Cylindrical Roller Bearings FAG NU2220 -E-XL-TVP2

The FAG NU2220 -E-XL-TVP2 cylindrical roller bearing, with main dimensions of 100 × 180 × 46 mm, provides a robust floating support for heavy radial loads in mechanical engineering.

The FAG NU2220 -E-XL-TVP2 cylindrical roller bearing is designed as a single-row radial roller bearing to accommodate high radial forces. Thanks to the line contact between the cylindrical rollers and the raceways, this roller bearing can withstand high loads. The open design allows direct access to lubricant via the housing system. With a bore diameter of 100 mm, an outer diameter of 180 mm and a width of 46 mm, the unit is suitable for demanding shaft mountings in general mechanical engineering and plant construction.

What is the NU2220 -E-XL-TVP2 cylindrical roller bearing suitable for?

This design primarily accommodates forces where high radial loads are present and where changes in shaft length due to thermal expansion must be compensated for. As a floating bearing of the NU design, the bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the shaft to move axially relative to the housing without restriction. Typical applications are found primarily in shaft mountings subject to high radial loads.

What advantages does the TVP2 polyamide cage offer in this non-locating bearing?

The TVP2 polyamide cage is characterised by its low weight and elastic material properties. This reduces inertial forces during acceleration and dampens operating noise during operation. Designed for a temperature range of –30 to +120 degrees, the open bearing operates reliably with standard lubricating oils and greases. As the inner ring can be removed from both sides, the inner and outer rings can be fitted separately onto the shaft and housing.

What makes the NU2220 -E-XL-TVP2 cylindrical roller bearing stand out?

This single-row cylindrical roller bearing has a bore of 100 mm, an outside diameter of 180 mm and a width of 46 mm. As an open, non-locating bearing of the NU design, the outer ring guides the rollers via two fixed flanges, whilst the flangeless inner ring compensates for axial displacement of the shaft. A TVP2 polyamide cage ensures low-vibration guidance of the rolling elements.

What is the function of the NU design as a non-locating bearing?

The NU design accommodates radial loads only. As the inner ring has no flanges, it can be displaced axially in both directions relative to the roller set. Designs make specific use of this characteristic to absorb thermal linear expansion of shafts within the bearing without causing stress.

What is the clearance in this bearing design?

The bearing has the standard radial clearance (CN). This factory setting is sufficient for typical installation conditions with standard fits on the shaft and housing. The existing radial clearance ensures that, after the rings have been pressed in and subject to operational heating, perfect concentricity is maintained without any distortion.

What is the operating temperature range of the NU2220 -E-XL-TVP2 cylindrical roller bearing?

The permissible temperature range extends from -30 to +120 degrees Celsius. This range is essentially limited by the material of the TVP2 polyamide cage and the thermal resistance of the externally supplied lubricant. This makes the bearing design suitable for a wide variety of industrial operating environments with moderate heat generation.

How is the split bearing fitted?

The inner ring of the bearing can be removed from either side and fitted separately onto the shaft seat. Insert the outer ring, together with the roller set and cage, into the housing bore separately. This separate assembly simplifies handling in the case of larger fits and facilitates future maintenance and inspection work.

What are the lubrication requirements for the open version?

As the bearing is supplied without integrated sealing washers, an effective seal within the housing is required. Lubrication is provided by the circulating lubricant in the system, such as an oil bath or circulating lubrication. As the outer ring has no lubrication groove, the lubricant must be supplied from the side of the rolling elements.
