Cylindrical Roller Bearings FAG NU219 -E-M1
The FAG NU219 -E-M1 cylindrical roller bearing, with a 95 mm bore, offers high radial load-carrying capacity and axial displacement capability when used as a non-locating bearing.
This single-row NU219 -E-M1 cylindrical roller bearing from FAG is primarily designed to accommodate high radial forces. Thanks to the line contact between the rollers and raceways, the design can withstand high loads. As an open bearing without an integrated seal, the unit is designed for lubrication systems using oil or grease. The permissible temperature range extends from –30 to +150 degrees Celsius and covers demanding thermal conditions in mechanical engineering.
What is the NU219 -E-M1 cylindrical roller bearing used for?
The bearing unit absorbs high radial forces in rotating systems. As the inner ring is flangeless on both sides and therefore removable, the bearing functions purely as a non-locating bearing. It compensates for thermally induced changes in shaft length without constraint within the rolling elements. The outer ring has no lubrication groove or bore, so lubricant is supplied via the housing design or the open end face.
What advantages do the brass cage and NU design offer during assembly?
The brass cage guides the rolling elements precisely and withstands mechanical stresses and vibrations. The standard radial bearing clearance contributes to stable running behaviour under normal operating conditions. Thanks to tolerance class P0/PN (corresponding to ABEC 1), the bearing meets common industry standards. The separate assembly of the inner and outer rings facilitates press-fitting and installation into the bearing housing.
What are the dimensions of the NU219 -E-M1 cylindrical roller bearing?
With a bore of 95 mm, an external diameter of 170 mm and a width of 32 mm, these key dimensions define the installation space on the shaft and within the bearing housing. It is advisable to check the fit of both bearing rings before assembly.
What are the distinctive features of the NU design in cylindrical roller bearings?
In the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless. This allows the inner ring to be removed axially from either side. The bearing acts purely as a support bearing, compensating for thermally induced changes in the length of the shaft within the roller guide.
What are the characteristics of this bearing’s brass cage?
The brass cage is characterised by high strength and good run-on performance. It guides the cylindrical rollers precisely along the raceways, even at varying speeds or in the presence of vibrations. This ensures stable operation under demanding industrial conditions.
What is the permissible temperature range for the NU219 -E-M1 cylindrical roller bearing?
The permissible operating temperature range is from -30 to +150 degrees Celsius. Within this range, the bearing rings and the brass cage retain their dimensional stability. When selecting the lubricant, the actual operating temperature at the bearing location should be taken into account.
How is the open bearing lubricated and sealed?
As an open bearing without integrated seals, the bearing housing requires external sealing via the casing. The rolling bearing can be operated using either grease or lubricating oil. The casing seal prevents lubricant loss and protects the raceways from ingress of dirt.
What does ‘normal radial bearing clearance’ mean for this roller bearing?
Normal radial bearing clearance refers to the standard radial clearance between the rollers and raceways when the bearing is unmounted. This clearance ensures that, after the bearing has been pressed onto the shaft and fitted into the housing, there remains sufficient operating clearance to allow for low-friction rotation.
