Cylindrical Roller Bearings FAG NU309 -E-XL-TVP2
The FAG NU309 -E-XL-TVP2 cylindrical roller bearing (45x100x25 mm) serves as a separable idler bearing for high radial loads in mechanical engineering.
The FAG NU309 -E-XL-TVP2 cylindrical roller bearing, as a single-row roller bearing, withstands high radial forces. With a bore of 45 mm, an outside diameter of 100 mm and a width of 25 mm, this design complies with standard mounting dimensions. The open design without an integrated seal allows for direct lubrication within the machine housing. Thanks to standard radial clearance and a manufactured tolerance class of P0/PN or ABEC 1, this bearing is suitable for precisely guided shafts in a wide range of industrial applications.
What is the NU309 -E-XL-TVP2 cylindrical roller bearing suitable for?
This cylindrical roller bearing is primarily suitable for mounting positions where high radial forces are present and thermal length changes in the shaft need to be compensated for. As the inner ring has no flanges and can be removed from both sides, the unit functions purely as a non-locating bearing. Typical applications include bearing arrangements where axial displacement must be accommodated freely within the bearing.
What are the distinctive features of the polyamide cage and the design?
The integrated polyamide cage guides the cylindrical rolling elements with minimal vibration and ensures smooth running with even load distribution. The NU design allows the inner ring and outer ring to be fitted separately, which facilitates maintenance and installation in confined housings. Designed for a temperature range of -30 to +120 degrees, this open roller bearing is suitable for demanding thermal operating conditions in continuous industrial operation.
What are the distinctive features of the NU design in the NU309 -E-XL-TVP2 cylindrical roller bearing?
This design is characterised by two solid flanges on the outer ring and a flangeless inner ring that can be removed from either side. As a result, the bearing functions purely as a non-locating bearing. It accommodates radial loads only and allows axial displacement of the shaft relative to the housing within certain limits, which counteracts axial stresses caused by thermal expansion.
What are the dimensions of the NU309 -E-XL-TVP2 cylindrical roller bearing?
With an internal diameter of 45 mm, an external diameter of 100 mm and a width of 25 mm, the design complies with standardised key dimensions. This allows the roller bearing to be fitted precisely into corresponding housing bores and onto suitable shaft seats. Manufacturing is carried out to tolerance class P0/PN or ABEC 1 to ensure precise concentricity.
What are the characteristics of this bearing’s polyamide cage?
A polyamide cage is characterised by its low weight and elastic properties. It guides the rollers quietly and reduces friction under dynamic loads. The material is designed for the bearing’s specified temperature range of -30 to +120 degrees and is suitable for standard industrial applications with continuous lubrication.
Why is it an open bearing without a seal?
Open cylindrical roller bearings do not have integrated cover plates or sealing discs, which means that lubricants such as oil or grease can reach the rolling elements and raceways unhindered. In this design, protection against dirt and moisture is provided by external seals in the surrounding housing structure. This also facilitates regular relubrication and inspection of the bearing location whilst the equipment is in operation.
What does the specification for the standard radial bearing clearance mean?
As the internal radial clearance between the rollers and raceways when the bearing is unassembled, this clearance ensures that the bearing rotates freely without seizing once the rings have been pressed on and the bearing has warmed up during operation. For applications with standard fits and average operating temperatures, this design offers the right balance between guidance and smooth running.
What is the temperature range within which the bearing can be used?
The permissible temperature range for the NU309 -E-XL-TVP2 cylindrical roller bearing is between -30 and +120 degrees. Within these limits, the dimensional stability of the bearing rings and the mechanical strength of the polyamide cage are maintained. It is crucial for safe operation that the lubricant used is selected to suit the ambient temperatures at the bearing location.
