Hi guys in this article we learn about the new topic we discussed the topic What are the basic Difference Between Sliding Contact and Rolling Contact Bearing   it is important topic in Theory of machine, in Mechanical Engineering so let's start without wasting of time,  

What are the Introductory Difference Between Sliding Contact and Rolling Contact Bearing

Rolling contact bearing refers to variety of bearings. Rolling contact bearing are advantage on cost, durability, size, accuracy, capacity, friction and so on.

Sliding contact bearing also called as sleeve bearing. In sliding contact bearing surface of shaft slides over surface of the bush results in friction and wear to reduce the friction and wear the surfaces are separated by lubricating oil. 

What are the Introductory Difference Between Sliding Contact and Rolling Contact Bearing 

sr. no	Rolling Contact Bearing	Sliding Contact Bearing
1	Size of Rolling contact bearing is smaller than sliding contact bearing.	Size of sliding contact bearing is is larger than rolling contact bearing.
2	Failure chance of Rolling contact bearing is higher.	Failure chance of Sliding contact bearing is lower.
3	Continuous lubrication supply needed.	Continuous lubrication supply not needed.
4	Rolling contact bearing is suitable for high speed application.	Sliding contact bearing is not suitable for high speed application.
5	Maintenance is less and long life.	Maintenance is more and life is short.
