Cylindrical Roller Bearings FAG NU220 -E-M1
The FAG NU220 -E-M1 cylindrical roller bearing, measuring 100 × 180 × 34 mm, can withstand high radial loads and serves as a separable idler bearing.
The FAG NU220 -E-M1 cylindrical roller bearing is a single-row rolling bearing designed for demanding industrial applications. With a bore of 100 mm, an outer diameter of 180 mm and a width of 34 mm, this design can withstand high radial forces. Thanks to its open design without an integrated seal, the bearing can be flexibly integrated into existing lubrication systems. The brass cage guides the cylindrical rollers securely and enables operation within a temperature range of -30 to +150 degrees.
What is the NU220 -E-M1 cylindrical roller bearing suitable for?
The NU220 -E-M1 cylindrical roller bearing is primarily used in bearing arrangements where high radial forces are present and changes in shaft length need to be compensated for. As a floating bearing of the NU design, the bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides and moved axially. This design is suitable for applications in general mechanical engineering that require reliable guidance under high radial loads.
What role do the brass cage and design play in the selection process?
When designing the bearing mounting, the combination of design and cage material determines suitability. The solid brass cage of type -M1 is designed for high vibrations and acceleration forces. Together with tolerance class P0 or ABEC 1 and standard radial clearance, this variant covers a wide range of installation scenarios. As the outer ring is manufactured without a groove or lubrication bore, this open cylindrical roller bearing requires external sealing and a lubricant supply.
What are the dimensions of the NU220 -E-M1 cylindrical roller bearing?
This bearing has a bore of 100 mm, an outer diameter of 180 mm and a width of 34 mm. It complies with tolerance class P0 or ABEC 1 and is designed as a single-row cylindrical roller bearing. The mounting dimensions of the shaft and the housing should be precisely matched to these dimensions.
What does the NU design designation mean for this cylindrical roller bearing?
The NU design denotes a non-locating bearing with two fixed flanges on the outer ring and a flangeless inner ring. The inner ring can be removed from either side, which simplifies the fitting of the rings onto the shaft and housing. During operation, the bearing compensates for axial displacement of the shaft relative to the housing without any constraint.
What features does the brass cage -M1 offer?
The suffix M1 denotes a solid brass cage that guides the rollers. Brass is characterised by its strength, low wear and resistance to vibration. This makes this type of cage particularly suitable for dynamic loads, varying speeds and demanding operating conditions in industrial drives.
How is the NU220 -E-M1 open cylindrical roller bearing lubricated?
As an open bearing, the NU220 -E-M1 has no integrated sealing washers. Furthermore, the outer ring has no lubrication groove or lubrication bore. Grease or oil must therefore be supplied via the surrounding housing structure, which also provides protection against dirt and moisture.
What is the temperature range for which the cylindrical roller bearing is designed?
The bearing is designed for an operating temperature range of -30 to +150 degrees. The version with standard radial bearing clearance provides the correct operating clearance at typical operating temperatures and fit conditions. When selecting a lubricant, care must be taken to ensure that the chosen lubricant is approved for the same temperature range.
Can the NU220 cylindrical roller bearing accommodate axial forces?
As a purely floating bearing, the NU design cannot transmit axial forces. The cylindrical rollers run on the flat raceway of the flangeless inner ring, allowing the shaft to move axially without restriction. A separate fixed bearing or support bearing is required in the bearing arrangement to accommodate axial forces.
