Question 1 of 27070

Ball or roller antifriction bearings are used to support GTE rotors for all EXCEPT which of the following?

🔍 Key Concepts

• Ball and roller antifriction bearings purpose in machinery • Difference between reducing friction vs increasing resistance • Types of loads bearings are designed to carry: radial, axial, and shock (overload) loads

💭 Think About

• For each option, ask yourself: does this describe something bearings are designed to DO, or something they are designed to AVOID? • Think about what "antifriction" means in terms of rotational motion and resistance. • Consider which functions are common, desirable characteristics in high‑speed gas turbine engine (GTE) rotors, and which would be harmful.

✅ Before You Answer

• Verify which choices describe benefits of antifriction bearings (what engineers want from them). • Identify if any option describes an effect that would worsen efficiency or increase wear on a high‑speed rotor. • Check which loads (axial, radial, momentary overloads) high‑quality bearings are specifically designed to handle in rotating machinery like a GTE.

Question 1 of 27070

Ball or roller antifriction bearings are used to support GTE rotors for all EXCEPT which of the following?

To accommodate both axial and radial loads

To offer maximum rotational resistance

To facilitate precision alignment

To withstand high momentary overloads
