Mainstream of bearing types

For bearing types,self-aligning roller bearing and tapered roller bearing is the mainstream, but most of the use of self-aligning roller bearings in the non linear favorable. Non linear spindle generally need to consider the plus or minus 0.5 degrees.
As B type automatic self-aligning roller bearing  is designed by the use of the middle block side guide roller , it is no skew of the maximum load wide in the minimum load to load region , which can run in a stable torque and low fever cases.
In addition,vibration of blade and gear box vibration increasing of the rotor shaft bearing, there is danger of corrosion and friction .Therefore, optimal bearing selection and clearance and mating and selection of suitable oil is very important.
