Cylindrical Roller Bearings FAG NUP308 -E-XL-TVP2
The FAG NUP308 -E-XL-TVP2 cylindrical roller bearing is used as a fixed bearing on shafts with a 40 mm bore and can accommodate high radial loads.
The NUP308 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing for industrial applications involving demanding radial loads. With main dimensions of 40 mm inner diameter and 90 mm outer diameter, and a width of 23 mm, this design is suitable for standardised bearing seats. The manufacturer, FAG, produces this open bearing in the standard tolerance class P0/PN or ABEC 1, and with standard radial clearance for normal operating temperatures.
What is the NUP308 -E-XL-TVP2 cylindrical roller bearing suitable for in operation?
This rolling bearing is suitable for bearing arrangements where high radial forces act within a defined installation space. Thanks to the NUP design, the unit functions as a fully-fledged fixed bearing. Two fixed flanges on the outer ring and one fixed flange with a loose flange disc on the inner ring guide the shaft axially in both directions. Its use is recommended in bearing arrangements where precise guidance is required under predominantly radial loads.
What are the advantages of the fixed bearing design with a polyamide cage?
The integrated polyamide cage guides the cylindrical rollers with low mass, which reduces friction and promotes quiet running. The bearing design is rated for a temperature range of –30 to +120 degrees. As this is an open bearing without a seal and without a lubrication bore in the outer ring, the lubricant is supplied via the housing. Users can tailor the lubrication method and any external seals specifically to the respective design.
What are the main dimensions of the NUP308 -E-XL-TVP2 cylindrical roller bearing?
This version has a bore of 40 mm, an outside diameter of 90 mm and a width of 23 mm. These standardised dimensions ensure a precise fit when installed in the corresponding bearing seats. The component is designed as a single-row roller bearing without an outer ring groove.
What characterises the NUP design in this bearing?
The designation NUP refers to a fixed bearing that provides axial guidance in both directions. The outer ring has two fixed guide flanges. On the inner ring, a fixed flange and a loose flange disc provide axial support for the roller sets, ensuring that the shaft remains axially positioned within the housing on both sides.
For which temperature range is the version with a polyamide cage suitable?
The permissible operating temperature range is between -30 and +120 degrees. The lightweight polyamide cage keeps the rolling elements spaced apart and helps ensure smooth running. Do not exceed the temperature limit of +120 degrees in order to maintain the thermal stability of the cage material.
What is the bearing clearance and tolerance class of the bearing?
The model features standard radial bearing clearance. It complies with the specifications of tolerance class P0/PN or ABEC 1. This classification covers standard tolerances in mechanical engineering where no increased bearing clearance is specified.
How is the NUP308 open cylindrical roller bearing lubricated?
As the bearing is designed as an open type without sealing washers, lubrication is provided by the surrounding structure. Depending on the speed and operating conditions, you can use either grease or oil. As the outer ring has no lubrication bore, the lubricant enters the bearing interior via the end faces.
Does this roller bearing have an integrated seal?
No, this is an open bearing with no built-in sealing elements. Dirt and moisture must therefore be kept out of the bearing housing by means of external seals, such as shaft seals or labyrinth systems. This gives you a free choice of sealing solution.
