Deep Groove Ball Bearings SKF 6000 /C3

The SKF 6000/C3 single-row deep-groove ball bearing, with a 10 mm bore, sheet steel cage and increased bearing clearance, ensures smooth running under thermal loads.

The 6000/C3 deep groove ball bearing is an open, single-row radial ball bearing made from standard rolling-element steel (100Cr6) with the main dimensions of a 10 mm bore, 26 mm outer diameter and 8 mm width. Thanks to its SKF Explorer design, as well as its increased dimensional accuracy (P6) and running accuracy (P5), this bearing is suitable for demanding shaft mountings. The design without sealing washers allows for direct lubrication via the housing, whilst the robust sheet steel cage guides the rolling elements with precision.

What is the 6000/C3 deep groove ball bearing suitable for in operation?

Design engineers and maintenance personnel primarily use this bearing design in compact units where radial forces are the main consideration and moderate axial forces in both directions are supported. Typical applications include compact shaft mountings with an external lubrication circuit. As the bearing is designed for operating temperatures ranging from –20 to +150 degrees, it operates reliably within protected housing designs even when subjected to significant heat build-up during continuous operation.

What does the C3 radial clearance mean for this open bearing?

The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This additional radial clearance prevents the rolling elements from becoming jammed if the inner ring expands more than the outer ring due to shaft heating. Similarly, the C3 bearing clearance compensates for the expansion of the inner ring, which is unavoidable with tight fits on the 10 mm shaft. When fitting open bearings, care must always be taken to ensure a clean installation environment, as there are no sealing washers to protect against dirt.
