Deep Groove Ball Bearings FAG 6216 -2RSR-C3

The FAG 6216 -2RSR-C3 deep groove ball bearing, measuring 80x140x26 mm and featuring RSR seals on both sides and a C3 clearance, provides effective protection for industrial shaft mountings.

The FAG 6216 -2RSR-C3 deep groove ball bearing is a single-row radial ball bearing made from standard rolling-element steel (100Cr6) for shafts with a diameter of 80 mm. It accommodates radial forces as well as axial loads in both directions. This version has an outer diameter of 140 mm and a width of 26 mm. Fitted with a sheet steel cage and seals that seal on both sides, the bearing is suitable for industrial shaft arrangements with increased requirements for sealing performance and thermal clearance.

What is the 6216-2RSR-C3 deep groove ball bearing suitable for?

This rolling bearing is suitable for applications in general mechanical engineering involving rotating shafts under demanding environmental conditions. The seals, which seal on both sides, keep the lubricant inside the bearing whilst preventing dust, moisture and dirt particles from entering the raceways. This design is primarily used on 80 mm shafts where there is a risk of contamination and where thermal expansion may occur. The permissible temperature range is from –20 to +100 degrees Celsius.

What does the C3 bearing clearance mean for the 6216-2RSR-C3 deep groove ball bearing?

The designation C3 indicates a slightly increased radial clearance compared with the standard version. This increased clearance between the rolling elements and the raceways compensates for operational thermal expansion of the shaft or housing. Even with tight fits, the C3 bearing clearance helps to prevent the bearing from becoming stressed during operation. Before installation, in addition to checking the mounting dimensions of 80x140x26 mm, you should verify whether the intended operating temperature and choice of fit require this increased bearing clearance.
