Cylindrical Roller Bearings FAG NU313 -E-XL-TVP2
The FAG NU313 -E-XL-TVP2 cylindrical roller bearing, measuring 65x140x33 mm, offers high radial load capacity and serves as an easy-to-fit idler bearing.
The FAG NU313 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing designed for high radial loads. Manufactured in the NU design, this open bearing enables low-friction axial compensation of thermal length changes directly within the bearing housing. With key dimensions of a 65 mm bore, 140 mm outside diameter and 33 mm width, this design is suitable for demanding shaft mountings in general mechanical engineering and gearbox construction.
What is the NU313 -E-XL-TVP2 cylindrical roller bearing suitable for?
The NU313 -E-XL-TVP2 cylindrical roller bearing is particularly suitable for bearing arrangements subject to purely radial loads, where axial length changes in the shaft need to be compensated for. As the flangeless inner ring can be removed from both sides, the bearing compensates for axial displacement without inducing stress. In combination with a fixed bearing on the opposite side, it provides stable support for rotating shafts at high speeds.
What are the functions of the TVP2 polyamide cage and the NU design?
The designation TVP2 refers to a polyamide cage which offers the advantages of low weight and elastic guidance of the cylindrical rollers. This material absorbs shocks during operation and retains its dimensional stability within a temperature range of -30 to +120 degrees. As this is an open bearing without an integrated seal, users can specifically tailor the lubricant and external sealing within the housing to the respective environmental conditions. The P0/PN tolerance class offers standardised mounting dimensions.
What is the function of the NU design in the NU313 -E-XL-TVP2 cylindrical roller bearing?
The NU design features two fixed flanges on the outer ring, whilst the inner ring has no flanges. This allows the inner ring to be pulled out axially from either side. The bearing acts purely as a non-locating bearing, compensating for thermal linear expansion of the shaft with low friction internally, without absorbing any axial forces.
What are the dimensions of the NU313 -E-XL-TVP2 cylindrical roller bearing?
This single-row cylindrical roller bearing has a bore of 65 mm, an outer diameter of 140 mm and a width of 33 mm. It is manufactured to the standard tolerance classes P0 or PN and ABEC 1, which ensures a precise fit on standardised shafts and housing bores.
What does the suffix ‘TVP2’ mean in relation to this FAG bearing?
The designation TVP2 denotes a solid polyamide cage. This cage material is characterised by its low weight, elastic guidance of the rolling elements and good emergency running properties. It guides the cylindrical rollers quietly and is suitable for operating temperatures between -30 and +120 degrees.
How is the NU313 open cylindrical roller bearing lubricated and sealed?
The bearing has no integrated sealing washers, which allows grease or lubricating oil to reach the raceways and rollers unimpeded. The outer ring is designed without a lubrication bore. Lubricant is supplied via the housing cavity, whilst external housing seals, such as shaft seals, prevent the ingress of dirt.
What does the standard radial bearing clearance indicate for this bearing?
The standard radial bearing clearance refers to the internal radial clearance between the cylindrical rollers and the raceways prior to installation. This clearance helps to ensure that the correct operating clearance is established once the bearing rings have been pressed into place and the bearing has warmed up during operation. It is suitable for standard fits within normal operating ranges.
Can the inner ring be fitted separately during assembly?
The inner ring is fully removable and can be fitted onto the shaft separately from the outer ring and its roller cage. This feature simplifies installation in mechanical engineering, as both assemblies can be fitted separately and then aligned axially.
