💡 What is a pillow block bearing used for in CNC machines and 3D printers?

A handy explanation: it guides shafts for accurate, steady motion and reduces wear during repetitive cycles. - Handy for providing stable, straight-line motion in compact setups - Reduces friction and wear to extend service life under load - Works with standard rail systems like MGN7 for precise positioning✝️
