💡 What is a pillow block bearing used for in CNC equipment and automation?

They support rotating shafts in fixed housings to keep alignment and reduce wear.

• Shaft support in CNC mills and automation rigs for reliable alignment
• Reduces shaft play and improves repeatable motion in precise machining
• Chrome-plated steel variants resist corrosion in shop environments
