Cylindrical Roller Bearings FAG NJ2208 -E-XL-TVP2
The FAG NJ2208 -E-XL-TVP2 cylindrical roller bearing (40x80x23 mm) is designed to support high radial loads and unilateral axial forces as a support bearing.
The NJ2208 -E-XL-TVP2 cylindrical roller bearing is a single-row roller bearing from FAG designed for heavy-duty mechanical applications. With a bore of 40 mm, an outer diameter of 80 mm and a width of 23 mm, the component offers compact dimensions combined with high radial stiffness. The line contact of the cylindrical rollers enables a robust force transmission in rotating assemblies compared to point-contact raceways.
What is the NJ2208 -E-XL-TVP2 cylindrical roller bearing suitable for?
This rolling bearing acts as a support bearing and primarily absorbs high radial forces. Thanks to the two fixed flanges on the outer ring and the single-sided flange on the inner ring, the component also transmits axial forces from one direction. The design allows for axial displacement in the opposite direction, which compensates for thermal expansion of shafts. Typical applications include shaft mountings with single-sided guidance and thermally induced dimensional changes.
What are the distinctive features of the NJ design with a polyamide cage?
The version with a polyamide cage guides the rolling elements elastically and contributes to quiet running. The inner ring can be removed from one side, which facilitates the separate assembly of the inner and outer rings. As this is an open bearing without an integrated seal, designers can flexibly tailor the lubrication and external sealing solution to the adjacent structure. The permissible temperature range is from -30 to +120 degrees.
What are the key features of the NJ2208 -E-XL-TVP2 cylindrical roller bearing?
The component is a single-row roller bearing with a support bearing function. The cylindrical rollers transmit high radial forces via line contact. A polyamide cage maintains a uniform spacing between the rolling elements. The removable inner ring makes it easy to fit the individual bearing rings into the housing and onto the shaft.
What are the dimensions of the NJ2208 cylindrical roller bearing?
The bearing has an internal diameter (bore) of 40 mm, an external diameter of 80 mm and a width across flats of 23 mm. These dimensions correspond to the standardised NJ2208 series. The outer ring is smooth and has no lubrication groove or bore.
What does the ‘NJ’ design designation mean for this bearing?
The NJ design has two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the bearing to support the shaft axially in one direction. In the opposite direction, the shaft remains free to move, thereby compensating for operational thermal expansion without causing harmful forced stresses.
What are the bearing clearance and tolerance class for this model?
This cylindrical roller bearing is manufactured with standard radial clearance. It complies with tolerance class P0 or PN, which corresponds to the international ABEC 1 classification. This precision grade meets the standard requirements for general mechanical engineering.
What is the permissible temperature range for the NJ2208 -E-XL-TVP2?
The permissible operating range is between -30 and +120 degrees Celsius. This range is determined by the material properties of the polyamide cage and the thermal stability of the bearing components. To ensure proper operation, a lubricant must be selected that covers this range.
Why is the bearing designed as an open model without a seal?
The open design without sealing washers allows for use in enclosed assemblies with an external lubricant supply. The lubricant can circulate and reach the contact zones. Protection against dust and moisture is provided by external seals on the connecting structure.
