Question 1 of 27070

A ball or roller bearing has an interference fit with the shaft upon which it is being installed with a hydraulic or arbor press. Upon what surface should the sleeve of the press be applied?

🔍 Key Concepts

• Interference fit between a bearing and a shaft • How force is transmitted through a bearing’s inner and outer races • Preventing damage to bearing rolling elements (balls/rollers) during installation

💭 Think About

• When pressing a bearing onto a shaft with an interference fit, which part of the bearing is actually being mounted to the shaft? • If you apply force to the wrong race, where does that force travel through the bearing, and what components might it damage? • Think about the path of the press force: from the press sleeve, through the bearing, to the part that is being fitted. Which surface makes this path as direct as possible without going through the rolling elements?

✅ Before You Answer

• Identify whether the interference fit is between the shaft and the inner race or between the housing and the outer race • Ensure the press force does not have to pass through the balls/rollers from one race to the other • Confirm the sleeve is applied to the race that is in direct interference with the part being fitted (shaft or housing)
