Deep Groove Ball Bearings SKF 6005 -2Z/C3

The SKF deep groove ball bearing 6005 -2Z/C3, with a 25 mm bore, non-contact end shields and increased bearing clearance, offers a suitable solution for rotating shafts.

The SKF 6005 -2Z/C3 deep groove ball bearing is a single-row radial ball bearing made from case-hardened 100Cr6 rolling-element steel in the Explorer design. It primarily accommodates radial forces as well as axial loads in both directions. The sheet metal covers on both sides protect the grease filling inside whilst keeping out contaminants. Manufactured to the higher dimensional accuracy class P6 and running accuracy class P5, it ensures low-vibration operation.

In which operating conditions does the 6005-2Z/C3 deep-groove ball bearing prove its worth?

This bearing is specifically designed for applications involving higher speeds and combined loads. The integrated steel sheet cage guides the rolling elements with low friction. With a permissible operating temperature range of –20 to +120 degrees, the rolling bearing can be operated under demanding thermal conditions. As the outer ring is designed without a flange or groove, the bearing fits precisely into cylindrical housing bores.

What is the function of the C3 bearing clearance and the 2Z cover plates?

The suffix ‘C3’ denotes a slightly increased radial bearing clearance compared with the standard clearance. This design clearance compensates for thermal expansion caused by heating during operation or dimensional changes resulting from tight fits, thereby preventing the bearing from becoming stressed. The cover plates on both sides, made of sheet steel, form non-contact gap seals. They generate no sliding friction and retain the grease inside the bearing, whilst reducing the ingress of particles.
