What is the primary use of pullers in millwright work?

Aligning shafts
Removing bearings, hubs, and sprockets
Measuring diameter
Cutting threads

The correct answer is: Removing bearings, hubs, and sprockets

The primary use of pullers in millwright work is for removing bearings, hubs, and sprockets. This tool is specifically designed to apply even force to the component being removed, allowing for efficient and safe extraction without damaging the surrounding equipment. Pullers enable millwrights to detach these components from shafts or other assemblies by gripping them and then pulling them off, which is essential in maintenance and repair operations in various mechanical systems. In contrast, aligning shafts involves different tools and techniques that focus on ensuring proper positioning and connection of rotating elements. Measuring diameter requires tools like calipers or micrometers rather than pullers, which are focused on removal rather than measurement. Cutting threads involves tap and die sets, which serve a different purpose in creating threaded holes or bolts, distinct from the pulling function of pullers. Thus, the correct usage and application of pullers make them indispensable for safely and effectively addressing maintenance tasks in millwright work.
