Deep Groove Ball Bearings FAG 6214 -Z-C3

The 6214-z-c3 deep-groove ball bearing from FAG Wälzlager, with an outer diameter of 125 mm and a single-sided sheet metal cover, offers reliable protection against the ingress of dirt.

This single-row deep-groove ball bearing 6214-z-c3 primarily accommodates radial forces as well as axial loads in both directions. Manufactured from standard rolling-bearing steel, the component features a cylindrical bore, an outer diameter of 125 mm and a width of 24 mm. This design is manufactured by FAG Rolling Bearings and is suitable for demanding bearing applications involving continuous rotational movement in a wide variety of mechanical designs.

What are the key operational characteristics of the 6214-z-c3 deep groove ball bearing?

It is primarily installed in shaft bearings where combined forces and medium to high speeds occur. As the bearing absorbs radial loads, it performs well in designs with rotating shafts. A robust sheet steel cage guides the rolling elements with minimal vibration within the deep raceways. The single-sided cover partially shields the interior from coarse dirt particles, whilst the open opposite side can accommodate lubricant from the housing if required.

What do the C3 bearing clearance and the single-sided cover mean when selecting a bearing?

The designation C3 stands for a slightly increased radial bearing clearance, i.e. the radial play between the balls and raceways when the bearing is unmounted. This additional clearance compensates for operational thermal expansion and helps to prevent the rolling elements from seizing up when the shaft heats up. Design engineers also take the single-sided cover into account during design: they position the covered side towards the source of contamination, whilst the open side faces the internal lubrication point.
