Product Specifications:
Cylindrical roller and race for line contact bearing. Load capacity is big, mainly bear radial load .
1. Friction coefficient is small, suitable for high speed limit speed close to deep groove ball bearings
2.N and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing
3. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contactstress concentration

Types of cylindrical roller bearing
1. N Series - Bearings of N design are single row cylindrical roller bearing and have two fixed ribs on the inner ring that retain the rollers and cage and one smooth outer ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, N Series rolling bearings are used in non-locating bearing units. Also, the N Series bearings have virtually no thrust capacity
2. NU Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and one smooth inner ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, NU Series rolling bearings are used in non-locating bearing units. Also, the NU Series bearings have no virtually thrust capacity.
3. NJ Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and a fixed rib on the inner ring which can guide the shaft in a single direction (axially).
4.NUP Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and, on the inner ring, a fixed rib and a support washer. This way they can be used as locating bearings, guiding the shaft axially in both directions.
5.RNU Series - Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and has no inner ring. Instead, it uses the shaft as the opposing raceway
6. NF Series - Also able to carry incidental thrust loads, this bearing type features two integral ribs on the inner ring and a single rib on the outer ring.
7.NN Series - Bearings of NN design are double row cylindrical roller bearing and have three fixed ribs on the inner ring that retain the rollers and cage and one smooth outer ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, N Series rolling bearings are used in non-locating bearing units. Also, the NN Series bearings have no virtually thrust capacity.
8.NNU Series - Are double row cylindrical roller bearings and have three fixed ribs on the outer ring and one smooth inner ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, NU Series rolling bearings are used in non-locating bearing units. Also, the NNU Series bearings have no virtually thrust capacity.

- Full cylindrical roller bearingCommon cylindrical roller bearings1, single row full cylindrical roller bearingsNCFNJG2 、 double row full cylindrical roller bearingNNCLNNCFNNCNNFTwo, not common full cylindrical roller bearings1, full spherical cylindrical roller bearings2, CARB ring roller bearings
- Q: Is the roller bearing and the bearing chamber movable in the tapered rotor motor?
- E in cylindrical roller bearing is the meaning of improving internal cage design, similar to the SKF cylindrical roller bearing EC form, this type of bearing than without E, is to strengthen the design, the roller is filled more larger to increase the load. From the load point of view, it is better to choose E.
- Q: What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
- The convex roller refers to the basic cylindrical or conical roller with a continuous micro convex radian in the plane containing the roller axis, and the logarithmic curve roller is also a convex roller, which belongs to a full convex roller;Convexity roller refers to the plane containing the axis of roller in the outer surface of a continuous convex curved basic cylindrical or conical roller, roller is logarithmic curve convexity roller, roller is all convex; convexity roller refers to the plane containing the axis of roller in the outer surface of a continuous convex curved basic cylinder or conical roller,The logarithmic curve roller is also a convex roller, which belongs to a full convex roller; a modified roller refers to a roller that has a slightly modified diameter at the end of the outer surface to prevent the contact between the roller and the raceway.

- Q: Is the nu240em cylindrical roller bearing split?
- Therefore, such bearings need to be installed in the axial load bearing the main components, only at the same time using other types of bearings to withstand axial load on the premise that can be used.
- Q: The Russian bearing suffix No. ZST is a cylindrical roller bearing
- The suffix code is not used to distinguish the bearings, but it helps to explain the structure of the bearings and the material.
