Single row cylindrical roller bearings
N, NU type
The outer ring of type N bearing has no guard edge, while the inner ring has a guarded edge on both sides. The displacement of the shaft relative to the bearing seat in both axial directions can be allowed. The outer ring of the bearing of the NU type has guard edges on both sides, while the inner ring has no guard edges. It is also possible to allow displacements between shafts relative to bearings in both axial directions.Therefore, this kind of structure is suitable for swimming end bearing.
NJ, NF type
The outer ring of NJ type bearing has a block edge on both sides, while the inner ring has a block edge on one side.It can withstand a certain amount of unidirectional axial load. The outer ring of the NF type has a block on one side and the inner ring has a block on both sides.It can also bear a certain amount of unidirectional axial load. Therefore, this kind of structure is suitable for single - direction axial bearing.
NUP, NFP
The NUP type bearing has two sides of the outer ring, one side of the inner ring has a single side (fixed), and the other side is a separable flat ring. Can withstand a certain amount of two-way axial load.
The NFP type bearing outer ring has a single fender (fixed) on one side, and a separable flat-fender on the other, with fenders on both sides of the inner ring. It can also bear a certain amount of two-way axial load. This type of structural bearing can limit the displacement of the shaft relative to the bearing seat in both axial directions. Therefore, it is suitable for use as a fixed end bearing.
NH (NJ+HJ) type
NH bearing is the structure of the combination of NJ bearing and HJ oblique baffle ring. Because the inner ring of NUP type bearing is shorter, and the plain stop ring is not fixed, it is not convenient to use, while NH type bearing can use the width of the entire inner ring of NJ type bearing to keep a closer fit with the shaft. And NH bearing in the installation and disassembly more convenient.
The NH bearing can limit the axial displacement of the shaft relative to the bearing seat in both directions.Therefore, it is suitable for use as a fixed end bearing.
