### ⭐⭐⭐⭐⭐ Great ball screw set
*by A***R on July 10, 2024*

Great ball screw set. It's not aerospace grade $500 set but it's fine for what it is. The screw rod is SUPER HARD and I would try to design my project around the available sizes and avoid cutting it. Well packaged and ball screw rod and ball screw is double packed within a cardboard tube inside a cardboard box. The bearing blocks, aluminum mount and screws are well packed too.
