The FAG NJ2218 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 90 × 160 × 40 mm, offers high radial load-carrying capacity and axial guidance in one direction.
This single-row cylindrical roller bearing, model NJ2218 -E-XL-TVP2, manufactured by FAG, acts as a support bearing and absorbs high radial loads. Thanks to the flange configuration on the inner and outer rings, the bearing also guides the shaft in one axial direction. With a bore diameter of 90 mm, an outer diameter of 160 mm and a width of 40 mm, the roller bearing complies with tolerance class P0/PN (ABEC 1). The component has standard radial clearance and operates within a temperature range of -30 to +120 degrees.
This design is used in bearing arrangements where high radial forces are present and defined axial guidance is required. The NJ design acts as a support bearing: it allows axial displacement in one direction, whilst the fixed ring absorbs axial forces from the opposite direction. As the inner ring can be removed from one side, the bearing can be pressed onto the shaft and housing separately during assembly. This simplifies installation and any necessary maintenance work.
The suffix TVP2 denotes a solid polyamide cage that guides the rollers. This cage is characterised by its low weight, which reduces inertial forces during rapid changes in speed. In addition, the plastic dampens vibrations and contributes to the smooth running of the cylindrical rollers. As this is an open bearing without an integrated seal, lubrication is supplied via the housing. The outer ring is designed without a groove or lubrication bore.
The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This enables the bearing to withstand high radial loads and to support the shaft axially in one direction. In the opposite direction, this design allows for axial displacement, thereby compensating for thermal linear expansion of the shaft without causing stress.
This roller bearing has an internal bore of 90 mm, an external diameter of 160 mm and a total width of 40 mm. These key dimensions determine the required fit on the shaft and in the bearing housing. The dimensional and concentricity tolerances comply with the standard accuracy requirements of tolerance class P0 or ABEC 1.
The abbreviation TVP2 refers to a polyamide window cage. The material reduces the weight of the rotating rolling element set and helps to ensure quiet operation. The cage maintains a uniform distance between the rollers and retains its shape within the specified operating temperature range of -30 to +120 degrees.
The bearing is manufactured with a standard radial clearance. This standard clearance is suitable for common fit selections on the shaft and housing, as well as for normal temperature differences between the inner and outer rings during operation. Provided the fit complies with the relevant standards, this prevents the rolling elements from becoming jammed.
As this model is supplied without sealing washers, the lubricant reaches the rollers and raceways directly. The outer ring has no separate lubrication bore or groove. Lubrication with oil or grease is therefore provided by the housing design, which also acts as a seal against dirt and moisture.
The inner ring can be pulled off axially in one direction. This feature allows the inner ring to be fitted to the shaft and the outer ring to be fitted to the housing separately. This simplifies the installation process, as well as subsequent inspection and maintenance work, particularly in the case of tight fits.
