🔍 Key Concepts

• Load and alignment effects on ball bearings in electric motors • How excess or insufficient grease affects bearing temperature and internal pressure • Manufacturer’s recommended lubrication practices vs harmful practices

💭 Think About

• Which choice describes a condition that puts abnormal mechanical stress on the bearing races and balls during normal operation? • Which options actually match good maintenance practice that usually extends bearing life rather than shortens it? • Think about how filling the entire grease cavity vs only part of it changes heat buildup and churning inside the bearing.

✅ Before You Answer

• Eliminate any options that sound like standard, recommended maintenance steps from a manufacturer. • Consider which action would most likely cause overheating, misalignment, or uneven loading of the bearing. • Ask whether the bearing needs space for grease to move and expand, or if packing it full is always better.
