Cylindrical Roller Bearings FAG N218 -E-XL-M1-C3

The FAG N218 -E-XL-M1-C3 single-row cylindrical roller bearing, with a 90 mm bore, offers high radial load-carrying capacity and axial length compensation when used as a non-locating bearing.

The N218 -E-XL-M1-C3 cylindrical roller bearing is designed to accommodate high radial loads in demanding industrial drives. With key dimensions of a 90 mm bore, 160 mm outer diameter and 30 mm width, this FAG rolling bearing complies with tolerance class P0/PN or ABEC 1. Designed as an open bearing, it can be integrated directly into housing-side lubrication circuits. The N design allows unimpeded longitudinal displacement of the shaft relative to the housing thanks to the flangeless outer ring.

How does the N218 -E-XL-M1-C3 cylindrical roller bearing support length compensation as a non-locating bearing?

The design as a floating bearing accommodates high radial loads and compensates for axial length changes in the shaft. As the outer ring is designed to be removable on both sides, the inner and outer rings can be fitted separately. This modular design simplifies installation and maintenance in compact assemblies. In bearing arrangements based on the fixed-floating principle, the bearing compensates axially for operational thermal shaft expansion.

What do the M1 brass cage and C3 bearing clearance mean for the design?

The version with the M1 brass cage ensures precise guidance of the rolling elements, particularly under high acceleration or vibration loads. In combination with the slightly increased radial clearance (C3), the design helps to prevent thermal seizure caused by temperature differences between the shaft and the housing. The permissible operating temperature range is from –30 to +150 degrees Celsius. When designing the system, it must be borne in mind that the open bearing, which has no groove or lubrication bore on the outer ring, relies on a suitable external housing seal.
