Deep groove ball bearings creates a lot of noise.
Explanation: They create very less noise due to point contact.
There is problem of alignment in deep groove ball bearings.
Explanation: It is not self-aligning.
Deep groove ball bearing has immense rigidity.
Explanation: Due to point contact, rigidity is not so good.
Cylindrical load bearing has lower load capacity as compared to deep groove ball bearing.
Explanation: Cylindrical load bearing has a line contact and hence higher load capacity.
Angular contact bearing can take thrust as well as radial loads.
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.
In angular contact bearings, ____ bearings are required to take thrust load in both directions.
Explanation: Angular contact bearing has this disadvantage of needing two bearings.
The angular play bearing must be mounted without axial play.
Explanation: There is no tolerance of misalignment.
Taper rolling supports
Explanation: The line of reaction makes an angle with the axis of bearing and hence both type of loads can be carried.
Which of the following isn’t the property of taper roller?
Explanation: Due to line contact it can take high radial and thrust loads.
Which of the following cannot take radial load?
Explanation: There is no inclination in the line of reaction and hence only thrust loads can be carried.
