BEARING MCQ
1) The bearings in a car wheel are subjected to
Radial load only
Thrust load only
Both radial and thrust load
Neither radial nor thrust load
Correct Answer- (C)
2) The construction feature which makes tapered roller bearings unique is that races are
attachable
separable
self-aligning
none of the above
Correct Answer- (B)
3) The advantage of the tapered roller bearing is that

lubricates
turns
restraints
none of the above
Correct Answer- (C)
9) Which of the following bearing is used for high axial thrust load ?
