Deep Groove Ball Bearings FAG 6011 -2RSR

The FAG 6011 -2RSR deep-groove ball bearing, with dimensions of 55 x 90 x 18 mm and a ground seal on both sides, offers effective protection against dust and moisture.

The 6011-2RSR deep groove ball bearing from FAG Rolling Bearings is a single-row radial ball bearing for shafts with a diameter of 55 mm. It primarily accommodates radial loads as well as moderate axial loads in both directions. The version made from standard 100Cr6 rolling-element steel features a robust sheet steel cage and operates to the standard tolerance P0/PN or ABEC 1. Thanks to the factory-applied grease and the abiding seal lips, the lubrication inside is retained. This enables low-maintenance operation in everyday industrial use.

In which applications does the 6011-2RSR deep groove ball bearing prove its worth?

This bearing is suitable for designs where rotating shafts are supported and there is a risk of external contamination. Thanks to the 2RSR seals on both sides, the component performs particularly well in environments with fine dust or splashing water. Design engineers and maintenance personnel utilise the combination of compact dimensions and optimised load-carrying capacity in applications within both enclosed and partially open units.

What is the function of the 2RSR seal on this ball bearing?

The sealing lips, which run along both sides, lie directly against the bearing inner ring and protect the rolling elements from dirt particles. At the same time, they retain the lubricant within the bearing raceway. Compared with open bearings, this eliminates the need for external sealing. When designing the bearing, the permissible temperature range of -20 to +100 degrees must be taken into account. For standard shaft fits, the bearing is designed with normal radial clearance to prevent stress build-up during operation.
