Ball Bearings Quiz

What type of ball bearing uses axially asymmetric races and supports combined loads?

• Deep-groove ball bearing

• Axial ball bearing

• Angular contact ball bearing

• Preloaded pairs ball bearing

Which material is mentioned as being used in angular contact bearings to reduce centrifugal force and function well in high-temperature environments?

• Silicon carbide

• Silicon nitride

• Aluminum oxide

• Titanium nitride

What is the main advantage of using preloaded pairs of bearings?

• Reduces the total load capacity

• Increases the radial load capacity

• Improves the axial runout by taking up necessary clearance

• Allows for a choice of contact angle

In a deep-groove radial bearing, what is the main characteristic of the race dimensions?

• They are larger than the dimensions of the balls

• They are smaller than the dimensions of the balls

• They are close to the dimensions of the balls

• They are adjustable

What is the main function of an axial or thrust ball bearing?

• To support radial loads

• To support axial loads

• To support combined loads

• To support preloaded pairs

Who invented the Conrad-style ball bearing?

• Robert Conrad

• Thomas Edison

• Nikola Tesla

• Alexander Graham Bell

What is the main advantage of a slot-fill bearing?

• Higher radial load capacity

• Lower cost

• Easier assembly

• Longer lifespan

What is the primary disadvantage of Conrad bearings?

• Limited number of balls can be loaded

• High cost

• Difficult to assemble

• High maintenance

What is the main feature of relieved race ball bearings?

• Reduced outer diameter on one side

• Increased inner diameter on both sides

• Reduced inner diameter on one side

• Increased outer diameter on both sides

Which type of bearing design allows for more balls to be assembled into the bearing?

• Slot-fill

• Relieved race

• Fractured race

• Single-row
