The plastic rails that came with my 3018 were warped and never tracked smooth. I replaced with this product and now a very smooth operation

Unfortunately I received unthreaded slide blocks screws hole, which was very disappointing, the bearing quality to be honest was great, and very smooth.

These bearings have the normal dimensions for SCS bearings and are bolt-in replacements for my 3D printer.The 8mm ones I got have four rows of balls, which is typical.Smooth operation.The seals are tight enough to scrape dust and detritus off the rails and keep the bearing clean inside.They came individually sealed in plastic bags to keep them clean and dry.They were not covered in oil like some other brands I've bought before. Makes installing them much faster as I don't have to clean that all off. Just add a little grease inside, and bolt in place.

The HiPicco Linear Slide Blocks arrived in a plain box with each block individually wrapped. Each one had a thin layer of lubricant on and in them.Upon inspection, this set is not machined to super tight tolerances. Each exhibited a few rough edges, burs or scuffs. I tested a few shafts with the blocks and the linear movement was good enough for my prototyping needs. I didn't notice any huge wobbling, jamming or grinding while testing.These would be perfect for tinkerers or DIYers.

I used this product in my custom designed router lift for my old router and router table. This is a perfect fit for my purpose. I now have a smooth accurate way to adjust my router bit height thanks to this product. I used 4 bearing, as shown in the picture.

What is there to say?These are very good quality linear bearings. They feel very sturdy and well made.

I got these to use on a project running on 15mm copper pipe so my needs were never going to be precise, these are perfectly fine for that kind of job but the aluminium body immediately limits how heavy duty a task they can handle, they are deceptively light.I have no complaints so far so as long as you spec your job accordingly you won't be disappointed, the pricing isn't stellar for the quality but it could be worse.
