So far it was a Chinese no-branded item, but I used it for about a year and tried to replace it. The movement became very smooth. I think that I also contribute to improvement in precision by reducing the play.

There was rattling in the retainer part, the built-in table breaks, so it did not become usable. Although it was possible to reduce blurring by shifting the center axis of the linear bush and the linear shaft, it is not satisfactory.

I bought it for the improvement of the Chinese made 3D printer. Accuracy has improved to not compare with the parts that were originally attached.

I bought it with the linear shaft at the same time. The creation of the working tool with goods as expected also was good and the accuracy was good. However, I would appreciate it if you can suppress initial grease application. Grease has spread to the surface of the product and it takes time and labor to clean.

It is exactly the same as the product so far, so it is the same. I am thankful that the price is cheap.
