The design of bearing and motor construction focuses on motor type,force on the motor,speed,lubricate type,including
bearing,design of oil sea and lubricant etc.It has the advantage of credible performance and easy maintenance.For the frame size
from 250 and below,we generally use closed bearing;frame size above 250 we use open type.Bearing.Regreasing can be done during
running.Perfect primer ensures the motors with good apperance and the motors are durable.We can also use special corrosion
protection coating.
