Cylindrical Roller Bearings FAG NU2205 -E-M1
The FAG NU2205 -E-M1 cylindrical roller bearing is a single-row non-locating bearing with a brass cage, measuring 25 x 52 x 18 mm, designed for radial loads.
The NU2205 -E-M1 cylindrical roller bearing withstands high radial forces and guides the shaft within the housing. Thanks to its cylindrical rollers, this radial roller bearing provides line contact with the raceways, making it suitable for high loads. The FAG design complies with the standard tolerance class P0/PN or ABEC 1 and has a standard radial clearance.
How does the NU2205 -E-M1, as a non-locating bearing, compensate for axial displacement?
This rolling bearing functions purely as a non-locating bearing for purely radial loads. As the inner ring has no flanges and can be removed from either side, the bearing compensates for axial changes in shaft length directly within the bearing. Cylindrical roller bearings of this design are primarily used where thermally induced changes in shaft length need to be compensated for. As the bearing has an open design, it integrates directly into the lubrication circuit of the surrounding structure.
What are the advantages of the brass cage in the NU2205 -E-M1 cylindrical roller bearing?
The solid brass cage, designated M1, guides the rollers and withstands mechanical loads and vibrations. Brass exhibits favourable emergency running properties under demanding operating conditions. The bearing is designed for a temperature range of -30 to +150 degrees. During installation, it should be noted that the outer ring has no groove or lubrication bore, and lubrication must be supplied via the housing design.
What does the NU design designation mean in the case of the NU2205 -E-M1 cylindrical roller bearing?
The designation NU refers to a cylindrical roller bearing whose outer ring has two fixed flanges, whilst the inner ring is flangeless. This allows the inner ring to be withdrawn from either side. The bearing functions purely as a non-locating bearing and compensates for axial displacement between the shaft and the housing without restriction within the bearing.
What are the dimensions of the NU2205 -E-M1 cylindrical roller bearing?
The bearing has an internal diameter of 25 mm, an external diameter of 52 mm and a width of 18 mm. Before fitting, you should check the shaft seat and the housing bore against these nominal dimensions to ensure a precise fit.
What distinguishes the cage marked with the suffix M1?
The suffix M1 denotes a solid brass cage. Brass is characterised by high strength, dimensional stability and good resistance to vibrations. Furthermore, the material offers favourable friction properties, which contribute to the operational reliability of the roller guide under demanding operating conditions or when faced with higher thermal requirements.
What is the clearance in this cylindrical roller bearing?
The model is manufactured with standard radial bearing clearance. The bearing clearance describes the radial play of the rollers between the raceways when the bearing is unassembled. The standard version is suitable for typical fits on shafts and housings, as well as for applications without excessive temperature differences between the inner and outer rings.
What is the operating temperature range for this bearing?
The NU2205 -E-M1 cylindrical roller bearing is specified for an operating temperature range of -30 to +150 degrees. As this is an open bearing without integrated seals, the actual operating limit in practice is essentially determined by the thermal stability of the lubricant used.
Is the NU2205 -E-M1 cylindrical roller bearing sealed?
No, this model is an open bearing without integrated grinding or cover discs. This allows lubricants such as oil or grease to circulate freely. With this design, protection against the ingress of dirt and moisture must be provided by the surrounding housing structure, for example by means of shaft seals.
