Deep Groove Ball Bearings FAG 6216 -Z-C3

The FAG 6216 -Z-C3 deep groove ball bearing accommodates radial loads and, with dimensions of 80x140x26 mm, provides increased clearance to allow for thermal expansion.

The FAG 6216 -Z-C3 deep groove ball bearing is a single-row radial ball bearing made from standard rolling bearing steel 100Cr6. The bearing has a bore of 80 mm, an outer diameter of 140 mm and a width of 26 mm. Designed primarily for radial forces, this bearing also accommodates moderate axial forces in both directions. A sheet steel cage guides the rolling elements evenly into the deep raceways of the inner and outer rings.

What is the 6216 -Z-C3 deep groove ball bearing suitable for in operation?

This radial deep-groove ball bearing is primarily used in shaft mountings where temperature differences occur between the inner and outer rings during operation. Thanks to the C3 clearance, the component compensates for thermal expansion without the rolling elements becoming jammed. This design proves its worth where tight fits reduce internal clearance. The single-sided Z-cover protects the interior from coarse particles, whilst the open opposite side allows for a targeted supply of lubricant from the machine housing.

What do the designations Z and C3 mean for your design?

The suffix ‘Z’ denotes a cover plate made of profiled sheet metal that is pressed in on one side. This plate rotates without contact and does not cause any additional frictional torque on the shaft. The designation C3 indicates an increased radial bearing clearance in the as-supplied condition, i.e. greater internal clearance than in the standard P0 class. This ensures that the required rotational freedom is maintained after press-fitting onto the mating surfaces and during operational heating.
