Deep Groove Ball Bearings SKF 6008 -2Z/C3

The SKF 6008 -2Z/C3 deep groove ball bearing, with dimensions of 40x68x15 mm, C3 clearance and sheet metal shields on both sides, offers low-friction operation at elevated operating temperatures.

This single-row deep-groove ball bearing 6008 -2Z/C3, made from standard rolling-element steel (100Cr6), primarily accommodates radial forces as well as axial loads in both directions. The Explorer bearing version, in tolerance class P6 or ABEC 3, is characterised by high running accuracy. A sturdy sheet steel cage guides the rolling elements evenly between the raceways. With key dimensions of 40 mm inner diameter, 68 mm outer diameter and 15 mm width, the roller bearing is suitable for demanding applications in mechanical engineering.

In which operating environments does the 6008-2Z/C3 deep-groove ball bearing prove its worth?

Design engineers and users prefer to use this bearing unit in rotating shaft systems with constant speeds and combined loads. The metal end shields on both sides keep out coarse dirt particles without causing friction on rotating components. The bearing unit retains its mechanical properties at operating temperatures between –20 and +120 degrees. The absence of abrasive sealing elements helps to minimise torque and reduces heat build-up at the bearing location.

What are the distinctive features of the C3 bearing clearance and the 2Z cover plates?

The C3 designation indicates increased radial bearing clearance. This defined clearance compensates for thermal linear expansion when the bearing heats up, as well as radial constriction caused by tight fits. This counteracts any straining of the rolling elements during operation. The 2Z cover on both sides acts as a non-contact gap seal: it shields the factory-applied lubricant from contamination and generates no frictional resistance. This combination promotes low-friction operation at higher speeds.
