Cylindrical Roller Bearings FAG NJ2209 -E-XL-TVP2
The FAG NJ2209 -E-XL-TVP2 cylindrical roller bearing, measuring 45 x 85 x 23 mm, offers high radial load-carrying capacity and axial support in one direction.
The FAG NJ2209 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing with a 45 mm bore, an 85 mm outer diameter and a width of 23 mm. Designs incorporating this open bearing can accommodate high radial loads. The cylindrical rolling elements create line contact with the raceways, giving the component high rigidity. FAG manufactures this model with standard radial clearance in tolerance class P0.
What loads and mounting conditions can the NJ2209 -E-XL-TVP2 cylindrical roller bearing withstand?
The NJ2209 -E-XL-TVP2 cylindrical roller bearing is particularly suitable for bearing arrangements where heavy radial forces act on the shaft. The design as a support bearing also enables it to accommodate axial guidance forces from one direction. As the inner ring is removable from one side, the bearing compensates for axial length changes in the shaft without any binding. The permissible operating temperature range is from –30 to +120 degrees.
What are the distinctive features of the NJ design with a TVP2 polyamide cage?
The designation ‘NJ’ indicates that the outer ring has two fixed flanges, whilst the inner ring has one flange. This geometry allows both bearing rings to be fitted separately, which makes installation easier for workshop fitters. The TVP2 polyamide cage guides the rollers quietly and is characterised by its low weight. As this is an open bearing without a seal, you should select the lubricant appropriate for the application.
What are the dimensions of the NJ2209 -E-XL-TVP2 cylindrical roller bearing?
This cylindrical roller bearing has an inner diameter of 45 mm, an outer diameter of 85 mm and a width of 23 mm. These dimensions comply with the standard specifications for this size. Before fitting, it is advisable to check the shaft seat and housing bore to ensure a precise fit of the two bearing rings.
What does the ‘NJ’ design designation mean for this bearing?
The NJ design denotes a support bearing whose outer ring has two fixed flanges and whose inner ring is fitted with a single flange. This design accommodates radial forces as well as axial guidance forces in one direction. In the opposite direction, the inner ring – which can be removed from one side – allows for axial displacement of the shaft relative to the bearing housing.
What are the characteristics of the polyamide cage fitted?
The suffix TVP2 denotes a polyamide cage. This material reduces the weight of the rotating components within the bearing and contributes to low-vibration, quiet operation. The elastic plastic absorbs dynamic shock loads and is designed for use in a temperature range from -30 to +120 degrees.
How is the open cylindrical roller bearing lubricated?
As the bearing is designed as an open type without integrated seals and without a lubrication bore in the outer ring, lubricant is supplied via the surrounding structure. Depending on the rotational speed and operating conditions, you can operate the cylindrical roller bearing with grease or lubricating oil. External seals in the housing protect against contamination and lubricant loss.
What is the standard radial clearance for this cylindrical roller bearing?
This version features normal bearing clearance (CN), which is designed for standard fit combinations and typical operating temperatures. Bearing clearance refers to the radial play between the rollers and the raceways when the bearing is not installed. It ensures that the bearing can rotate freely after being pressed into place and when heated.
Which tolerance class does the NJ2209 -E-XL-TVP2 cylindrical roller bearing correspond to?
The bearing is manufactured to tolerance class P0, which corresponds to standard tolerance PN and ABEC 1 classification. This class defines the permissible dimensional and runout tolerances for industrial mass production. It meets the standard requirements of mechanical engineering and is designed for a precise fit on the shaft.
