Linear Motion Ball Bearing
LM8UU For 3D Printer Pack of 4PC
- Linear bearing is a linear motion system
- Used for linear stroke and cylindrical shaft with the use of the bearing ball and bearing coat point contact, the steel ball rolling with the minimum friction resistance
- So linear bearing has little friction, and relatively stable, does not change with the bearing speed, can obtain high sensitivity and precision of smooth linear motion
- Model: LM8UU Bore Diamter (dr): 8mm, Outer Diameter (D): 15mm, Total Length (L): 24mm
- Smooth moving, low friction, high rigidity and long life.
- These bearings have proven to be long lasting and provide precise low friction linear movement.
- These ball bearing are fitted with two rubber dust sealed to prevent ingress of dirt, water and foreign matter.
- Great for Automation equipment / Electronics / Instrument / Robot / Food machinery / Packaging machinery / CNC machinery.

So. Much. Better.Should have bought these to start with.Worth the extra $.Haven't measured play yet, but by feel they are at least 3x better fit.

I didn’t have high hopes for cheap bearings but these are only cheap in price. I cleaned them like I do all bearings but they were not full of junk oil. Very minimal color change of my cleaning agent, if any. I lubricated they and proceeded to break them in. To my surprise, almost no side play. They operate smooth with no binding, a little noisy but all rod bearings are noisy. Overall VERY satisfied. If only I could find them in 12mm on Prime.

I bought two sets of four bearings for a pen plotter project. None of them would run smoothly. I tried oiling one, and greasing another one, and neither type of lubrication helped. I ended up just buying some expensive Misumi bearings which do run perfectly smoothly, will slide down the rail just by tilting it, and also have no play. There was a point in time where even chinesium bearings were sometimes okay, but this was extremely disappointing.

Not the best bearings in the world but what would you expect. They work fine for low load applications like 3D printers.

These are an amazing value for the money. I recently changed my Y-axis bearings with one of the pricey top tier manufacturer's options. After installing them, the rattling noise became unbearable. The bearings had almost 0.02mm of slack in them.I purchased these off Amazon for 1/4th of the price of the top tier ones. After installing I can say that these put the other ones to shame. The tolerances are spot on perfect. No rattling at all. And no binding at all. They are very very smooth. They are not whisper quiet, but they are less noisy than the stock Wanhao set.For the money, you literally cannot beat these linear bearings.I'm going to buy a few more sets to have handy for my other printers.Will certainly buy more of this brand.Well done!!!

I bought lm8uu bearings from 3 different brands. And this is the winner! Slides well on liniar rods. Works great woth my prusa mk3 printer. I wanted to note that each bearing comes in a single oiled pack. Other brands keep these in dry packs.

I am working on a Rook build (3D printer) and needed some of these bearing for the Z axis. I first order a set from AliExpress and they were awful! So I decided to buy these instead, and they are great! The four I got are all extremely consistent and smooth running. I did have some binding when I put them into the plate, but I figured out it was because the seams inside the holes were causing misalignment. Once I fixed that they have worked great! I don't think I'll ever buy any other linear bearings!

Presi per sostituire i cuscinetti dell'asse X della mia Anet A8,volevo qualcosa di devente senza dovermi svenare e senza prendere qualcosa di molto scarso, scorrono molto bene senza scatti rispetto a quelli originali. Ne avrei comprati altri 4 per il bed ma purtroppo sono attualmente non disponibili.

These are a massive upgrade on the cheap bearings that had previously plagued my printer, I had really bad z banding and this sorted the problem right out. I shall likely have some more od these as funds allow.

Pour le moment rien à dire je les ai acheté pour remplacer un roulement HS sur mon imprimante Prusa mini, à voir leur durée de vie dans le temps.
