Which of the following statements is correct concerning antifriction bearings installed on pumps?

🔍 Key Concepts

• Antifriction (rolling-element) bearings construction: inner race, outer race, rolling elements • How bearings are mounted on shafts vs. housings to prevent unwanted movement • Why alignment and interference fits are important for bearing life

💭 Think About

• Think about which bearing part actually needs to rotate with the shaft and which part should stay fixed with the housing. • Consider what would happen to the bearing surfaces and wear patterns if either race were free to spin loosely where it is mounted. • Ask yourself whether precision bearings are tolerant of misalignment, or whether misalignment tends to cause overheating and premature failure.

✅ Before You Answer

• Identify which race is normally mounted tightly on the shaft, and which race is normally mounted tightly in the housing. • Consider whether good bearing practice allows any race to be free to turn where it is seated, or whether a secure fit is preferred. • Confirm whether alignment is generally considered critical or not when installing high‑speed rotating machinery bearings.

Question 1 of 27070

Which of the following statements is correct concerning antifriction bearings installed on pumps?

Alignment is not a critical factor in their installation.

They are usually pressed onto their shafts.

The inner race should be free to turn on the shaft.

The outer race should be free to turn in its housing.
