Deep Groove Ball Bearings SKF 6008 -Z

The SKF 6008-Z single-row deep groove ball bearing, with dimensions of 40x68x15 mm, offers a compact design and single-sided dust shielding against coarse dirt.

The 6008-Z deep groove ball bearing is a versatile radial ball bearing made from standard rolling-element steel (100Cr6) in the SKF Explorer design. The design is primarily intended to accommodate radial loads as well as moderate axial forces in both directions. A sturdy sheet steel cage guides the rolling elements evenly into the deep raceways. Thanks to its standard radial clearance, this single-row bearing is suitable for applications with standard fit conditions and stable operating temperatures between –20 and +150 degrees Celsius.

In which assemblies is the 6008-Z deep groove ball bearing used?

Typical applications for the 6008-Z deep groove ball bearing are found in general mechanical engineering, on rotating shafts and in enclosed assemblies. Design engineers make specific use of the single-sided sheet metal cover in enclosed housings where the open side faces the oil or grease lubrication source. The metal cover shield protects the interior of the bearing from solid particles on the opposite side. This ensures that the lubricant remains on the rolling elements, whilst the friction torque remains low compared to abrasive seals.

What are the advantages of the Z cover plate in tolerance class P6?

The -Z version features a non-contact gap seal made of sheet steel on one side. As the cover does not rub against the inner ring, no additional frictional heat is generated, which facilitates high rotational speeds. At the same time, this component meets the tighter tolerance class P6 (ABEC 3). This classification denotes greater dimensional and running accuracy compared with the standard tolerance. In combination with the cylindrical outer ring without a groove, the bearing can be fitted precisely into housing bores.
