Cylindrical Roller Bearings FAG NU2217 -E-M1

The FAG NU2217 -E-M1 cylindrical roller bearing is a single-row idler bearing with a brass cage, designed for high radial loads on a 85 mm shaft diameter.

The FAG NU2217 -E-M1 cylindrical roller bearing is designed for industrial applications in which high radial forces act on the shaft. With an inner diameter of 85 mm, an outer diameter of 150 mm and a width of 36 mm, this roller bearing is suitable for compact installation spaces. The NU design is characterised by the fact that the inner ring can be removed from both sides. This allows the bearing to compensate for axial length changes in the shaft directly within the bearing, without generating additional stresses in the system.

In which installation situations does the NU2217 design prove its worth?

The NU2217 -E-M1 cylindrical roller bearing primarily functions as a non-locating bearing in shaft mountings subject to purely radial loads. As the outer ring has two solid flanges and the inner ring is flangeless, no internal axial forces arise during axial displacement. This open bearing is designed for a temperature range of –30 to +150 degrees. The design allows thermal length changes in the shaft to be compensated for directly between the raceways.

What is the function of the brass cage in the cylindrical roller bearing?

The built-in brass cage guides the cylindrical rolling elements precisely and withstands mechanical loads. This design is suitable for applications involving vibrations or varying speeds. When designing the system, it must be borne in mind that this is an open bearing without an integrated seal. External sealing of the housing and a suitable lubrication system are therefore required for operation. The bearing is manufactured to tolerance class P0 or ABEC 1.
