Cylindrical Roller Bearings FAG NU2212 -E-XL-TVP2
The FAG NU2212 -E-XL-TVP2 cylindrical roller bearing, measuring 60x110x28 mm, withstands high radial loads and functions as a separable idler bearing.
The FAG NU2212 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing designed specifically for heavy radial loads. Thanks to the line contact between the cylindrical rollers and the raceways, this design offers high rigidity. The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the bearing to compensate for axial length changes in the shaft directly within the bearing with low friction.
When is the NU2212 -E-XL-TVP2 cylindrical roller bearing suitable as a floating bearing?
This radial roller bearing is particularly suitable for bearing arrangements where thermal linear expansion of the shaft occurs. As the inner ring has no flanges, it can slide on both sides and thus functions purely as a floating bearing. Typical applications include industrial shaft mountings where precise radial guidance under load is required, whilst axial fixation is provided by a separate fixed bearing.
What characteristics does the TVP2 polyamide cage offer in operation?
The suffix TVP2 denotes a polyamide cage that guides the rollers. The material reduces the weight of the rolling element set, ensures quiet running and is characterised by favourable running characteristics in the event of a temporary lack of lubricant. As this is an open bearing without an integrated seal, external sealing of the bearing housing is required. The bearing is designed for operating temperatures ranging from -30 to +120 degrees.
What makes the NU2212 -E-XL-TVP2 cylindrical roller bearing stand out?
This single-row roller bearing has solid flanges on the outer ring and a flangeless inner ring. Thanks to this design, it accommodates radial forces only, whilst axial movements of the shaft are compensated for without restriction. The integrated polyamide cage also ensures flexible roller guidance whilst keeping the weight low.
What are the dimensions of the NU2212 -E-XL-TVP2 cylindrical roller bearing?
The main dimensions are a bore diameter of 60 mm, an outside diameter of 110 mm and a total width of 28 mm. The bearing is manufactured to the standard tolerance class P0/PN or ABEC 1.
What does the NU design designation mean for this bearing?
In the NU design, the outer ring guides the rollers between two fixed flanges, whilst the inner ring has no flanges. The inner ring can therefore be removed completely from either side. This simplifies assembly, as the outer ring and inner ring can be pressed in separately.
What is the bearing clearance for this model?
The bearing is manufactured with standard radial bearing clearance. The bearing clearance describes the radial play of the rollers when the bearing is unloaded. It is dimensioned such that, under normal mounting conditions and at typical operating temperatures, reliable concentricity is achieved without any impermissible preload.
Within what temperature range can the bearing be operated?
The permissible temperature range is from -30 to +120 degrees. The upper temperature limit is primarily determined by the TVP2 polyamide cage, which remains dimensionally stable and wear-resistant within this range. The lubricant selected must be suitable for this operating range.
Is the bearing sealed or lubricated?
This is an open cylindrical roller bearing without sealing washers. During installation, the bearing must be lubricated via the housing using a suitable grease or via an oil circulation system. Additional external seals, such as shaft seals, protect the open interior from dirt and moisture.
