Deep Groove Ball Bearings FAG 6008 -2Z-C3

The FAG 6008 -2Z-C3 single-row deep groove ball bearing (40x68x15 mm) features sheet metal end shields on both sides and an increased C3 radial clearance, making it suitable for a wide range of industrial applications.

The 6008 -2Z-C3 deep groove ball bearing is a single-row radial ball bearing to Normal tolerance class (P0/PN or ABEC 1) made from standard rolling bearing steel 100Cr6. FAG manufactures this version with a bore of 40 mm, an outer diameter of 68 mm and a width of 15 mm. Thanks to the cover on both sides with non-contacting sheet metal shields (2Z), the design protects the bearing interior from coarse dirt particles. This version is suitable for combined loads with a predominantly radial component in industrial drive trains.

What is the 6008 -2Z-C3 deep groove ball bearing suitable for in operation?

This bearing accommodates radial forces as well as axial forces in both directions. The design is particularly suitable for rotating shafts subject to combined loads and with increased speed requirements. The cylindrical outer ring without a groove fits precisely into standardised housing bores. As the gap seals operate without contact, there are no additional friction losses at the sealing surfaces. This is beneficial for applications involving higher speeds.

What is the effect of combining a 2Z seal with C3 bearing clearance?

The suffix C3 indicates increased radial bearing clearance compared with the standard version. This clearance compensates for operational thermal expansion or tight fits on the shaft and housing without the rolling elements becoming jammed. The integrated sheet steel cage guides the rolling elements across the permissible temperature range of –30 to +120 degrees Celsius. The cover plates on both sides retain the lubricant within the bearing and reduce the ingress of solid foreign particles.
