Answer

d) Loose rolling elements Explanation 1. Identify common bearing defects Bearings typically show defects through physical damage or operational issues such as noise, vibration, or temperature changes. 2. Analyze given options a) Corrosion or temperature rise: Common indicators of bearing failure. b) Dry or empty lubrication hole: Indicates lack of lubrication, leading to potential failure. c) Cracked or frayed insulation: Not related to bearings; more relevant to electrical components. d) Loose rolling elements: Directly indicates mechanical failure in bearings.
