Deep Groove Ball Bearings SKF 6206 -2Z/C3

The SKF 6206 -2Z/C3 deep groove ball bearing features standardised dimensions of 30x62x16 mm, sheet metal shields on both sides and increased bearing clearance for drives subject to thermal stress.

The SKF 6206 -2Z/C3 deep groove ball bearing is a single-row radial ball bearing made from standard 100Cr6 rolling bearing steel, with a bore diameter of 30 mm, an outer diameter of 62 mm and a width of 16 mm. Designed to accommodate radial and moderate axial loads in both directions, this version features non-contacting sheet steel cover plates on both sides. A sheet steel cage guides the rolling elements evenly along the raceway. The bearing is manufactured to tolerance class P0/PN (ABEC 1), ensuring that the component fits precisely into standardised bearing housings.

What is the 6206-2Z/C3 deep groove ball bearing suitable for?

Industrial drives and rotating shafts constitute the primary field of application for this deep groove ball bearing. Thanks to the non-contact cover plates, coarse dirt cannot penetrate the raceway, whilst lubricant loss is minimised without generating additional frictional heat. Operating at temperatures ranging from -20 to +120 degrees, the unit is used in shaft bearings subject to continuous rotation. The design directly absorbs radial forces and guides shafts with low rotational resistance.

What does the C3 bearing clearance mean for this design?

The designation C3 indicates a slightly increased radial bearing clearance compared with the standard bearing design. This additional clearance between the rolling elements and raceways compensates for thermal expansion when the shaft or housing heats up. Even with tight fits, the C3 clearance helps to prevent the bearing from seizing during operation. Together with the Z-type end plates on both sides, this ball bearing is suitable for applications involving higher speeds, where low friction and thermal reserves are equally important.
