Question 1 of 27070

Q

An example of an antifriction bearing is a __________.

🔍 Key Concepts

• antifriction bearing definition and purpose • differences between rolling-element bearings and plain (sleeve) bearings • how thrust bearings and cutlass bearings are constructed and lubricated

💭 Think About

• Think about which option uses rolling elements (balls or rollers) to reduce friction between moving parts. • Ask yourself which bearings rely mainly on a film of oil or water between smooth surfaces rather than rolling elements. • Consider which type of bearing is typically used on propeller shafts outside the hull and what material it is made from.

✅ Before You Answer

• Identify which choice clearly contains rolling elements (balls or rollers). • Eliminate options that are primarily sleeve/plain bearings using a film of lubricant with no rolling parts. • Confirm in your notes how a Kingsbury thrust bearing and a rubber cutlass strut bearing are classified.
