Cylindrical Roller Bearings FAG N211 -E-M1

The FAG N211 -E-M1 cylindrical roller bearing is a non-locating bearing with a brass cage, measuring 55 x 100 x 21 mm.

The N211 -E-M1 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for radial loads. Due to its N design, the inner ring has two fixed flanges, whilst the outer ring is flangeless and removable on both sides. This design allows axial displacement of the shaft relative to the housing to be compensated for directly within the bearing. With standard radial clearance and tolerance class P0/PN, this open roller bearing is suitable for conventional industrial drive trains.

What is the N211 -E-M1 cylindrical roller bearing suitable for in industrial plant?

Typical applications include rotating shafts where radial loads occur and thermal linear expansion of the shaft must be accommodated. As a non-locating bearing, the N211 -E-M1 cylindrical roller bearing counteracts axial stresses in the bearing arrangement. With a permissible temperature range of –30 to +150 degrees, the component covers a wide range of operating conditions in mechanical engineering. The open design requires lubrication via the surrounding housing using lubricating oil or grease.

What is the function of the brass cage in the N design?

The designation M1 indicates the brass cage, which guides the cylindrical rolling elements. Brass is characterised by high mechanical strength and withstands dynamic loads. As the outer ring has no groove and no lubrication bore, the lubricant supply must be provided via the bearing environment as a design feature. Because the outer ring can be removed from both sides, the shaft and housing can be fitted separately.
