The FAG single-row cylindrical roller bearing NJ304 -E-XL-TVP2-C3, with dimensions of 20x52x15 mm, offers high radial load-carrying capacity and axial support with increased bearing clearance.
As a radial roller bearing, the FAG NJ304 -E-XL-TVP2-C3 cylindrical roller bearing absorbs high radial forces. With compact main dimensions of 20 mm bore diameter, 52 mm outside diameter and 15 mm width, this design is suitable for demanding installation locations in mechanical engineering. As this is an open bearing without integrated seals, lubrication is provided flexibly via the housing design. The tolerance class P0/PN or ABEC 1 ensures precise fit dimensions for standardised shaft seats.
The NJ design is characterised by two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, this roller bearing functions as a support bearing that guides shafts in an axial direction and can accommodate axial forces. In the opposite direction, the inner ring – which can be removed from one side – allows for a defined displacement. This feature facilitates the separate assembly of both bearing rings and compensates for thermally induced changes in the shaft’s length during operation without causing binding.
The version with the suffix TVP2 features a lightweight polyamide cage, which promotes quiet running and exhibits low inertial forces during speed changes. At the same time, the slightly increased radial clearance (C3) provides sufficient operating clearance should temperature differences arise between the inner and outer rings, or should tight fits reduce the radial clearance. The permissible temperature range for use is from -30 to +120 degrees, opening up a wide range of applications in mechanical engineering.
The dimensions are 20 mm bore diameter, 52 mm outside diameter and 15 mm width. It is a single-row roller bearing in standard tolerance class P0/PN, with an outer ring that has no groove or lubrication hole.
The designation NJ refers to a design featuring two fixed flanges on the outer ring and one flange on the inner ring. This allows the bearing to function as a support bearing. In addition to high radial forces, it also absorbs axial forces from one direction, whilst permitting axial displacement in the opposite direction.
Bearing clearance class C3 is greater than the standard radial clearance. It reduces the risk of the rollers seizing if fit allowances cause the inner ring to expand or if operational temperature differences arise between the shaft and the housing. This contributes to smooth running.
The abbreviation TVP2 denotes a solid polyamide cage. This material is lighter than metal versions and reduces inertia. Furthermore, the cage is characterised by good damping properties and smooth operation during continuous use.
The permissible operating temperature range is from -30 to +120 degrees. As the bearing is supplied without sliding seal rings, the lubricant selected for the associated assembly has a decisive influence on the actual temperature behaviour during operation.
The inner ring of this support bearing can be removed from one side. This feature makes it possible to press the inner and outer rings onto the shaft and housing independently of one another. When the assembly is fitted, the rollers slide into their final position whilst being guided axially.
