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

This handy component supports the rail and helps keep it aligned for precise motion along long travel.

- pillow block bearing supports the rail and carriage under load - maintains alignment on long travel and reduces play - compatible with sealed ball bearings and ceramic options for low friction - ideal for CNC routers, lathes, and mills requiring accurate motion
