• Center load

Technician A says that bearings are used so no wear takes place. Technician B says that bearings support loads, but do not not align components. Who is correct?

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither Technician A nor Technician B

The friction between different metals in sleeve bearings is reduced due to a property called __________.

• Feasibility

• Compatibility

• Reliability

• Maneuverability

Technician A says that friction would be less if the metals used in sleeve bearings are different. Technician B says that sleeve bearings cannot have direct surface contact. Who is correct?

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither Technician A nor Technician B

Technician A says that antifriction bearings do not use rolling contact to reduce friction. Technician B says that antifriction bearings use sliding contact to reduce friction between two metals. Who is correct?

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither Technician A nor Technician B

Which of these bearings is designed to support only radial loads?

• Ball bearing

• Tapered roller bearing

• Plain roller bearing

• Plain bushing

Technician A says that in an interference fit, friction holds the bearing race in place on a shaft or in a housing. Technician B says that interference fit means the bearing’s inner race is slightly smaller, by a few thousandths of an inch, than the shaft to which it locks. Who is correct?

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither Technician A nor Technician B

Which of the following statements is true of interference fit?

• Bearings with interference fit can be easily installed and disassembled.

• A small amount of force is sufficient to remove a bearing with interference fit.

• Special service tools are required.

• Presses, hammers, pullers, and separators are the only tools used.

Technician A says excess lubrication would result in corrosion of bearings. Technician B says that excess lubrication would increase the temperature of bearings. Who is correct?

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither Technician A nor Technician B

__________ is a condition where chunks from the surface of the bearing rollers or races break or flake away.

• Trailing

• Spalling

• Stalling

• Strolling
