Question 126Motor Plants - QMED

The correct answer is A) precision bearings. Babbitt is a soft, low-melting point metal alloy that is commonly used as a lining material for precision bearings. This is because the Babbitt alloy has excellent anti-friction properties and can withstand high loads and wear. The Babbitt lining helps reduce friction and wear on the bearing surfaces. The other answer choices are incorrect because shim stock is typically made of thin metal sheets, valve seats are often made of harder materials like steel or bronze, and salt water piping is usually made of corrosion-resistant materials like stainless steel or non-metallic composites, rather than Babbitt alloy.
