Cylindrical Roller Bearings FAG NJ326 -E-XL-TVP2
The NJ326 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager, with dimensions of 130 × 280 × 58 mm, offers high radial load-carrying capacity as a separable support bearing.
The NJ326 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. Thanks to the modified line contact between the cylindrical rollers and the raceways, the design can withstand very high radial loads. In the NJ version, the bearing has two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the assembly supports the shaft in the axial direction, whilst the opposite side allows for unrestricted longitudinal movement.
What is the function of the NJ326 -E-XL-TVP2 cylindrical roller bearing in the bearing assembly?
This radial roller bearing is primarily used in heavy-duty gearboxes, industrial drives and general mechanical engineering. Thanks to the NJ design, the bearing acts as a classic support bearing. It withstands heavy radial loads and reliably guides shafts axially in one direction. As the inner ring can be removed from one side, installation can be carried out flexibly in separate stages. This simplifies assembly as well as subsequent maintenance work.
What are the advantages of the TVP2 polyamide cage?
The designation TVP2 indicates a solid polyamide cage. This cage is characterised by its low weight, which reduces inertial forces during operation. The material ensures smooth guidance of the rollers. The open bearing is designed for operating temperatures ranging from -30 to +120 degrees. Lubrication is provided via the housing design, as the outer ring has no lubrication groove.
What characterises the NJ design in the NJ326 -E-XL-TVP2 cylindrical roller bearing?
The NJ design features two fixed flanges on the outer ring and one flange on the inner ring. This enables the bearing to withstand not only high radial forces but also axial loads from one direction. Furthermore, the inner ring can be removed from one side, which facilitates the separate assembly of both bearing rings.
What are the dimensions of this cylindrical roller bearing?
The bearing has an inside diameter of 130 mm, an outside diameter of 280 mm and a width across flats of 58 mm. These dimensions correspond to the standardised nominal dimensions for the NJ326 series. The bearings are manufactured to the standard tolerance class P0 or ABEC 1.
What does the suffix ‘TVP2’ mean in the designation of FAG rolling bearings?
The abbreviation TVP2 refers to a solid polyamide cage with roller guidance. The plastic cage reduces the weight of the component compared with metal cages. Furthermore, the material dampens vibrations and is characterised by good emergency running properties whilst ensuring smooth operation.
What is the clearance in the NJ326 -E-XL-TVP2 cylindrical roller bearing?
This bearing is manufactured with standard radial clearance. This design is suitable for standard operating conditions without excessive heating or extremely tight fits on the shaft and housing. The specified radial clearance serves to ensure that the cylindrical rollers can rotate freely under normal operating loads.
What is the operating temperature range for the bearing?
The permissible operating range is from -30 to +120 degrees. This range is essentially limited by the material of the polyamide cage. To ensure trouble-free operation, the lubricant and external seal must be suited to the prevailing ambient temperature.
How is the open cylindrical roller bearing lubricated?
As the outer ring has neither a lubrication groove nor lubrication holes, the lubricant is supplied from the side via the bearing housing. You can operate the open bearing using either grease or lubricating oil. An effective housing seal protects against the ingress of dirt and moisture.
