Cylindrical Roller Bearings FAG NU2305 -E-XL-TVP2-C3
The FAG NU2305 -E-XL-TVP2-C3 cylindrical roller bearing with dimensions of 25x62x24 mm is designed to withstand high radial loads and is used as a sliding support bearing.
The NU2305 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for high radial loads. The NU design is characterised by two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which facilitates the separate installation of both bearing rings. The open design requires a lubricant supply via the surrounding housing.
What function does the NU2305 -E-XL-TVP2-C3 cylindrical roller bearing fulfil as a non-locating bearing?
This roller bearing is primarily used as a conventional non-locating bearing. As the rollers can slide axially on the flangeless inner ring raceway, the NU2305 -E-XL-TVP2-C3 cylindrical roller bearing compensates for thermal length changes in shafts without constraint. Shaft bearings subject to thermal influences make specific use of this property to prevent axial stress in the bearing system. The NU design is not intended to accommodate axial forces.
What do the C3 clearance and the TVP2 polyamide cage mean for this bearing?
The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This increased clearance prevents the rolling elements from jamming when tight fits or temperature differences between the inner and outer rings reduce the radial clearance during operation. The suffix TVP2 denotes a solid window cage made of polyamide, which guides the cylindrical rollers. The permissible temperature range is from –30 to +120 degrees Celsius.
What are the distinctive features of the NU design in the NU2305 -E-XL-TVP2-C3 cylindrical roller bearing?
The NU design features two fixed flanges on the outer ring and a flangeless inner ring. This allows the inner ring to be withdrawn from both ends. This separability facilitates separate installation onto the shaft and housing. During operation, the bearing allows for unimpeded axial movement of the shaft relative to the housing.
What are the dimensions of the NU2305 -E-XL-TVP2-C3 cylindrical roller bearing?
This roller bearing has an inside diameter of 25 mm, an outside diameter of 62 mm and a width of 24 mm. It is manufactured to tolerance class P0, or standard tolerance (PN, ABEC 1). The outer ring is designed without a lubrication groove or lubrication holes.
What are the benefits of bearing clearance class C3?
A C3 bearing clearance indicates a greater radial operating clearance than that of the standard tolerance. This is advantageous in the case of tight fits on the shaft and housing seat, or when the shaft heats up during operation. The increased bearing clearance helps to ensure that the bearing runs without harmful stress, even under thermal expansion.
What does the abbreviation TVP2 mean in relation to the cage?
The suffix TVP2 denotes a solid polyamide window cage. This material is lightweight and ensures quiet operation of the roller bearings. It is suitable for operating temperatures ranging from -30 to +120 degrees Celsius, but requires compatibility with the lubricant used.
Is the bearing sealed and pre-lubricated?
No, it is an open bearing without integrated sealing washers. It is not pre-lubricated and must be continuously lubricated within the housing using grease or oil. Protection against dirt and moisture is provided by the surrounding housing structure.
Can the bearing accommodate axial forces?
No, the bearing is used exclusively as a floating bearing for transmitting radial forces. As the inner ring has no flange, the cylindrical rollers can slide axially along the raceway, meaning that axial forces are not supported. For axial loads, the bearing arrangement must be supplemented by a separate fixed bearing.
