Between them I was able to make 2 sets with barely okay bearings and 1 set with awful bearings, the latter will go on the less used z-axis of what I'm building.The bad linear bearings are a range of jumpy and lumpy, to outright just skidding along without internal movement. I greased them up and hope for the best. 1 of the 500mm rails isn't as uniform as it should be, as the linears hit a point and require a bit more force to get past that bit, no doubt I'll have to locate and sand down that bit later.If I had the money to buy real parts, I would. Instead I've bought these 'cheap' parts (which the price dropped 23% immediately after buying - f-ers) which will just about do, but will not do for anything that will get a lot of use. I wouldn't use these on a 3d printer. I seriously considered sending them back, which is a rarity for me. the only thing that stopped me was that I was able to make the 2 okay slides and lets be honest, you get what you pay for. ### ⭐⭐⭐⭐⭐ Can't fault the parts much for the price *by P***M on Reviewed in the United Kingdom on 23 November 2020* I took what I thought was a bit of a risk given the poor reviews on this item, but can't fault the parts much now that they have arrived. All the shafts and leadscrew are straight. There is a little bit of play/backlash on the brass nut., which is normal. The slide carriages are also not super-tight and have a little play, but once mounted that goes away (note that there is no adjustment available on these). The only thing that does need some remedial attention are the bearing pillow blocks, as the bearings are not aligned straight and perpendicular; although, these can be tapped into place with a drift. I have had more expensive pillow blocks that have also needed attention so I guess it's common. ### ⭐⭐⭐ Problem with incorrect sized circlip on guide rail bearings *by M***H on Reviewed in the United Kingdom on 2 April 2020* I have a problem with the circlips that have been used to retain the bearing into the guide bearing. The circlip fasteners (2 holes where the clip pliers fit) are oversized and scratch the guide shafts meaning they won't slide freely. I'm going to have to remove and grind the clips so that they don't restrict movement. --- ## 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/125407592-glvanc-3d-printer-guide-rail-sets-t8-horizontal-8mm-lead](https://www.desertcart.pl/products/125407592-glvanc-3d-printer-guide-rail-sets-t8-horizontal-8mm-lead) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-04*
