Question: 1 / 400

Which method of bearing installation is not recommended for slip-fit bearings?

By hand

Using a press

With a hammer

Using a hammer to install slip-fit bearings is not recommended because this method can cause damage to the bearing and the mating surfaces. When force is applied unevenly or excessively, it can lead to deformation of the bearing or the housing, resulting in misalignment, premature wear, or failure of the bearing. Slip-fit bearings are designed to fit into a housing with a close tolerance, and using a hammer can lead to an improper fit, where the bearing does not seat correctly or gets damaged during installation.

In contrast, methods such as using a press or appropriate installation tools apply force uniformly and allow for a controlled installation, ensuring a proper fit and reducing the risk of damage. This distinction is crucial in maintenance and reliability practices, where ensuring the longevity and performance of components like bearings is of utmost importance.
