Deep Groove Ball Bearings SKF 6202 -2Z/C3

The SKF 6202 -2Z/C3 deep groove ball bearing, measuring 15x35x11 mm, offers protection against dirt and is suitable for elevated operating temperatures.

The SKF 6202 -2Z/C3 single-row deep groove ball bearing is a versatile rolling bearing designed primarily for radial loads. Manufactured from standard roller bearing steel (100Cr6) in the Explorer design, this component is characterised by dimensional accuracy to tolerance class P6 and running accuracy to P5. With a bore diameter of 15 mm, an outer diameter of 35 mm and a width of 11 mm, the bearing is suitable for compact designs. The sheet metal shields on both sides protect the bearing’s interior from coarse particles.

What is the 6202-2Z/C3 deep groove ball bearing suitable for in industrial applications?

This deep-groove ball bearing is particularly suitable for drives and rotating shafts that require consistent rotational speeds. Thanks to the combination of a sheet steel cage and a temperature range of –20 to +120 degrees, the bearing is suitable for typical environmental conditions in general mechanical engineering. Design engineers use the design without a flange or groove on the outer ring for cylindrical housing bores. This version accommodates radial forces as well as moderate axial forces in both directions.

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

The C3 designation indicates a slightly increased radial bearing clearance. This increased internal clearance compensates for thermal expansion caused by heat build-up during operation and reduces the risk of stress concentration in the case of tight press fits on the shaft and housing. The abbreviation 2Z stands for sheet metal cover plates fitted on both sides. These gap seals do not make contact with the inner ring in a grinding manner, which keeps friction low whilst simultaneously preventing solid contaminants from entering.
