Cylindrical Roller Bearings FAG NU2317 -E-M1
The FAG NU2317 -E-M1 cylindrical roller bearing, with dimensions of 85 × 180 × 60 mm, withstands heavy radial loads and serves as a separable support bearing.
The NU2317 -E-M1 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With a bore of 85 mm, an outer diameter of 180 mm and a width of 60 mm, this design can withstand high radial loads. It is manufactured to the standard tolerance class P0/PN (ABEC 1) and with standard radial clearance. Thanks to its solid brass cage, the bearing can withstand even severe vibrations and higher mechanical stresses during operation.
What is the NU2317 -E-M1 cylindrical roller bearing suitable for?
This cylindrical roller bearing is particularly suitable for bearing arrangements involving purely radial force transmission. In industrial drive assemblies, it serves as a non-locating bearing, as the NU design compensates for axial changes in shaft length with low friction within the bearing. With a permissible temperature range of –30 to +150 degrees, the bearing is suitable for thermally demanding operating conditions. A prerequisite for its use is an installation space protected from contamination.
What are the distinctive features of the NU 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 inner ring to be mounted on the shaft separately from the outer ring, which simplifies the assembly of larger assemblies. The guided brass cage ensures dimensional stability at varying speeds and higher accelerations. As this is an open bearing without an integrated seal, the lubricant is supplied via the surrounding housing.
What are the dimensions of the NU2317 -E-M1 cylindrical roller bearing?
The bearing has an inside diameter of 85 mm, an outside diameter of 180 mm and a width of 60 mm. With these dimensions, it is designed as a single-row roller bearing whose inner ring can be removed from both sides. The outer ring has no groove and no lubrication hole.
How does the floating arrangement work in the NU2317 cylindrical roller bearing?
In the NU type, the outer ring guides the rollers between two fixed flanges, whilst the raceway of the inner ring is cylindrical and smooth. This allows the shaft to move axially relative to the housing unimpeded when it expands due to heat. This helps to prevent harmful axial stresses in the overall bearing assembly.
What is the function of the brass cage in this bearing?
The brass cage separates the individual cylindrical rollers from one another and prevents them from coming into contact with each other during operation. Brass is characterised by its dimensional stability and resistance to vibration. This makes the M1 version suitable for demanding operating conditions, even under shock loads or at varying speeds.
Why does this cylindrical roller bearing not have a seal?
As an open roller bearing, this design is intended for installation in locations where external seals in the machine housing provide protection against dirt. The open bearing system is lubricated during operation via the plant’s lubrication circuit, for example through oil circulation or housing greasing.
What do the specifications for tolerance class and bearing clearance mean?
The bearing complies with tolerance class P0, i.e. standard tolerance in accordance with ISO standards and ABEC 1. It has a standard radial clearance (CN). This radial clearance between the rollers and raceways ensures jam-free operation at operating temperature when standard fit selections are used for the shaft and housing.
What is the operating temperature range of the NU2317-E-M1?
This cylindrical roller bearing is specified for an operating range of -30 to +150 degrees Celsius. The components retain their dimensional stability within this range. The lubricant used must be selected so that its temperature limits cover the ambient conditions of the specific application.
