📏 High-Precision 8mmX300mm Linear Motion Shaft Diameter for Smooth Movement Review

Very smooth linear rails along the rail length. I have high standards for accuracy and this is a quality product. They definitely deserve 5 stars.

I had an unusual use for one of these wands. I used washers and drilled holes for the "hairpins" in the end. I drilled our outdoor table frame, outdoor umbrella stand and back through the table frame in a straight line. This new pole goes through the hole I drilled to keep the umbrella from exploding and away just like umbrellas did in the past.

I am building a jet engine model and have ordered a stainless steel shaft from another customer. It didn't work because it wasn't very smooth or very straight. I then bought this product hoping it would match the bearings I have on the motor. And surprisingly, it worked perfectly. It came with two poles, which was cool (in case one of them melted). And they were perfectly smooth. In general, the product is of very good quality.
