Cylindrical Roller Bearings FAG NJ2220 -E-XL-TVP2
The FAG NJ2220 -E-XL-TVP2 cylindrical roller bearing, with a 100 mm bore, offers high radial load-carrying capacity and acts as a support bearing with an axial guidance function.
The NJ2220 -E-XL-TVP2 cylindrical roller bearing is a single-row roller bearing from FAG for industrial applications involving high radial loads. With a bore diameter of 100 mm, an outer diameter of 180 mm and a width of 46 mm, this design is suitable for heavily loaded bearing arrangements in industrial machinery. The design features a polyamide cage (TVP2) and is rated for operating temperatures ranging from -30 to +120 degrees. As an open bearing, it can be flexibly integrated into existing lubrication systems.
What is the NJ2220 -E-XL-TVP2 cylindrical roller bearing suitable for in mechanical engineering?
This single-row roller bearing is particularly suitable for bearing arrangements where high radial forces act and axial displacement in one direction must be accommodated. Typical applications include compact bearing arrangements in mechanical engineering and gearbox construction, subject to combined loads consisting mainly of radial forces and single-sided axial guidance.
Due to the line contact of the cylindrical rollers, the bearing can accommodate high radial loads. As the inner ring can be removed from one side, the component is easy to install and facilitates time-saving maintenance in confined installation spaces.
What are the distinctive features of the NJ support bearing design with a TVP2 cage?
The NJ design functions as a support bearing: the outer ring has two fixed flanges, whilst the inner ring has one flange. This design allows for axial length compensation of the shaft in one direction and supports axial forces in the opposite direction.
The polyamide cage (TVP2) is characterised by its low weight, elastic running characteristics and quiet operation. When designing the application, it should be noted that the bearing is manufactured with standard radial clearance and complies with tolerance class P0 or ABEC 1.
What are the dimensions of the NJ2220 -E-XL-TVP2 cylindrical roller bearing?
The bearing has an internal diameter of 100 mm, an external diameter of 180 mm and a width of 46 mm. These standardised key dimensions enable it to be fitted precisely into machine housings and onto shafts in accordance with tolerance class P0 or ABEC 1.
What does the ‘NJ’ design designation mean for this bearing?
The NJ design denotes a support bearing with two fixed flanges on the outer ring and one flange on the inner ring. This enables the bearing to accommodate radial forces and unilateral axial forces, whilst compensating for thermally induced changes in the shaft’s length in the opposite direction. The inner ring can be removed from one side for installation.
What are the properties of the TVP2 polyamide cage?
The TVP2 cage is made of polyamide and guides the cylindrical rollers precisely whilst minimising friction. The lightweight cage material reduces inertial forces during changes in rotational speed and promotes smooth running. With this cage, the bearing is designed for a temperature range of -30 to +120 degrees.
What is the clearance in the NJ2220 -E-XL-TVP2 cylindrical roller bearing?
This cylindrical roller bearing is manufactured with standard radial clearance. This standard clearance is suitable for common mounting fits and moderate temperature differences between the inner and outer rings during normal operation. Users should select the appropriate fit and operating temperatures to maintain the required operating clearance.
How is the open cylindrical roller bearing lubricated?
As an open bearing without integrated sealing washers, this version is not factory-filled with grease. Depending on the design, lubrication is carried out using grease or oil via the machine housing. Users select the lubricant and lubrication intervals to suit the respective operating temperature and speed.
What does the XL designation mean at FAG?
At FAG Rolling Bearings, the abbreviation ‘XL’ denotes the X-life design. This design is characterised by optimised raceway surfaces and improved contact geometries on the rollers. This contributes to an even load distribution and helps ensure a long service life under demanding conditions.
