Cylindrical Roller Bearings FAG NU307 -E-XL-TVP2-C3
The NU307 -E-XL-TVP2-C3 cylindrical roller bearing from FAG Wälzlager can accommodate high radial loads with a 35 mm bore and allows for axial displacement.
The NU307 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing in a reinforced E-design with main dimensions of 35 x 80 x 21 mm. As a non-locating bearing of the NU design, it has 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 assembly of both bearing rings and compensates for changes in shaft length during operation.
In which applications does the NU307 -E-XL-TVP2-C3 cylindrical roller bearing excel?
This bearing unit is suitable for bearing locations where high radial forces act and thermal linear expansion of the shaft must be accommodated. Relevant areas of application include mechanical engineering and drive systems with high radial loads. Thanks to the line contact of the cylindrical rollers, the component offers high radial load-carrying capacity and rigidity.
What functions do the polyamide cage and the C3 bearing clearance fulfil in the NU307 -E-XL-TVP2-C3?
The polyamide cage (TVP2) guides the rollers with low friction and is characterised by its low weight. The increased radial clearance (C3) compensates for dimensional changes caused by tight fits on the shaft and housing or by operational heating. As the bearing is of an open design and contains no integrated lubricant, the grease or lubricating oil can be selected to suit the surrounding structure.
What are the dimensions of the NU307 -E-XL-TVP2-C3 cylindrical roller bearing?
With an internal diameter of 35 mm, an external diameter of 80 mm and a width of 21 mm, the bearing corresponds to the main dimensions of the NU307 series in tolerance class P0 or ABEC 1.
What does the NU design designation mean for this bearing?
The NU design is a non-locating bearing with two fixed flanges on the outer ring and a flangeless inner ring. As the inner ring can be removed from both sides, this allows for free axial movement of the shaft relative to the housing.
What are the key features of bearing air class C3?
Class C3 is characterised by increased radial bearing clearance compared with the standard version. This additional internal clearance compensates for fit allowances or temperature differences between the inner and outer rings during operation.
What are the features of the TVP2 cage?
As a polyamide window cage, the TVP2 model is characterised by quiet operation, vibration-damping properties and low inertia. The bearing is designed for a temperature range of -30 to +120 degrees Celsius.
How is the open cylindrical roller bearing lubricated?
As the bearing is designed as an open type without seals and without a groove or lubrication bore in the outer ring, lubrication is provided either via an external lubrication circuit using oil or by manually applying grease during assembly.
