🔧 Ideaker Industrial Combination: Horizontal Bearings, Power Transmission, and Linear Motion Products Review

Poor quality and stability. The bearings slide well on one shaft, but rub completely on the other. One of the bearings slides fairly well on the second bar, meaning there are tolerances everywhere on both the bars and the bearings. Expect quality to match the price of these items - more or less cheap junk, useful only for gaming and not for creating anything useful, even at an amateur level.

the price is hard to beat. I used them in a laser engraver and they worked fine. My only complaint was that some of the support bars I ordered had rough edges where the sliders needed a lot more force to move. After sanding them down with fine sandpaper, they were fine enough that it wasn't a big problem. Still not bad for the money.

The lead screw and nut I received are excellent with little noticeable play. However: The rod holders are not correct. The top of the socket protrudes about 1.5mm above the top of the assembled bearing block which means that anything attached to the bearings cannot protrude past the socket unless you add a shim. It took me a redesign and hours of work because I couldn't wait for a replacement. On all other linear bearings/rods/support systems I've bought, the top of the bearing block was flush…
