Deep Groove Ball Bearings SKF 6216 /C3

The SKF 6216/C3 single-row deep groove ball bearing, with an inner diameter of 80 mm and an outer diameter of 140 mm, offers proven running characteristics at elevated operating temperatures.

The 6216/C3 deep groove ball bearing is an open radial rolling bearing made from standard 100Cr6 bearing steel, designed for combined radial and axial loads. As it is designed without integrated sealing washers, this ball bearing is suitable for designs featuring external sealing and where lubrication is supplied via a centralised lubrication system or an oil bath. The tolerance class P0/PN (corresponding to ABEC 1) ensures a precise fit in standardised bearing seats.

What loads can the 6216 /C3 deep groove ball bearing withstand?

This single-row rolling bearing primarily withstands radial forces, but also supports shafts in both axial directions. Typical applications include bearing arrangements subject to combined loads in general mechanical engineering. Thanks to the sheet steel cage and the absence of contact seals, the rolling elements move with low rotational resistance. This characteristic is advantageous for applications involving higher speeds where lubrication is provided by oil or targeted grease relubrication.

What distinguishes the version with C3 clearance?

The suffix C3 indicates an increased radial bearing clearance compared with the standard version. This additional clearance between the balls and raceways is required when significant temperature differences occur between the inner and outer rings during operation. Tight fits on the shaft also expand the inner ring, thereby reducing the internal clearance. The C3 classification helps to prevent components from becoming stressed and supports the permissible temperature range of –20 to +150 degrees Celsius.
