🔍 Key Concepts

• Bearing races (inner vs outer) and which one should carry the press-on force • How side loads or hammering can damage balls, races, and motor windings • Why manufacturers specify using even, axial pressure when installing bearings

💭 Think About

• Think about which race is actually tight on the shaft and which one is usually a slip fit. • If you press or hammer on the wrong race, where does that force get transmitted through the bearing? • Which choice avoids pushing the rolling elements (balls) between the races during installation?

✅ Before You Answer

• Identify which race is being mounted onto the shaft (inner or outer). • Eliminate any option that involves striking the bearing directly with a hammer or mallet. • Choose the option that keeps force in line with the interference fit (the tight fit) rather than through the rolling elements.
