Single Row Cylindrical Roller Bearing NSK NJ205EM 25×52×15mm For Oil Fields Pumps

 

Cylindrical roller bearing NSK NJ205EM Bearing is one kind of rolling bearing, it consist of Inner Ring , outer ring ,cage and steel rollers, the cylindrical roller and raceway of the rings are line contact, so cylindrical roller bearings NSK NJ205EM Bearing are the same with spherical roller bearing, tapered roller bearing, thrust roller bearing and the other kinds of roller bearings, they all have larger load capacity than ball bearings, cylindrical roller bearing mainly carry radial load , Small friction between the rollers and the ribs of the rings make the cylindrical roller bearings NSK NJ205EM Bearing are suitable for the application which are high speed rotation. There are many different design according to the ribs of the rings , NU , NJ, NUP , N , NF series single row cylindrical roller bearing , NNU , NN series double row cylindrical roller bearing .

 

Cylindrical Roller Bearings also have the other different design as follows

-- Single Row Cylindrical Roller Bearings

-- Double Row Cylindrical Roller Bearings

-- High Capacity Cylindrical Roller Bearings

-- Single Row Full Complement Cylindrical Roller Bearings

-- Double Row Full Complement Cylindrical Roller Bearings

 

And different types of cylindrical roller bearings also have their different design according to their feather,and also many kinds of cages,just like Brass cage,Pressed Steel cage,nylon cage etc.

Feature of NSK NJ205EM Bearing

  1. The rollers and raceway of inner ring and outer ring are in line contact or repair line contact , this design can make the bearing have large carry capacity . So Cylindrical roller bearing are suitable for heavy load and impact load.
  2. Low friction coefficient, suitable for high speed, its limited speed are closed to deep groove ball bearing.
  3. N and NU series Cylindrical roller bearing can move in axial direction, so they can accommodate to the changes in the relative position of the shaft and the housing due to thermal expansion or mounting errors.
  4. High standard for the machining of shaft or seat holes , Relatively skew for the axial of the outer ring should be control strictly. So the Contact stress concentration can be avoid.
  5. The outer ring and inner ring of Cylindrical Roller Bearing are separatable , the design are easy installation and removal.
