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

This handy answer explains how bearings support rotating shafts and keep misalignment from causing wear in CNC and automation setups.

- Keeps shafts aligned for repeatable positioning - Reduces friction and wear for smoother operation - Works with BK12/BF12 end supports and standard rails - Ideal for DIY routers, lathes, and milling upgrades
