Deep Groove Ball Bearings SKF 6216 -2Z/C3

The SKF 6216 -2Z/C3 deep-groove ball bearing, measuring 80x140x26 mm, with cover plates on both sides and a C3 clearance, offers reliable operation under thermal loads.

The 6216 -2Z/C3 deep groove ball bearing is a single-row radial ball bearing made from standard 100Cr6 rolling-element steel. The bearing primarily accommodates radial forces as well as axial loads in both directions. This version features a robust sheet steel cage and complies with the standard tolerance P0/PN. Thanks to its factory specifications, the component is designed for operating temperatures ranging from -20 to +120 degrees.

What operating conditions does the 6216-2Z/C3 deep groove ball bearing cover?

The radial ball bearing is suitable for rotating shafts with a diameter of 80 mm under combined loads. It primarily accommodates radial forces as well as axial forces in both directions. As deep-groove ball bearings roll with low friction, they enable medium to high speeds whilst ensuring smooth running. The cover plates on both sides protect against dirt particles without generating additional frictional heat at the sealing edges.

What do the designations 2Z and C3 mean for your bearing design?

The suffix 2Z indicates sheet metal cover plates on both sides. These form a non-contact gap seal, ensuring that the bearing remains grease-lubricated and runs with low friction. The designation C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional bearing clearance is recommended where a radial loss of clearance occurs due to tight fits on the shaft or housing, or where temperature differences between the inner and outer rings need to be compensated for during operation.
