💡 What is a pillow block bearing used for in CNC and 3D printer motion systems?

Pillow block bearings provide stable support for linear shafts, keeping motion aligned. - They help maintain shaft alignment and reduce wobble in guide rails. - They protect bearings from dust and debris for longer life. - Handy for DIY CNC and 3D printer builds where consistent performance matters.
