💡 What is a pillow block bearing used for in CNC and DIY linear motion systems?

Handy explanation of how these bearings support shafts and keep motion smooth:

- Keeps shafts aligned and reduces wobble in moving assemblies
- Enables long, steady travel with minimal friction for precise cuts and engravings
- Suits CNC setups, engraving rigs, and automation fixtures where rigid support matters
- Works with sealed ball bearings and various sizes for different layouts
