NU311M Cylindrical Roller Bearings

NU311M Cylindrical Roller Bearing and Removable Inner Ring, this is a popular size that could be used in many application that uses this size 55mm x 120mm x 29mm. Bearing is made of Chrome Steel.

 

Cylindrical roller bearing:

Cylindrical roller bearings are one kind of separable bearing, its inner ring and outer ring & roller are linear contact, friction coefficient smaller, suitable for high-speed rotation, and also can suffer larger axial load, this kind of bearing mainly apply in electricity motor, gear shaft and machine tools. It have single row, double row, four row even six row rollers' type. 
        

 

Cylindrical roller bearing features:

                                                    
1.Roller and groove for line contact or repairing referral contact, radial load capacity, applicable to withstand heavy load and impact load.
2.Small friction coefficient,suitable for high speed limits,to deep groove ball bearings.
 
3.installation error caused by the relative position of the shaft and the shell, can make use of the supporting free.
 
4.For shaft or block hole machining the demand is higher,after installation invading.this bearing relative to strict control axis deflection,
 
5.Ring in separable,convenient in installation and removal.
 
6.Main purpose:Large motor vehicles,motorcycles,spindle,internal-combustion engine,generator,

gas turbines and reducer,rolling mill,the vibration
