Bearings, especially lower ball bearings, guide the round over router bit along the edge of the workpiece, ensuring consistent and smooth results. The presence of a bearing allows for template or pattern routing and helps prevent over-cutting. Some bits offer miniature bearings for tight spaces, while others have standard bearings for general use. For example, the Amana Tool MRR108 features a 3/16" ball bearing for precise work, while the Amana Tool 49504 includes a standard lower ball bearing for versatile routing. A wide variety of bearing types and sizes are available to suit specific routing needs.
