2. cylinder blocks boring machine bearing Cylindrical Roller Bearing NU209M Classification

 

We can produce all kinds of products with various special specifications, enabling us to accept the customerized orders. Our main range of cylindrical roller bearings comprises the basic types:

-	single row cylindrical roller bearings, mainly of the NU, NJ, NUP and N designs
-	double row cylindrical roller bearings, mainly of the NNU and NN designs
-	multi-row cylindrical roller bearings

The range of cylindrical roller bearings comprises the basic types

single row cylindrical roller bearings, caged, mainly of the NU, NJ, NUP and N designs (fig 1)

double row cylindrical roller bearings, caged, mainly of the NNU and NN designs (fig 2)

multi-row cylindrical roller bearings, caged

 

3.Applications

• Industrial Gearboxes
• Electric Motors
• Automotive Transmissions
• Pumps
• Compressors
• Industrial Fans
• Windmills
• Unbalanced Exciters
• Screw Compressor Applications such as Air Conditioning Systems

 

4. Cylindrical Roller Bearings are classified into the following types:

Types NU, N, NNU, and NN are suitable as free-end bearings. Types NJ and NF can sustain limited axial loads in one direction. Types NH and NUP can be used as fixed-end bearings.

NH-type cylindrical roller bearings consist of the NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars.

The inner ring loose rib of an NUP-type cylindrical roller bearing should be mounted so that the marked side is on the outside

• 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.
• 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.
• 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.
• 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.
