Deep Groove Ball Bearings FAG 6214 -2RSR-C3

The FAG 6214 -2RSR-C3 deep groove ball bearing offers double-sided sealing protection and increased bearing clearance for shaft diameters of 70 mm with an external diameter of 125 mm.

This single-row deep groove ball bearing 6214 -2RSR-C3 primarily accommodates radial forces as well as axial loads in both directions. Manufactured from standard rolling bearing steel 100Cr6, this design features a robust sheet steel cage. Two sliding RSR sealing lips seal the interior on both sides against dirt particles and moisture. The component covers an operating temperature range of –20 to +100 degrees and operates to the standard tolerance class P0/PN or ABEC 1.

What is the 6214-2RSR-C3 deep groove ball bearing suitable for?

This bearing type is suitable for shaft mountings where effective protection against contamination is required. The double-sided sliding seal ensures that the lubricant remains trapped inside the bearing whilst external particles are kept out. Typical applications are found in general mechanical engineering in designs with a 70 mm shaft, where continuous operation under standard environmental conditions is required.

When is the C3 bearing clearance with a 2RSR seal advantageous?

The C3 designation indicates a slightly increased radial bearing clearance compared with the standard version. This additional clearance compensates for thermal expansion when temperature differences occur between the inner and outer rings during operation. Tight fits further reduce bearing clearance during installation. The combination of a contact seal and increased bearing clearance counteracts stress on the rolling elements, ensuring that rotational movement remains unimpeded even when the bearing heats up.
