Please offer these with plastic dryliner bearings ### ⭐⭐⭐ 3.0 out of 5 stars Something is just not right about these bearings and the quality is just hit or miss. *by A***I on Reviewed in the United States 🇺🇸 on November 27, 2019* The media could not be loaded.  As seen in the video the black plastic bearing is the way they should work. Not too tight, not too loose but just right. The first bearing I move after the plastic one is very loose and the second is very tight. In the images, you can see that one of the bearings was shipped with no black metal piece to hold the bearing in on one side. Each bearing should have two black little metal pieces to keep the bearing inside. Just so everyone knows, I ran the bearings up and down the metal rod about 30 times or more to wear them in and the video shows how they respond afterward.Update (went from 2 to 3 out of 5 stars on the review because I finally have a working set):I just some replacements... Those had issues as well. This time all of them seem to have good bearings and have all the clamps to hold them in the housing. However, some of the new ones were not even threaded all the way through so the screws I had would not work on some of the new ones. It seems getting a WORKING set of these is a big shot in the dark. It's unfortunate though, the ones that are made right work well from what I can tell. My advice, if you need 4 order two packs of four and send back the defective ones. That's what I had to do but it took me over a week to get everything straighten out. ### ⭐⭐⭐ 3.0 out of 5 stars Has a design flaw. *by J***N on Reviewed in the United States 🇺🇸 on May 21, 2019* I've used these sliding blocks on my 3D printer and after repeated use I've noticed some of the C rings or retaining rings, however you call them that hold in the bearing, protrude out enough that they scratch the rods they slide on. I can't say for sure that I have them properly aligned, but I would still think the designer should have considered the damage these could cause at slightly off angles. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/60970734-3d-printer-slider-sliding-block-linear-bearing-scs8uu-motion-ball](https://www.desertcart.pl/products/60970734-3d-printer-slider-sliding-block-linear-bearing-scs8uu-motion-ball) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-07*
