a slightly increased radial clearance compared with the standard version. This radial operating clearance compensates for thermal expansion of the shaft and inner ring due to temperature differences without the rolling elements becoming jammed. In the case of tight fits, the C3 classification also counteracts any impermissible reduction in bearing clearance. For the open design, a clean housing environment is required, as there are no integrated seals to protect against dust or liquids.
