So, I realize this video is a year and a half old. A beginner in the 3D hobby may be a bit confused by some of the comments here. Chris' video is spot on. There are comments here about precision of balls, every other ball should be a slightly different size, etc. This kind of stuff for home 3d printers is nonsense. For consumer grade 3D printers, the duty of the linear rail is super super light. Clean the rail, lube it (superlube or really any NLGI 1 or 2 lube. PTFE is fine also, for this level of use) and you're good to go. You can even use a light machine oil, just will have to do it more often. Nero said on his video many many times, just lube it and you will be fine. Superlube, Mobilux EP1, white lithium grease (yes, even the spray stuff) will be fine. We're not on the International Space Station trying to make a part to get us home........you're good. Really.

A note on lube: Hiwin recommend lube with "no solid particles" in it - PTFE is solid particles. Graphite, copper, MOS2, and whiteners [Titanium Dioxide, Zinc Oxide] etc should all also be avoided. PTFE can also cause the balls to slide, rather than roll, which may actually increase wear. They also say that grease should be Lithium Soap-based and NLGI2 consistency. All of that said, the Hiwin specs are for much more heavy duty machines than printers, so the effect on wear will probably be less pronounced. It should also be noted that grease consistency also affects speed if you're doing speed benchies - thinner is faster. Grease manufacturers usually recommend NLGI 00 for 3D printer rails.

I bought THIRTEEN crappy linear rails and carriages to get SIX that I needed that were "good enough." I also didn't clean off the shipping oil, but instead just lathered on some Superlube grease. Next time I get up the courage, I should replace them all... **shudder**

I moded my Prusa Mk3 so many years ago to linear rails. I bought the cheap China ones and had to rebuild them to get them working smoothly. So, I did all things to you talk about but also took all the balls out and cleaned them. Those got things working quite smoothly. I have found over the years of using linear rails on my Prusa both my Delta printers that the light grade lube works best. You can buy online or in Craft stores needle tip applicator bottles cheap that you can then fill with your favorite light lube and put it right where you want it to go. Good job Chris on the video that should help many that want to use linear rails or maintain their rails.

The AISI designation of 52100 is the composition/treatment of the ball bearings. After the proper heat treatment and annealing process that particular stainless steel is very hard. Not surprised it dented your pliers. Definitely right about staying away from the chrome plated; they're like chicken eggs compared to the 52100.

Ball bearings for these rails are chosen per side by a technician at the factory. they actually have ball bearings of multiple sizes at the factory, all ever so slightly bigger/smaller than each other and they choose the best fit for each channel of the block based on the customers specifications. the balls on one side of a block actually may not be the same size as the balls on the other side. Replacing all of them with 3/32 balls will most likely either introduce slop or increase the preload of the block. This really isn't worth doing, and certainly won't make them better. just buy new ones, they are cheap anyways.

I'm going to make a wild stab in the dark here... but I reckon the cheap Chinese rails are made with no such care. But as it happens, I changed the bearings over on a linear slide just a few days ago. The slides had had been used, though not a huge amount. Here are 10 random measurements: 2.38 2.38 2.38 2.39 2.38 2.38 2.38 2.38 2.38 Reading 5 from the packet of chrome steel I am getting 2.39 from all of them All measured on a cheapo electronic digital caliper. The new slides are definitely are smoother, with the slide having less slop. But bear in mind I had lost some bearings on at least one of the slides

One tiny tip- any time the slider is off the rail always keep a paper towel or some kind of soft surface under it so that if the bearings pop out they can't bounce away or bounce at all- they'll settle where they first drop. Also, never try to save something you drop, watch it until it settles/stops moving- too easy to miss the save and lose it even worse by slapping it across the room ;)

I just now got to the point of wanting to install them, however, the rails now have rust on them - just sporadicly but rust nonetheless and it's just surface rust and the rails are still very solid.

If you have bought the cheap rails, instead of buying 100 ball bearings. Buy 1000 chrome steel ones. The way the pricing works it is usually a marginal price difference. The cheap ones I bought had crappy ball bearings, don't know what they were made of, but all of them, rather than just adding more changed the bearing's smoothness substantially.

@@ChrisRiley I bought a thousand from Amazon in the week before Christmas. I got sent two packets in error, so I will have enough to last me the rest of my life. I would try and send them back, but Amazon makes this just about impossible. The last time it happened, I sent the extra item back only to be refunded.

Have C carriages benefits compared to H carriages?

@ChrisRiley 8 ай бұрын

Basically, one cart is a little longer than the other. Gives you a little more area on the rail.

It depends how much, you might have some missing ball bearings.

Sounds like your linear bearings are missing some ball bearings. Or they are just really worn.

They are good enough for 3D printing. Just service them before you use them. If you really want to improve them, buy 1000 chrome steel bearings and replace the low quality ones in the linear slide.
