Product name	NSK Brand Factory Price NU 252 EM Cylindrical Roller Bearing
bearing materials	steel
Quality Certificate	ISO9001:2000
Row	Single Row
Application	Large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction boxes, rolling mills, vibrating screens and lifting and transportation machinery, etc.

Characteristics: 

1.Roller and raceway are in line contact or downline contact, radial bearing capacity is large, suitable for bearing heavy load and impact load.  
2.Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.  
3.N type and NU type can be moved in axial direction, can adapt to the change of the relative position between the shaft and the shell caused by thermal expansion or installation error, can be used as free end support.  
4.The processing requirements for shafts or seat holes are high. After bearing installation, the relative deviation of the outer ring axis should be strictly controlled to avoid contact stress concentration.  
5.The inner ring or outer ring can be separated, easy to install and disassemble.
