MCQs on Types of Bearings
1 - Question
Deep groove ball bearings creates a lot of noise.
a) Yes
b) They create very less noise
c) Depends on the application
d) No reference frame for comparison is mentioned
View Answer
Answer: b
Explanation: They create very less noise due to point contact.
2 - Question
There is problem of alignment in deep groove ball bearings.
a) Yes
b) No, it is self-aligning
c) It aligns itself only in some particular cases
d) Can’t be determined
View Answer
Answer: a
Explanation: It is not self-aligning.
3 - Question
Deep groove ball bearing has immense rigidity.
a) True
b) No it has point contact and hence low rigidity
c) It has surface contact
d) It has line contact
View Answer
Answer: b
Explanation: Due to point contact, rigidity is not so good.
4 - Question
Cylindrical load bearing has lower load capacity as compared to deep groove ball bearing.
a) True
b) False
View Answer
View Answer
Answer: b
Explanation: Cylindrical load bearing has a line contact and hence higher load capacity.
5 - Question
Angular contact bearing can take thrust as well as radial loads.
a) True
b) False
View Answer
Answer: a
Explanation: The line of reaction at the contact surfaces makes an angle with axis of bearing and thus has two components, hence allowing it to take both type of loads.
6 - Question
In angular contact bearings, ____ bearings are required to take thrust load in both directions.
a) 1
b) 4
c) 2
d) 3
View Answer
Answer: c
Explanation: Angular contact bearing has this disadvantage of needing two bearings.
7 - Question
The angular play bearing must be mounted without axial play.
a) Yes
b) Little tolerance is adjusted
c) Little tolerance is necessary
d) Can’t be stated
View Answer
Answer: a
Explanation: There is no tolerance of misalignment.
8 - Question
Taper rolling supports
a) Axial loads
b) Thrust loads
c) Both axial and thrust loads
d) None of the mentioned
View Answer
Answer: c
Explanation: The line of reaction makes an angle with the axis of bearing and hence both type of loads can be carried.
9 - Question
Which of the following isn’t the property of taper roller?
a) High rigidity
b) Easy dismantling
c) Take low radial and heavy loads
d) All are the properties of tapper roller
View Answer
Answer: c
Explanation: Due to line contact it can take high radial and thrust loads.
10 - Question
Which of the following cannot take radial load?
a) Cylindrical Roller bearing
b) Taper roller bearing
c) Thrust ball bearing
d) None of the listed
View Answer
Answer: c
Explanation: There is no inclination in the line of reaction and hence only thrust loads can be carried
11 - Question
Which of the following cannot tolerate misalignment?
a) Angular contact bearing
b) Cylinder roller bearing
c) Thrust ball bearings
d) All of the listed
View Answer
Answer: d
Explanation: All of these require précised alignment.
12 - Question
Cylinder roller creates lesser noise than deep groove ball bearing.
a) True
b) False
View Answer
Answer: b
Explanation: Due to line contact, cylinder roller creates far more noise.
