Cylindrical Roller Bearings FAG NUP222 -E-M1
The FAG NUP222 -E-M1 cylindrical roller bearing with dimensions of 110 x 200 x 38 mm can accommodate high radial loads and secures the shaft axially at both ends.
This single-row cylindrical roller bearing, the NUP222 -E-M1, is designed as an open, fixed bearing. The NUP design features two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. The bearing assembly withstands very high radial forces and also guides the shaft in both axial directions. FAG manufactures this model with a robust brass cage and standard radial clearance for demanding industrial drives.
For which load conditions is the NUP222 -E-M1 cylindrical roller bearing suitable?
The bearing is designed to fix shaft positions axially in the longitudinal direction under heavy radial loads. Designs featuring line contact between the rollers and raceways prove particularly effective when high transverse forces are present in the drivetrain. The integrated flanges and the loose flange disc transmit any guiding and supporting forces that arise axially in both directions.
What features does the NUP design with a brass cage offer?
The solid brass cage guides the cylindrical rolling elements precisely and is suitable for applications involving vibrations or acceleration forces. Manufacture to tolerance class P0 (standard tolerance or ABEC 1) facilitates a precise fit in standardised housing bores and on corresponding shaft seats. As the bearing is unsealed, it connects directly to the customer’s lubrication system and operates within a temperature range of -30 to +150 degrees.
What function does the NUP222 -E-M1 cylindrical roller bearing fulfil as a fixed bearing?
The NUP design features fixed flanges on the outer ring, as well as a fixed flange and a loose flange disc on the inner ring. Thanks to this geometry, the component primarily transmits heavy radial forces, whilst simultaneously accommodating axial guidance forces in both directions and securing the mounted shaft in its longitudinal position.
What are the main dimensions of this bearing unit?
The bearing has an internal diameter of 110 mm at the bore, an external diameter of 200 mm and a width across flats of 38 mm. These dimensions correspond to the standardised key dimensions for single-row cylindrical roller bearings and facilitate replacement during scheduled maintenance or new designs.
What are the advantages of the built-in brass cage?
The brass cage maintains a uniform spacing between the cylindrical rolling elements and withstands high inertial forces. It is suitable for industrial applications involving vibrations, shock loads or varying speeds, where simpler cage designs reach their mechanical load limits.
What is the operating temperature range of the bearing?
The permissible operating temperature for this model ranges from -30 to +150 degrees. This range is limited by the dimensional stability of the steel rings and the properties of the brass cage. For normal operation, it is essential that the lubricant used is suitably matched to this temperature range.
Why doesn’t the bearing have integrated seals?
As an open cylindrical roller bearing, the product is designed for systems with external housing seals and targeted lubricant supply. This allows for the continuous replacement of lubricating oil or targeted relubrication with grease whilst the bearing is in operation. At the same time, the open design minimises friction losses compared with sliding sealing elements.
What does tolerance class P0 mean in terms of installation?
Tolerance class P0 corresponds to the standard tolerance or ABEC 1 classification. It defines standardised limit dimensions for bore, outside and width dimensions, as well as concentricity. This enables the bearing to be reliably combined with appropriately matched fits for shafts and housing bores.
