Deep Groove Ball Bearings SKF 6020 /C3

The SKF 6020/C3 deep groove ball bearing, with dimensions of 100 × 150 × 24 mm and increased C3 clearance, offers stable operation for a wide range of industrial applications.

The SKF 6020/C3 single-row deep groove ball bearing is a radial rolling bearing for shafts with a diameter of 100 mm. It accommodates radial forces as well as axial loads in both directions. The open bearing design allows lubrication via the machine’s existing oil or grease circuit. Manufactured from standard 100Cr6 rolling-element bearing steel and fitted with a sheet steel cage, this Explorer-series model is designed for demanding operating conditions in mechanical engineering.

What are the applications for the open deep groove ball bearing 6020 /C3?

The 6020 /C3 deep groove ball bearing is primarily used in bearing arrangements subject to combined loads and with separate housing lubrication. The open design, without sealing washers, is suitable for enclosed housings in which lubricating oil can circulate freely. As the bearing operates at temperatures ranging from -20 to +150 degrees, it is also suitable for designs subject to thermal heating. The outer ring, which has no groove or flange, can be fitted into smooth housing bores with a diameter of 150 mm.

Why is the C3 bearing clearance important for this bearing?

The designation 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 at operating temperatures up to +150 degrees. Furthermore, the C3 clearance helps to prevent seizing if tight fits on the shaft and housing deform the bearing rings during press-fitting. Together with dimensional accuracy to P6 and running accuracy PN, the bearing thus ensures smooth running.
