Deep Groove Ball Bearings FAG 6012 -C3

The FAG 6012-C3 deep-groove ball bearing, with dimensions of 60x95x18 mm and increased C3 clearance, offers reliable concentricity under thermal loads.

The 6012-C3 deep groove ball bearing is a single-row rolling bearing designed primarily for radial loads, which can also accommodate moderate axial forces in both directions. With a bore of 60 mm, an outside diameter of 95 mm and a width of 18 mm, this model is suitable for a wide range of industrial applications. The manufacturer, FAG, produces this bearing from standard roller bearing steel (100Cr6) with a robust sheet steel cage. As it is an open design, the bearing operates with low friction and can be flexibly lubricated via an external lubrication system.

In which applications does the 6012-C3 deep groove ball bearing prove its worth?

This rolling bearing is typically used where rotating shafts with a diameter of 60 mm are supported and significant operating heat is generated. With a temperature range of -20 to +150 degrees, the component is designed for operating environments subject to thermal stress.

Design engineers prefer to use the open design in enclosed spaces. There, the lubricant circulating within the housing directly provides lubrication and ensures continuous heat dissipation from the bearing location.

What distinguishes the C3 bearing clearance in this bearing from the standard version?

The C3 designation indicates a slightly increased radial clearance compared with the standard version. This additional radial clearance compensates for thermal expansion when the inner and outer rings become unevenly heated during operation or when tight fits reduce the bearing clearance. This helps to prevent the rolling elements from becoming stressed and promotes smooth concentric rotation.

As open roller bearings do not have integrated protection against contamination, external seals must be incorporated into the design to prevent the ingress of dirt particles and moisture.
