Deep Groove Ball Bearings SKF 6214 /C3

The SKF 6214/C3 open deep-groove ball bearing, with dimensions of 70 × 125 × 24 mm and C3 bearing clearance, allows for thermal expansion under radial and axial loads.

The 6214/C3 deep groove ball bearing is a single-row rolling bearing from SKF, manufactured from standard bearing steel (100Cr6) with a sheet steel cage. This design combines a 70 mm inner bore with an outer diameter of 125 mm and a width of 24 mm. As an open bearing without an integrated seal, this variant is designed for installation environments with an external lubricant supply via oil or grease. The design accommodates radial forces as well as axial forces acting in both directions.

For which operating conditions is the 6214 /C3 deep groove ball bearing designed?

The 6214 /C3 deep groove ball bearing is suitable for bearing arrangements with a 70 mm shaft diameter where combined loads occur. As it is manufactured to tolerance class P0 (standard tolerance or ABEC 1), the component fits into cylindrical housing seats without a flange or groove. The permissible temperature range extends from –20 to +150 degrees Celsius, thereby covering applications with significant operational heating.

What does the suffix /C3 mean for bearing selection?

The suffix C3 indicates a slightly increased radial clearance compared with standard clearance. When the shaft and inner ring heat up during operation, they often expand more than the outer ring. The increased radial clearance helps to ensure that the rolling elements do not jam and that unnecessary friction is avoided. Before installation, it must be checked whether the operating temperature and fit selection require this additional radial clearance in order to avoid bearing stresses.
