Advantages and disadvantages with the rolling bearing and how to choose
 

Rolling generally use chromium bearing steel, wear and heat resistance, the rolling bearing part of the friction with the contact surface is small, but generally can not afford to shock loading.

The main body of the bush bearing, power transfer equipment used in large-scale sliding bearings, usually made of bearing with Babbitt, the softening point, melting points are lower, slide bearingwith the axis of the contact area, bearing load, shock absorption Well, can withstand the shock load, if the oil stored in the lower part of the bad drive when the need for oil to ensure that tile surface film formation. General bearing temperature does not exceed 80 ℃, bearing temperature does not exceed 70 ℃.
