Igus Anet A8/A6 Upgrade Set Slide Bearings Instead of LM8UU for 3D Printers (12 x RJ4JP-01-08 Igus DryLin®)

Definitely better than ball bearing types in my case. But I also had to create and print my own mounting blocks as my printer didn't have the same dimensions.Using these and only 3 instead of 4 on the heatedbed made a huge difference reducing noise and smoother operation.Update: Many hours if printing shields for the NHS and the originals are still working awesome. My X axis ball bearings just started rattling so I've replaced those with these too. They are far smoother and quieter.The difference in print quality is day and night.Very happy

I recommend any one to upgrade to Igus bearings on their printer. My upgrade has resulted in much smoother movement over the cheaper bearings that it came with. At the price why even think about it, just do the upgrade, you won't regret it.

Purchased these to replace the original bearings on my Anet A8.I have had mixed success so far.. Since swapping i have had nothing but issues with my y axis which was working perfectly before..Not super impressed so far..

The product itself is great, but I bought them for a 3D printer, and it was not suitable at all. The bearings compress when held in place and bind on the bars. It is impossible to get them working reliably. Just something to note.

My A6 was very noisy before I put these bad boys on. Honestly I believe the best upgrade I've made to my printer. Would highly recommend.

Item as described, works well.
