Deep Groove Ball Bearings SKF 6219 /C3

The single-row SKF deep groove ball bearing 6219 /C3 (95x170x32 mm) offers thermal reserves for demanding industrial drives thanks to its increased C3 clearance.

The 6219/C3 deep groove ball bearing is an open, single-row radial ball bearing made from 100Cr6 rolling bearing steel for industrial applications. With an inner diameter of 95 mm, an outer diameter of 170 mm and a width of 32 mm, this rolling bearing primarily absorbs radial forces and supports axial forces in both directions. Thanks to the integrated sheet steel cage, the design ensures low-vibration movement of the rolling elements. The open design allows for direct lubrication via the housing system within a temperature range of -20 to +150 degrees.

What is the 6219 /C3 deep groove ball bearing suitable for?

The 6219 /C3 deep groove ball bearing is primarily used in through-shaft mountings and industrial drives subject to combined radial and axial loads. The design is suitable for applications where external lubrication systems provide the lubricant supply. As the outer ring has no groove or flange, the component can be fitted flush into cylindrical housing bores. In shaft mountings with elevated operating temperatures, this design provides the necessary space to accommodate thermally induced material expansion.

What effect does the C3 bearing clearance have on this open rolling bearing?

The designation C3 indicates a slightly increased radial bearing clearance compared with the standard tolerance class. This additional clearance compensates for radial play when the inner ring and shaft are constricted by tight fits, or when high operating temperatures lead to temperature differences between the inner and outer rings. For your design, this means smooth running without premature jamming of the rolling elements. As the bearing is of an open design, a suitable housing seal is recommended to prevent the ingress of dirt and loss of lubricant during operation.
