Deep Groove Ball Bearings SKF 608 -2Z

The SKF 608-2Z deep groove ball bearing is a compact miniature bearing with an 8 mm bore, sheet metal end shields on both sides and tight manufacturing tolerances.

The 608-2Z deep groove ball bearing is one of the most widely used miniature rolling bearings for small-diameter rotating shafts. As a single-row bearing in the SKF Explorer performance class, this component combines a slim design with a defined level of manufacturing quality. With dimensions of 8 mm inner diameter, 22 mm outer diameter and 7 mm width, the unit primarily accommodates radial forces as well as axial loads in both directions. Manufactured from 100Cr6 rolling bearing steel, the model operates with standard radial clearance.

What is the 608-2Z deep groove ball bearing suitable for?

The bearing is primarily used in compact small electric drives, hand tools, fans, as well as precision mechanical assemblies and measuring instruments. Thanks to the sheet steel cage and the sealed design, the construction retains its dimensional stability. The permissible temperature range extends from –20 to +120 degrees Celsius, allowing this rolling bearing to be flexibly integrated into workshop and industrial environments.

What is the function of the 2Z cover plates and P6/P5 tolerances?

The suffix ‘-2Z’ denotes two non-contacting cover plates made of sheet steel. This design protects the interior from coarse dirt particles without generating additional friction or heat. The bearing is therefore suitable for higher speeds. Another key feature is the precision of manufacture: dimensional accuracy complies with tolerance class P6, whilst running accuracy is to class P5. This ensures smooth, low-vibration operation on precisely fitted shafts.
