Cylindrical Roller Bearings FAG NJ2320 -E-XL-TVP2-C3
The FAG NJ2320 -E-XL-TVP2-C3 cylindrical roller bearing is an open support bearing with a 100 mm bore designed to withstand high radial loads.
The FAG NJ2320 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing for industrial bearing arrangements. With key dimensions of a 100 mm bore diameter, a 215 mm outer diameter and a width of 73 mm, this roller bearing primarily accommodates radial loads. Thanks to the NJ design, this version serves as a support bearing: the inner ring has a fixed flange and can be removed from one side, allowing axial displacement in one direction to be compensated for.
What loads does the NJ2320 -E-XL-TVP2-C3 cylindrical roller bearing support?
Bearing arrangements subjected to heavy radial loads constitute the primary application for this design. Due to the line contact of the cylindrical rollers, the bearing withstands high radial forces. In combination with a suitable mating bearing, the support bearing design guides shafts whilst simultaneously supporting one-sided axial forces. The outer ring is designed without a groove or lubrication bore.
What are the benefits of the polyamide cage and the C3 clearance?
The material of the polyamide cage (TVP2) guides the cylindrical rollers precisely and reduces the weight inside the bearing. Together with the slightly increased radial clearance (C3), functionality is maintained even under operational heating. As this is an open design without an integrated seal, users can specifically tailor the lubricant and external sealing to the permissible temperature range of -30 to +120 degrees.
What are the dimensions of the NJ2320 -E-XL-TVP2-C3 cylindrical roller bearing?
The dimensions are 100 mm bore diameter, 215 mm outer diameter and 73 mm width. The outer ring has no additional circumferential groove or lubrication bore, and the bearing is designed as a single-row type.
What does the ‘NJ’ design designation mean for this cylindrical roller bearing?
The NJ design denotes a support bearing. The outer ring has two solid flanges, whilst the inner ring has a single flange. This allows the inner ring to be removed from one side. The bearing compensates for axial displacement of the shaft in one direction and absorbs axial forces in the opposite direction.
What is the purpose of the increased bearing clearance C3?
Bearing clearance class C3 denotes a slightly increased radial bearing clearance compared with the standard range. This increased clearance between the cylindrical rollers and the raceways compensates for thermal expansion caused by operating heat. Furthermore, C3 enhances mobility in the case of fixed fits on the shaft or housing.
What are the characteristics of the TVP2 polyamide cage?
The suffix TVP2 denotes a polyamide cage. This material is characterised by its low weight and good damping properties. The polyamide cage guides the cylindrical rollers smoothly and contributes to quiet operation within the specified temperature range.
What is the operating temperature range for the bearing?
The permissible temperature range is between -30 and +120 degrees. Within these limits, the bearing components and the polyamide cage retain their mechanical strength. When designing the system, care must be taken to ensure that the lubricant used is also approved for these operating temperatures.
How is the open cylindrical roller bearing lubricated?
As an open bearing without integrated sealing washers, this version is not pre-lubricated at the factory. Depending on the design, lubrication is provided either by the system’s lubricating oil or by external grease. The housing requires its own sealing elements to prevent contamination and lubricant loss.
