Question Voron 2.4 Fysetc bearing problem

Printer Model

Voron 2.4 R2 Fysetc

Extruder Type

Clockwork 2

Cooling Type

Stealthburner

Hi everyone, I'm a new and happy owner of a Voron 2.4 R2 fysetc kit. I finished assembling the printer, I configured some mods etc and so far no problems. After a few days and hours of printing, I noticed a noise from the bearings, to be precise (fortunately) I located them perfectly, and they are the 2 bearings with flange located in the front part. Basically, the two bearings in the front part of the belt tensioner a/b, if I use speeds like 300mm/s (only as travel, when printing I don't exceed 120mm/s), are noisy at times. The noise they make is that of spheres moving without any lubrication. I tried to see if I could do something to lubricate these bearings, but they are the closed type. What can I do??? if I loosen the belts the noise starts to decrease until it disappears, but the belt is too loose to be left like that. What can I do??? The whole kit is new and coming from fysetc. The printer has a few hours of life and printing time. After a while it presented this problem. I assembled the printer myself, following the manual.


PS: sorry for me bad english, i use Google Translate.

Hi, these bearings normally tend to have very little lubrication. You can re-lubricate them by removing top and bottom rings, and and re-pack them with lubricant.
There is this tool you can print and re-pack bearings. https://github.com/Annex-Engineering/Misc_Designs/tree/master/Bearing_Repacker

oh, thanks so much for the reply. So I can try to relubricate them without problems, right? Does the fact that if I loosen the straps the noise decreases have anything to do with my problem in your opinion?

Yes, repack them or buy new bearings. Bearings are machinial so if you change the tension in the belts you will get different results.

ok, thanks for the info. Today I prepared everything. As soon as I get home I try to lubricate them... at worst I'll buy them new... but if I had to buy them again, which brands are reliable?

Where are you located?

Find a reseller in your area and they often sell good bearings. https://docs.ldomotors.com/en/Oribter_Resellers

I am in Italy. Now I see the link you sent me. If I don't solve it, I already have spare parts. Thank

Update: I finally managed to lubricate the bearings... I had some difficulty opening them, but then everything went great. Thanks a lot to everyone

In a pinch, drop your bearings in some 20W50 motor oil and heat it up until it is hot to the touch. Then let it cool down and remove the bearings. The heat thins out the oil and lets it move past the seals. The cool down thickens it up so it stays in when you remove them from the oil bath.
