Single row cylindrical roller bearings

Single row cylindrical roller bearings

Type N, NU Bearings of type N have two integral flanges on inner ring and a flangeless outer ring. This type of bearings permits axial displacement in double directions of the housing relative to the shaft. The bearings of type NU have two integral flanges on outer ring and a flangeless inner ring. This type of bearings permits axial displacement in double directions of the housing relative to the shaft. Type NJ, NF Bearings of type NJ have two integral flanges one on the outer ring, and one on the inner ring. This type of bearing can carry a certain amount of axial load in a single direction. Bearings of type NF have one flange on the outer ring, and two integral flanges on the inner ring. This type of bearing can carry a certain amount of axial load in a single direction. Therefore, they are suitable to be used as an axial location bearing in single direction.. Type NUP, NFP Bearings of type NUP have two integral flanges on outer ring, one flange and separable loose flange on inner ring. This type of bearing can carry a certain amount of axial loads in double directions. 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. Type NH (NJ+HJ) Bearings of type NH are combined by the bearing of type NJ and the bearing of type HJ with catercornered flange. Comparing to NUP type with short flange ring and non-locating loose flange, type NH can take the advantage of the whole inner ring width of NJ to match with axes tightly. Moreover, it's quite convenient to mount and dismount. This type of bearings can limit axial displacement in double directions of the housing relative to the shaft. Therefore, they are suitable to be used as a locating bearing.
