Hi everyone! In this article, we’re going to explore an important concept in mechanical engineering What are the basic Difference Between Sliding Contact and Rolling Contact Bearing. This topic plays a key role in the Theory of Machines and helps in understanding how different bearing types affect performance and efficiency in machinery. So, without any delay, let’s dive right into the topic.

 

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.
