Cylindrical Roller Bearings FAG NJ2309 -E-XL-TVP2
The FAG NJ2309 -E-XL-TVP2 cylindrical roller bearing offers high radial load-carrying capacity with dimensions of 45x100x36 mm and supports shafts axially in one direction.
The NJ2309 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. Rolling elements with line contact between the rollers and raceways absorb high radial forces. The manufacturer, FAG, equips this version with a lightweight polyamide cage, which ensures smooth running. As an open bearing without seals, the component can be flexibly lubricated with oil or grease and integrated into existing lubrication systems.
In which installation situations is the NJ2309 -E-XL-TVP2 cylindrical roller bearing used?
This design is selected for bearing locations where high radial forces are present and single-sided axial restraint is required. Due to its NJ design, the roller bearing serves as a support bearing. In addition to the dominant radial forces, it also absorbs axial guidance forces from one direction. In the opposite direction, the arrangement allows for axial displacement, thereby compensating for operational length changes in the shaft.
What are the distinctive features of the NJ design with a polyamide cage?
The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the inner ring to be removed from one side, which facilitates the installation and removal of both bearing rings. The polyamide cage guides the cylindrical rollers and is designed for a temperature range of -30 to +120 degrees. With standard radial bearing clearance and tolerance class P0/PN or ABEC 1, the component meets standardised requirements in mechanical engineering.
What are the main dimensions of the NJ2309 -E-XL-TVP2 cylindrical roller bearing?
The dimensions are 45 mm internal diameter, 100 mm external diameter and 36 mm width. The outer ring is cylindrical in design and has neither a lubrication groove nor a lubrication bore, meaning that lubricant is supplied from the outside via the bearing end faces.
What does the ‘NJ’ design designation mean for this cylindrical roller bearing?
The designation NJ identifies the bearing as a thrust bearing with two fixed flanges on the outer ring and one fixed flange on the inner ring. In this configuration, the bearing supports a shaft axially in one direction, whilst axial movement remains possible in the other direction. Furthermore, the inner ring can be removed from one side for installation purposes.
What features does the TVP2 polyamide cage offer?
Polyamide is characterised by its low weight and elastic properties. It dampens vibrations and reduces noise during operation. The material limits the permissible operating temperature range of the bearing to between -30 and +120 degrees.
What is the bearing clearance for this model?
This model is manufactured with standard radial bearing clearance. The radial operating clearance lies within the defined standard range for cylindrical roller bearings of this bore size. This design is suitable for normal operating temperatures and standard fit selections on the shaft and housing.
Does the bearing need to be lubricated before commissioning?
As an open bearing without integrated seals, the component requires lubrication with grease or oil prior to commissioning. The bearing housing also requires an external housing seal to retain the lubricant within the bearing and prevent the ingress of dirt and moisture.
Which tolerance class does the component fall into?
Manufacturing is carried out to tolerance class P0/PN, which is also known internationally as ABEC 1. The dimensional and geometric accuracy of the raceways, as well as the edge clearances, meet the general requirements of industrial machinery and plant engineering.
