Cylindrical Roller Bearings FAG NJ2319 -E-XL-TVP2
The FAG NJ2319 -E-XL-TVP2 cylindrical roller bearing, measuring 95 × 200 × 67 mm, can withstand very high radial loads and functions as a support bearing.
The FAG NJ2319 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing designed for demanding industrial applications. With a bore of 95 mm, an outer diameter of 200 mm and a width of 67 mm, this open bearing primarily withstands high radial loads. Due to its design as a support bearing, it guides the shaft in an axial direction, whilst the inner ring remains removable from one side. This facilitates the separate assembly of the bearing rings in mechanical engineering.
What is the NJ2319 -E-XL-TVP2 cylindrical roller bearing suitable for?
This bearing is suitable for bearing arrangements where high radial forces occur and a unidirectional axial thrust must be supported. When used as a support bearing, the NJ version allows for axial changes in the length of the shaft in one direction, thereby compensating for thermal expansion. As it is an open bearing without an integrated seal, it is lubricated directly with oil or grease via an external lubrication system.
What does the version with a polyamide cage and standard clearance mean?
The integrated polyamide cage (TVP2) guides the cylindrical rollers quietly and is characterised by its low weight. Together with its design for temperatures ranging from –30 to +120 degrees, the roller bearing operates smoothly under normal operating conditions. The standard radial bearing clearance and the tolerance class P0/PN or ABEC 1 comply with established standards for dimensional and running accuracy. Before installation, it should be checked whether the ambient media and lubricants are compatible with the polyamide material.
What are the dimensions of the NJ2319 -E-XL-TVP2 cylindrical roller bearing?
With an internal diameter of 95 mm, an external diameter of 200 mm and a width of 67 mm, the bearing has defined key dimensions. These enable a precise fit with the bearing seats on the shaft and in the housing. Due to its open design, the mounting dimensions and the adjacent structure must be precisely matched.
What characterises the NJ design in this rolling bearing?
A characteristic feature of the NJ design is two fixed flanges on the outer ring and one fixed flange on the inner ring. This enables the component to function as a support bearing. In addition to high radial forces, it also accommodates axial guidance forces from one direction, whilst axial displacements in the opposite direction are compensated for within the bearing itself. The inner ring can be removed from one side for installation.
What properties does the polyamide cage (TVP2) offer?
The polyamide cage (TVP2) is characterised by its elastic material properties, low weight and low-noise guidance of the cylindrical rollers. The material helps to reduce friction within the rolling element set. It is suitable for operating temperatures ranging from -30 to +120 degrees Celsius and requires the use of suitable lubricants.
What does tolerance class P0 or ABEC 1 mean?
The P0 or ABEC 1 classification denotes the standard tolerance for dimensional and running accuracy in rolling bearings. It specifies that concentricity, parallelism and dimensional deviations must comply with current industry standards. For bearing arrangements in general mechanical engineering, this precision class offers a good balance between operational reliability and cost-effectiveness.
How is the open bearing lubricated and sealed?
As the bearing has neither cover plates nor sealing washers, protection against dirt and moisture must be provided by the housing design. This is usually achieved using external shaft seals or labyrinth seals. Lubrication is provided by the lubrication system of the overall plant, using either oil or grease, as there is no separate lubrication bore on the outer ring.
What is the permissible temperature range for the bearing?
The permissible temperature range is from -30 to +120 degrees Celsius. This range is largely determined by the resistance of the polyamide cage. When selecting a lubricant, users must ensure that its thermal operating range corresponds to the permissible temperature range of the rolling bearing.
