Cylindrical Roller Bearings FAG NU318 -E-M1
The FAG NU318 -E-M1 cylindrical roller bearing (90x190x43 mm) serves as a robust idler bearing with a brass cage for high radial loads in industrial applications.
The single-row cylindrical roller bearing NU318 -E-M1 from FAG, as an open radial roller bearing, withstands high radial forces. With a bore of 90 mm, an outer diameter of 190 mm and a width of 43 mm, this roller bearing is suitable for use in demanding machine designs. The integrated brass cage guides the cylindrical rollers precisely and withstands severe vibrations. The bearing has standard radial clearance and operates within a temperature range of -30 to +150 degrees.
What is the NU318 -E-M1 cylindrical roller bearing suitable for?
This cylindrical roller bearing is used in applications where high radial loads occur at medium to high speeds. Typical applications include demanding shaft mountings in mechanical and plant engineering. As this is an open bearing without an integrated seal, an external housing seal provides protection against contamination. Furthermore, the design allows for targeted lubrication with oil or grease via the surrounding structure.
What is the function of the NU non-locating bearing design with a brass cage?
In the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless and removable from both sides. This allows the bearing to compensate for axial length changes in the shaft caused by thermal expansion without any constraint within the bearing. At the same time, the separable design simplifies the separate assembly of the inner and outer rings. The solid brass cage offers high dimensional stability under dynamic loads. With tolerance class P0/PN (ABEC 1), the component meets standard industrial requirements for dimensional accuracy and concentricity.
What are the key features of the NU318 -E-M1 cylindrical roller bearing?
As a single-row radial roller bearing, this design is characterised by a 90 mm cylindrical bore and a robust construction. The solid brass cage guides the rollers reliably and is suitable for demanding operating conditions. As the inner ring is designed to be removable from both sides, the component functions purely as a non-locating bearing.
What are the dimensions of the NU318 -E-M1 cylindrical roller bearing?
The roller bearing has an inside diameter of 90 mm, an outside diameter of 190 mm and a width of 43 mm. These key dimensions determine the required installation space on the shaft and within the bearing housing. Before installation, check that the bearing seats on the shaft and housing are dimensionally accurate.
Why is the NU design constructed as a non-locating bearing?
In the NU design, the rollers are guided by two fixed flanges on the outer ring, whilst the inner ring is flat. This allows the inner ring to move axially relative to the roller set. This design compensates for temperature-induced changes in the length of the rotating shaft during operation and prevents axial stress in the bearing system.
What are the characteristics of the brass cage?
The suffix M1 denotes a solid brass cage that guides the cylindrical rollers. Brass cages offer high mechanical strength and are resistant to vibrations and high acceleration forces. They are suitable for demanding industrial applications involving high operating loads.
What is the temperature range for which the bearing is designed?
The permissible temperature range is from -30 to +150 degrees Celsius. The dimensional stability of the bearing rings and the brass cage is maintained within these limits. When designing the bearing assembly, care must be taken to ensure that the selected lubricant is also approved for the operating temperatures encountered.
How is the open cylindrical roller bearing lubricated?
As the bearing is manufactured without its own seals, the housing design must prevent the ingress of dirt and moisture. Depending on the design and environmental conditions, lubrication is provided either by grease or via a closed oil circuit directly through the bearing housing.
