Cylindrical Roller Bearing NFP Series
Bearings of type NFP have one flange, a loose flange on outer ring, and two integral flanges on inner ring. This type of bearing also can carry a certain amount of axial loads in double directions. This type of bearing can limit the displacement in double directions of the housing relative to the shaft. Therefore, they are suitable to be used as a locating bearing.
Most cages for single row NFP series cylindrical roller bearings are pressed steel cages or machined brass cages. While based on different bearing working conditions and client’s requirements, cages with other material and structure could be supplied, e.g.glass fiber reinforced polyamide, which can works continuously at the maximum temperature +120℃.
Single row NFP cylindrical roller bearings normally have cylindrical inner holes. But for some parts of the dimensions and specifications, tapered holes can also be provide. In this case, K would be added behind the bearing type.
Application
The cylindrical roller bearings are generally used on pumps, blowers, speed reducers, general machinery, large and medium-sized motor, locomotives, spindle, internal combustion engines, generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery.
