Cylindrical Roller Bearings FAG NJ2212 -E-XL-TVP2
The FAG NJ2212 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 60x110x28 mm, offers high radial load-carrying capacity in a compact design as a single-row support bearing.
The NJ2212 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. Thanks to the line contact between the cylindrical rollers and the raceways, this design can accommodate very high radial loads. The FAG bearing features fixed flanges on one side of both the outer and inner rings, enabling it to function as a support bearing. The open design allows for direct integration into existing lubrication circuits or individual initial greasing on site.
In which bearing arrangements does the NJ2212 -E-XL-TVP2 cylindrical roller bearing prove its worth?
Design engineers and maintenance personnel use this design primarily in shaft mountings where significant radial loads are present and axial guidance in one direction is required. As the inner ring is removable on one side, the bearing accommodates axial forces in one direction and allows for longitudinal compensation of the shaft towards the opposite side. At the same time, the separable design facilitates the separate installation of the inner and outer rings into the housing and shaft.
What are the distinctive features of the NJ design with a polyamide cage?
The abbreviation TVP2 denotes a solid window cage made of polyamide, which guides the cylindrical rollers precisely. Compared with metal cage designs, this material has a lower weight and contributes to quiet roller guidance. The bearing is designed for an operating temperature range of -30 to +120 degrees and complies with the standard radial bearing clearance as well as the standard tolerance class P0/PN (ABEC 1).
What are the dimensions of the NJ2212 -E-XL-TVP2 cylindrical roller bearing?
This roller bearing has an inside diameter of 60 mm, an outside diameter of 110 mm and a width of 28 mm. These standardised key dimensions enable it to be fitted precisely into housing bores and onto shafts with corresponding interference fits.
What is the function of the NJ design as a support bearing?
In the NJ design, the outer ring has two solid flanges and the inner ring has one solid flange. As a result, the bearing provides positive support for the shaft in one axial direction, whilst allowing compensatory movements within defined limits in the opposite axial direction.
What does the suffix ‘TVP2’ mean for this bearing?
The suffix TVP2 denotes a polyamide window cage that is guided by the rolling elements. The plastic cage is characterised by its low weight and smooth rolling action at operating temperatures of up to 120 degrees.
What is the clearance in the NJ2212 cylindrical roller bearing?
The bearing is manufactured with standard radial bearing clearance, which is designed for typical fit specifications and balanced operating temperatures. The manufacturing accuracy complies with tolerance class P0/PN or ABEC 1, and thus meets the usual requirements in general mechanical engineering.
What is the operating temperature range for this cylindrical roller bearing?
The bearing is designed for operating temperatures ranging from -30 to +120 degrees Celsius. These temperature limits take into account the interaction of the rolling bearing components, including the polyamide cage, during operation.
How is the open bearing protected against dirt and lubricant loss?
As the NJ2212 -E-XL-TVP2 model is manufactured without integrated sealing washers, sealing is achieved via the surrounding housing structure. Depending on the ambient conditions, external shaft seals or labyrinth systems are used, whilst lubrication is provided by grease or oil circulation systems.
