N, NU type

The outer ring of the n-type SKF single row cylindrical roller bearing http://www.alierbearings.com/index.php?c=product&a=search&word=SKF+NU has no edge.

The displacement of the axial bearing between the axial bearing can be allowed.

The bearing outer ring of the "NU" type has the edge of the outer rim.

It is also possible to allow the axial displacement of the axial bearing between the axial positions.

Therefore, this kind of structure is suitable for use as a moving end bearing.

NJ, NF type

NJ type SKF single row cylindrical roller bearing outer ring with side edge, inner ring side with side.

Can withstand a certain amount of unidirectional axial load.

The outer ring of the NF type has the edge of the side, and the inner circle has the edge.

It can also withstand a certain amount of unidirectional axial load.

Therefore, the structure of this class is suitable for axial bearing used as a single direction.

NUP, NFP type

The NUP type SKF single row cylindrical roller bearing is on both sides of the outer ring with a side edge, the inner ring side band (fixed) one side, while the other side is a separable flat retaining ring.

It can withstand a certain amount of two-way axial load.

NFP type bearing outer ring side band (fixed) single edge, while the other side is a separable flat retaining ring with a side edge on both sides of the inner ring.

It can also bear a certain amount of two-way axial load.

The bearing of this kind of structure can limit the axial displacement of the axial bearing position on the axial direction.

Therefore, suitable for use as fixed end bearing.

NJ+HJ

The NH type bearing is the structure of the NJ type bearing and the hj-type slant retaining ring.

Due to the NUP type bearing inner ring is shorter, and flat collar is not fixed, use inconvenient, and NH type bearing type can make use of NJ bearing the entire inner ring width, keep closer cooperation with shaft.
