Industrial Combination,Ideaker 500mm Horizontal Optical Axis & 2mm Lead Screw Dual Rail Shaft Support Pillow Block Bearings & Flexible Shaft Coupling Set of 15

As far as I can tell, the lead screw and nut I received are excellent, with very little However, as follows I think the rod supports are incorrect. The top of the support extends about a full inch above the top of the rod. When assembled, the bearing block is positioned around 5mm above the top of the bearing block. If you do not add a spacer, anything attached to the bearings will not extend beyond the support. Because I couldn't wait for a replacement, I had to design a new layout and put in a few hours of work. Previously, every linear bearing / rod / support system that I purchased had the bearing block flush with or slightly higher than the support, so anything bolted to the bearing block would slide over the support. (Yeah, I know that the technical names for these parts are incorrect). One of the pillow block bearings got a lost ball bearing before it even made it into the pillow block. I would return it if I had the time, and ask for an exchange if I had the time. The distributors are probably counting on the fact that I don't know, which is what concerns them.

With the other bar, bearings grind completely. It remains to be seen whether the bearing on the second bar can slide reasonably well on the first bar, indicating that the bearings as well as the bars are all over the place. These items should be of a quality commensurate with their price In both hobbies and more or less professional contexts, it is more or less junk that can only be used for playing around, not building anything useful.

My mistake cost me a lot of time. Neither of the smooth rods was straight on the threaded rod, but the threaded rod was very straight. A return has been made.

There are few better deals out there for the price. This is how I used them in a laser engraver. There was only one negative thing in my opinion some of the support rods had rough spots on them where the sliders took a lot more effort to move Using fine grit sand paper, I sanded down the patches until their condition was good enough not to be an issue. This is still a good deal for the price.

Since I got the kit more than a month ago, it has been working perfectly for me.
