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.
