Deep Groove Ball Bearings SKF 6208 -2RS1/C3

The SKF 6208 -2RS1/C3 deep groove ball bearing combines a 40 mm bore diameter, sealing lips on both sides and C3 clearance for industrial rotary applications subject to temperature gradients.

The SKF 6208 -2RS1/C3 deep groove ball bearing is a single-row radial ball bearing designed to accommodate both radial and moderate axial loads in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel, the component offers high dimensional stability of the hardened raceways. The combination of a factory-fitted seal and a slightly increased bearing clearance promotes smooth running in rotating assemblies where frictional heat or thermal effects influence the radial operating clearance of the components.

What is the 6208-2RS1/C3 deep groove ball bearing suitable for?

This rolling bearing is particularly suitable for industrial applications involving elevated operating temperatures and radial loads. If temperature differences arise between the inner and outer rings during operation, the C3 bearing clearance compensates for the thermal expansion of the rolling elements. At the same time, the sealing lips, which make contact on both sides, prevent external particles and moisture from entering, which is why the bearing is particularly suitable for use in dusty environments.

What features do the C3 bearing clearance and the 2RS1 seal offer?

The 2RS1 design features sealing discs that make contact on both sides, retaining the factory-applied lubricant inside the bearing and preventing the ingress of particles. In addition, the increased C3 radial clearance helps to prevent component distortion in the case of tight fits on the 40 mm shaft or when the bearing heats up. The sheet steel cage guides the rolling elements evenly into the raceways of the flangeless cylindrical outer ring and complies with standard tolerance P0 or ABEC 1.
