Deep Groove Ball Bearings FAG 6212 -Z-C3

The FAG 6212 -Z-C3 deep-groove ball bearing, with a 60 mm bore, single-sided sheet metal cover and C3 clearance, offers reliable operation under thermal stress.

The FAG 6212 -Z-C3 deep groove ball bearing is a single-row radial ball bearing with the following main dimensions: 60 mm bore, 110 mm outer diameter and 22 mm width. Thanks to its design with deep raceways, this rolling bearing accommodates radial forces as well as axial forces in both directions. The design, featuring standard bearing steel (100Cr6) for the rings and balls, as well as a guided sheet steel cage, ensures dimensionally stable running characteristics at operating speeds.

In which installation scenarios does the 6212 -Z-C3 deep-groove ball bearing prove its worth?

This design is primarily used in bearing arrangements where thermal influences or tight fits require increased bearing clearance. The rolling bearing is suitable for rotating shafts where one side of the bearing housing needs to be protected from coarse dirt, whilst the open side allows lubricant to enter from inside the housing. Thanks to the flangeless cylindrical outer ring, the bearing can be fitted directly into standard housing bores.

What are the functions of C3 clearance and the Z-type cover plate?

The suffixes define the technical characteristics of this bearing variant. The designation C3 indicates a slightly increased radial bearing clearance compared with the standard version. This increased clearance compensates for operational thermal expansion of the shaft and housing without the rolling elements becoming jammed. The single-sided sheet metal cover plate (Z) operates without contact and does not cause any additional frictional torque. It protects the interior from particles, whilst allowing relubrication or oil circulation on the opposite side.
