Deep Groove Ball Bearings SKF 6208

The SKF 6208 deep groove ball bearing is an open, single-row rolling bearing with a 40 mm bore, an 80 mm outer diameter and a width of 18 mm, made from 100Cr6 bearing steel.

As a single-row radial ball bearing, the SKF 6208 is one of the most widely used rolling bearings in industrial mechanical engineering. With a bore of 40 mm, an outside diameter of 80 mm and a width of 18 mm, the bearing primarily withstands radial forces, but is also suitable, to a limited extent, for axial loads in both directions. Manufactured from standard roller bearing steel (100Cr6) in the Explorer design, this bearing type features a sheet steel cage. The permissible temperature range is from –20 to +120 degrees Celsius.

What operating conditions does the 6208 open deep-groove ball bearing require?

The open deep-groove ball bearing 6208 is suitable for bearing arrangements subject to predominantly radial loads and limited axial forces in both directions. As this version has no integrated seals, the lubricant can be supplied directly via the surrounding housing or a central lubrication system. Installation is recommended in clean or separately sealed mounting spaces to prevent dirt particles and moisture from reaching the raceways. The cylindrical outer ring, which has no flange or ring groove, allows for mounting in standardised housing bores.

What are the key features of the 6208 deep-groove ball bearing with standard bearing clearance?

This design features standard radial clearance and tolerance class P0/PN (ABEC 1). This ensures standardised dimensional and concentricity accuracies for industrial applications. By omitting contact sealing lips, the bearing remains free from additional frictional resistance, which helps to maintain a low operating temperature. When designing the application, it is important to ensure that a continuous supply of lubricant is available and that the temperature range of -20 to +120 degrees Celsius is maintained.
