The limit of the thin wall bearings contact Angle

The limit of the thin wall bearings contact Angle is 120 °. When the sliding bearing wear and tear to the contact Angle, fluid lubrication will be destroyed. So don't affect the sliding bearing compressive conditions under the premise of the smaller the contact Angle is better. From the theoretical analysis of the friction torque, when the contact Angle is 60 °, minimum friction torque, so, the speed is higher than 500 r/min of miniature linear bearings, contact Angle 60 °, speed is less than 500 r/min of sliding bearing, contact Angle can be used in a 90 °, 60 ° is used.

Shaft neck and the actual situation of the sliding bearing surface contact, available per unit area of the actual contact points. The more contact, more and more even, said sliding bearing scraping the research better, on the other hand, sliding bearing scraping the inquiry is not good. In general the more the more close contact point, research difficulty is large. Production should be based on the performance of the sliding bearing and working conditions to determine the contact point
