Deep Groove Ball Bearings SKF 6013 /C3

The SKF 6013/C3 deep-groove ball bearing, with dimensions of 65x100x18 mm, an open design and C3 clearance, offers high running accuracy for rotating shafts.

The SKF 6013/C3 single-row deep groove ball bearing is a radial rolling bearing made from standard bearing steel 100Cr6. In the Explorer version, this model combines compact dimensions with precise manufacture to tolerance class P6 or ABEC 3. As the bearing has an open design, the lubricant from the surrounding assembly reaches the rolling elements and raceways unhindered. The sheet steel cage maintains an even spacing between the balls and ensures smooth running at operating temperatures ranging from -20 to +150 degrees.

What is the 6013 /C3 deep groove ball bearing suitable for in operation?

The 6013 /C3 deep groove ball bearing primarily accommodates radial loads as well as moderate axial forces in both directions. The open design is preferably used in enclosed assemblies where centralised oil or grease lubrication is provided. Thanks to the increased C3 bearing clearance, the bearing remains reliable even when temperature differences occur between the inner and outer rings or when tight fits lead to radial expansion. The absence of sealing washers minimises friction losses at higher speeds.

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

The C3 rating indicates a slightly increased radial bearing clearance compared with standard clearance. When the shaft heats up and expands during operation, this additional clearance helps to prevent the rolling elements from becoming jammed in the raceways. In combination with the tight manufacturing tolerance to P6, the bearing operates with low vibration and maintains dimensional stability. When designing the application, it should be noted that the open design requires a clean installation environment and a suitable lubrication concept, as dirt particles can penetrate the interior unhindered.
