Cylindrical Roller Bearings FAG NUP313 -E-XL-TVP2
The FAG NUP313 -E-XL-TVP2 cylindrical roller bearing, measuring 65x140x33 mm, offers high radial load-carrying capacity and axial guidance on both sides when used as a fixed bearing.
The FAG NUP313 -E-XL-TVP2 cylindrical roller bearing, as a single-row rolling bearing, can accommodate very high radial loads. Due to its NUP design, the component is used in mechanical engineering as a classic fixed bearing, as fixed flanges on the outer ring and a fixed flange with a loose flange disc on the inner ring absorb axial forces in both directions. This version features a flexible polyamide cage and operates with standard radial clearance within a temperature range of -30 to +120 degrees.
What is the NUP313 -E-XL-TVP2 cylindrical roller bearing suitable for?
Designs subject to high radial forces whilst simultaneously requiring axial fixation of the shaft benefit from the NUP design. Common applications include industrial drives and mechanical shaft bearings subjected to combined loads. The combination of linear force transmission by the rollers and the flange guidance on both sides stabilises the supported shafts against axial displacement without the need to install a separate thrust bearing.
What advantages does the TVP2 polyamide cage offer in this design?
The designation TVP2 indicates a polyamide cage that precisely guides the cylindrical rollers. Compared with metal cages, the material offers the advantages of lower weight, good damping properties and smooth running. As this is an open bearing without an integrated seal, a clean installation environment with external housing sealing and a targeted lubricant supply is required to support operation at temperatures up to +120 degrees.
What are the distinctive features of the NUP design in the NUP313 -E-XL-TVP2 cylindrical roller bearing?
The NUP design features two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. As a result, this cylindrical roller bearing functions as a fixed bearing and, in addition to primarily high radial forces, also transmits axial guidance forces in both directions directly via the roller end faces.
What are the dimensions of the NUP313 -E-XL-TVP2 cylindrical roller bearing?
The single-row bearing has a bore diameter of 65 mm, an outside diameter of 140 mm and a width across flats of 33 mm. The dimensional and running tolerances comply with the standard tolerance class P0/PN or ABEC 1.
What does the suffix ‘TVP2’ mean in relation to the FAG bearing?
The suffix TVP2 indicates a polyamide cage. This material reduces the moving mass of the roller guide, operates with low vibration and offers good damping. It limits the permissible operating temperature range of the assembly to values between -30 and +120 degrees.
How is the NUP313 -E-XL-TVP2 open cylindrical roller bearing lubricated?
As the design is open and has no integrated sealing washers, the lubricant reaches the raceways and roller bodies directly. Depending on the design requirements, the bearing can be supplied with grease or lubricating oil via the housing environment, although external seals must prevent the ingress of dirt particles.
What does the specification of the standard radial bearing clearance mean for installation?
The standard radial bearing clearance corresponds to the manufacturer’s standard clearance between the rollers and raceways as supplied, in a state free from measurement forces. It is suitable for conventional fit designs and normal operating temperatures where no extreme thermal expansion between the shaft and housing needs to be compensated for.
