Question
difference between antifriction bearing and journal bearing
 Question Submitted By :: Mechanical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Antifriction bearings have line or point contact whereas
journal bearings have surface contact.
Antifriction bearings are used for low load usage and
journal bearings are used for high load usage.

# 2
anti friction bearings are also called roller bearings
which is having a point contact hence it has less friction
as compared to journal bearing

Answer
# 4
dont get confused by term journal bearing. any bearing that
supports a shaft laterally is journal bearing.
anti friction bearings are of two major types:-
roller and ball bearing. the balls or cylinders contact area
bears the load. they are used up to DN number ( dia in mm
multiplied with rpm ) 5,00,000. above that hydrodynamic
bearings that use oil film to support load are used. Note
that journal bearing can be anti friction or hydrodynamic.
journal bearings support shaft laterally and take care of
lateral vibration. thrust bearings support shaft axially and
take care of axial displacement ( float).

# 5
whiel abv statement is true just one more thing to add
antifriction bearing r used for low speed upto 50m/s while
tht 4 journal bearing is 75 m/s
 
Is This Answer Correct ?    17 Yes 13 No

Answer
# 6
oh, i am sorry, antifriction bearings cant be journal bearing.
and the other two classifications are :- radial bearing and
thrust bearing.
up to DN number 500000, antifriction bearings are used,
after that hydrodynamic bearings are used.
