Deep Groove Ball Bearings SKF 6014 /C4

The SKF 6014/C4 deep-groove ball bearing, with dimensions of 70x110x20 mm and a C4 clearance, offers reliable operation even under high temperatures.

The 6014/C4 deep groove ball bearing is a single-row radial ball bearing made from standard 100Cr6 rolling-element steel, designed to withstand radial loads as well as axial forces in both directions. The SKF Explorer quality version combines standardised dimensions with high material purity of the steel. Thanks to its open design without integrated seals, this bearing is suitable for applications where lubrication is provided by the customer using lubricating oil or grease within a sealed housing.

For which operating conditions is the 6014/C4 deep groove ball bearing suitable?

Design engineers primarily select this version for shaft bearings where significant temperature differences occur between the inner ring and the outer ring during operation. Typical applications include bearing arrangements where heat is generated by the rotating shaft. The ball bearing primarily absorbs radial forces and guides the shaft axially in both directions. The sheet steel cage guides the rolling elements evenly across the entire permissible temperature range from –20 to +150 degrees Celsius.

What does the C4 clearance rating mean for your design?

The suffix C4 indicates a significantly increased radial clearance, which exceeds both the standard clearance class and the C3 grade. If tight fits on the 70 mm shaft or operational thermal expansion restrict the operating clearance, this design margin helps to prevent the rolling elements from becoming stressed. Furthermore, manufacture to tolerance class P6 or ABEC 3 results in reduced runout and dimensional deviation compared with the standard tolerance class, ensuring precise shaft guidance.
