🔍 Key Concepts

• Types of bearings and how they contact the shaft/raceway (point contact vs line contact vs area contact) • What diametrically opposite means in terms of geometry on a circle • How load is distributed in needle, roller, ball, and tapered roller bearings

💭 Think About

• Think about which bearing design normally supports load at only a few small contact points rather than along a full line or surface. • Visualize the cross-section of each bearing type: how many elements are actually touching the race at any instant, and what does their contact patch look like? • Consider which bearing type is known for very small point contacts that can concentrate load but allow low friction.

✅ Before You Answer

• Be clear on the meaning of "two small points diametrically opposite" – that implies only two load-carrying contacts, 180° apart. • Review which of the listed bearings have point contact versus line contact between rolling element and race. • Eliminate any bearing type where the rolling elements would create extended line contact or a broad area of contact, since that would not match "two small points."
