Deep Groove Ball Bearings SKF 6224 /C3

The SKF 6224 /C3 deep groove ball bearing, with dimensions of 120x215x40 mm and a C3 clearance, provides a reliable foundation for demanding radial loads.

The 6224 /C3 deep groove ball bearing is a single-row rolling bearing from SKF in an open design. With a bore of 120 mm, an outside diameter of 215 mm and a width of 40 mm, this bearing primarily withstands radial loads. The bearing is made from standard rolling-element steel (100Cr6) with matching rolling elements and features a guided sheet steel cage. The outer ring is cylindrical in design and has no flange or groove, which means the ball bearing can be fitted directly into precision-machined housing bores.

In which applications does the 6224/C3 deep-groove ball bearing prove its worth?

This deep-groove ball bearing is suitable for applications in general mechanical engineering where medium to high radial forces and moderate axial forces are present. The permissible temperature range is from –20 to +150 degrees Celsius. Thanks to its open design, the lubricant reaches the rolling elements and raceways unimpeded. This version is intended for bearing arrangements with an external lubricant supply via continuous oil circuits or external grease chambers.

What characterises the C3 radial clearance in the 6224 deep-groove ball bearing?

The C3 designation indicates a slightly increased radial clearance compared with the standard version. This increased radial clearance serves to compensate for operational thermal expansion of the bearing rings. If temperature differences arise between the inner and outer rings, or if tight fits are selected for the shaft and housing, the C3 clearance helps to prevent the rolling elements from seizing. The tolerance class corresponds to P0/PN or ABEC 1. When designing the assembly, ensure that the housing is suitably sealed to prevent the ingress of contaminants.
