Cylindrical Roller Bearings FAG NU214 -E-XL-TVP2
The FAG NU214 -E-XL-TVP2 single-row cylindrical roller bearing, measuring 70 × 125 × 24 mm, withstands high radial loads and serves as a flexible support bearing.
The NU214 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing of the NU design. Thanks to the line contact between the rollers and the raceway, this design can withstand high radial loads. FAG manufactures this model in tolerance class P0/PN or ABEC 1 with standard radial clearance. The open bearing has no integrated seal and can be supplied directly with lubricant via an external lubrication system. The outer ring is designed without a groove or lubrication bore.
What is the NU214 -E-XL-TVP2 cylindrical roller bearing suitable for in mechanical engineering?
The NU design is primarily used as a non-locating bearing for structures subject to high radial forces. Both guide flanges are located on the outer ring, whilst the flangeless inner ring remains freely axially movable on both sides. The bearing assembly thus directly compensates for changes in shaft length resulting from thermal expansion within the rolling element set. This prevents axial stress in the overall system and promotes low-friction operation.
What are the distinctive features of the TVP2 polyamide cage version?
The suffix TVP2 denotes a polyamide cage. This cage material operates quietly, is characterised by its low weight and dampens vibrations during operation. The permissible temperature range is between –30 and +120 degrees Celsius. As the inner ring can be removed from both sides, the inner and outer rings can be mounted separately on the shaft and housing. This simplifies installation and any maintenance work required.
What are the main dimensions of the NU214 -E-XL-TVP2 cylindrical roller bearing?
The dimensions are exactly 70 mm bore diameter, 125 mm outer diameter and 24 mm width. It is a single-row radial bearing without a groove or lubrication hole in the outer ring. The bearing is manufactured to standard tolerances in accordance with P0/PN or ABEC 1.
What does the NU design designation mean for this roller bearing?
In the NU design, the outer ring has two fixed guide flanges, whilst the inner ring has no flanges. This allows the inner ring to be withdrawn from either side. The bearing acts purely as a support bearing and absorbs radial forces, whilst compensating for axial shaft displacement without restriction.
What material is the TVP2 cage made of?
The suffix TVP2 denotes a polyamide cage. This material is characterised by its low weight and smooth, quiet running. The cage is designed for operating temperatures ranging from -30 to +120 degrees Celsius.
What type of lubrication does the open bearing require?
As the design does not incorporate integral sealing washers, lubrication is supplied via the housing or an external lubrication system. Depending on the operating conditions, the cylindrical roller bearing can be operated using lubricating oil or grease. An external seal protects against the ingress of dirt.
What is the clearance in the NU214 -E-XL-TVP2 cylindrical roller bearing?
This model features standard radial bearing clearance. This standard bearing clearance is suitable for the majority of industrial operating conditions with standard fit selections on the shaft and housing, provided that no extreme temperature differences arise between the inner and outer rings during operation.
How is the installation carried out with a removable inner ring?
The separable inner ring allows for separate assembly: the inner ring is fitted onto the shaft seat and the outer ring, together with the roller set and cage, is inserted into the housing. When the assemblies are joined, there is no risk of damaging the raceways due to misalignment or unfavourable axial forces.
