This type of bearing offers minimum friction then other. In case of high fluctuation speed & load.

Mallikarjun Sadlapur said: (Sep 8, 2013)  
The main reason behind using plain bearings is primarily for its high load bearing capacity since it offers maximum bearing contact surface. Secondly, the friction for this bearing will be a little higher compared to other types of bearings but it will be overcome with suitable lubrication arrangements. Third important point is that this is they only bearing type that can be split and assembled for easy installation as in case of crankshafts.

Instead of saying plane bearings we can call it as journal bearing.

Why we choose this type of bearing?

Suresh Kumar said: (Sep 10, 2016)  
It can take axial and thrust load during working condition.

Is it hydrodynamic bearing?

@Viralkumar.

No it is not a hydrodynamic bearing.

What is plain bearing? Describe in detail.

Naveen said: (Mar 31, 2017)  
Plain bearing is to reduce the friction in sudden fuctuation loads @nd more economy the ball bearing and roller baering.

Good and superb explanation.

Anuj said: (Jul 22, 2018)  
Thanks for explaining the answer.

K.Manoj said: (Sep 21, 2018)  
Thank you all for giving the correct explanations.

Praveen said: (Feb 6, 2020)  
This also called as cell bearing.

A thin oil film is formed between shell which is fitted into bigger size of connecting rod and pin of crank shaft so that there is not metal to metal contact. It is shell bearings or plain not hydrodynamic.
