High speed NTN cylindrical roller bearing NU205

High speed NTN cylindrical roller bearing NU205

Cylindrical roller bearings have no ribs on either the inner or outer ring, so the 

rings can move axially relative to each other. These can be used as free-end 

bearings. Cylindrical roller bearings, in which either the inner or outer rings has 

two ribs and the other ring has one, are capable of taking some axial load in one 

direction Double-row cylindrical roller bearings have high radial rigidity and are 

used primarily for precision machine tools.

 The Series of cylindrical roller bearings comprises:

1. Types NU, N, NNU, and NN are suitable as free-end bearings. 
2. Types NJ and NF can sustain limited axial loads in one direction.
3. Types NH and NUP can be used as fixed-end bearings.
4. NH-type cylindrical roller bearings consist of the NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars.
5. The inner ring loose rib of an NUPtype cylindrical roller bearing should be mounted so that the marked side is on the outside.
6. The RNU cylindrical roller bearing has an outer ring with double capped edges but does not come with inner ring. Such bearing is the NU cylindrical roller bearings without the inner ring 
7. The RN cylindrical roller bearing has an inner ring with double capped edge but does not come with outer ring.
