Deep Groove Ball Bearings FAG 6208 -RSR

The 6208-RSR deep groove ball bearing from FAG Rolling Bearings, with a 40 mm bore and a single-sided RSR seal, offers reliable protection in compact installations.

With the 6208-RSR deep groove ball bearing, you are choosing a single-row radial ball bearing that complies with standard specifications for industrial use. This roller bearing from FAG Wälzlager has a bore of 40 mm, an outer diameter of 80 mm and a width of 18 mm. As it is manufactured from standard 100Cr6 rolling bearing steel, the design primarily withstands radial loads as well as moderate axial loads. A sheet steel cage guides the rolling elements evenly into the deep raceways of the inner and outer rings.

What are the applications of the 6208-RSR deep groove ball bearing in industry and trade?

This rolling bearing is used in industrial drives and rotating assemblies. This version is suitable for shafts with a diameter of 40 mm, where one side of the bearing seat needs to be shielded against the ingress of dirt, whilst the other side remains facing the interior of the housing. Thanks to the standard radial clearance, the bearing runs smoothly at typical operating temperatures between –30 and +100 degrees. It is fitted into appropriately sized cylindrical bearing seats.

What is the function of the single-sided RSR seal in this rolling bearing?

The designation -RSR stands for a single-sided, sliding seal. On the outer side, it serves to reduce the ingress of dirt and moisture into the bearing interior. At the same time, the open opposite side allows lubrication from inside a machine housing if required. As the cylindrical outer ring is manufactured without a groove or flange, axial retention is provided by the surrounding housing structure.
