Deep Groove Ball Bearings SKF 6200 -Z/C3

The 6200-Z/C3 deep groove ball bearing from SKF Rolling Bearings features compact dimensions of 10x30x9 mm, increased radial clearance and single-sided dust protection.

This single-row deep groove ball bearing 6200 -Z/C3 is primarily designed to withstand radial loads as well as moderate axial forces in both directions. Manufactured from standard 100Cr6 bearing steel in the Explorer design, the bearing is characterised by dimensional accuracy to P6 and running accuracy to P5. A sheet steel cage guides the rolling elements evenly in the deep raceway without a flange on the outer ring.

In which applications does the 6200-Z/C3 deep-groove ball bearing prove its worth?

The bearing is used where high speeds occur alongside temperature differences between the inner and outer rings. With a permissible temperature range of –20 to +150 degrees, it is suitable for compact gear stages as well as general industrial applications in mechanical engineering. The single-sided sheet metal cover protects the interior from coarse contaminants entering from the outside, whilst the open opposite side allows for targeted lubrication from inside the housing where required.

What do the ‘Z’ cover plate and the C3 bearing clearance mean in terms of design?

The suffix ‘Z’ denotes a non-contacting gap seal made of sheet steel on one side of the bearing. Unlike sealing lips that create friction, the cover disc does not generate any additional frictional torque, which is why the bearing runs with low friction. The designation C3 indicates a slightly increased radial bearing clearance. This additional radial clearance compensates for thermal expansion during operation and helps to ensure that tight fits on the shaft or housing do not cause premature stress on the rolling elements. The bearing seat must be matched to the 10 mm bore.
