Deep Groove Ball Bearings SKF 6012 /C3

The SKF 6012/C3 deep groove ball bearing combines dimensions of 60x95x18 mm with increased radial clearance for industrial applications subject to thermal stress.

The 6012 /C3 deep groove ball bearing is a single-row radial ball bearing in an open design, made from standard rolling-element bearing steel (100Cr6). As a model in the SKF Explorer performance class, this bearing combines optimised internal geometries with tight manufacturing tolerances to tolerance class P6 (ABEC 3). This design primarily accommodates radial forces and supports shafts even under axial loads in both directions. With key dimensions of a 60 mm bore, 95 mm outside diameter and 18 mm width, the bearing is suitable for demanding industrial applications.

Under what operating conditions is the 6012/C3 deep-groove ball bearing used?

This rolling bearing is the preferred choice when temperature differences occur between the inner and outer rings during operation, or when tight fits are specified. The open design allows for the direct circulation of lubricating oil or grease from the housing system. Thanks to its temperature-resistant sheet steel cage, the bearing is designed for use in a temperature range from -20 to +150 degrees.

What does the C3 clearance rating mean when designing the bearing arrangement?

The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional movement tolerance between the balls and raceways compensates for operational thermal expansion without causing stress or increased running resistance. Tight fits on the 60 mm shaft or within the 95 mm housing also reduce the radial clearance when the bearing is installed. The increased bearing clearance ensures that the bearing operates with the specified operating clearance even at full operating temperature.
