my Amadeal tm25 was always a bit noisy from new but then started to sound like yours a few weeks ago so I changed out the 4 spindle bearings with good quality bearings and packed them with Klüber ISOFLEX NBU 15 grease and the differance is amazing it's probably only half as loud as it was when I bought it new I wish I'd changed them years ago
total cost for the bearings was £65 and luckily I have a friend who got me the grease because that's almost more expensive than the bearingsLast edited by Andybpowell; 02-12-2022 at 04:18 PM.

Hi Andy and thanks for the info.
I’ve been on to Amadeal who suggested I tighten up the retention nut, I have yet to do that but will take a look over the weekend. They also suggest it could be “incorrectly preloaded spindle bearing”.
Also if I run and put pressure on the spindle the noise stops and once I release it comes back, do you think this could be the bearings?
My issue is really with mine being brand new and unused I shouldn’t be really having to do all this. Amadeal have been ok about it but I’m yet to find a quick solution.
Can I ask you for a link to where you purchased the bearings, might be worthwhile.
Many thanks

It could be incorrect preload or just the poor quality bearings they use in the machines in the first place when I bought mine I spent a few days stripping it down cleaning it and reassembling with fresh grease from the factory they are not well adjusted it was time well spent and cut my backlash in half
the supplier I used were Simply Bearings Ltd
I'm not sure if your machine will use the same size bearings as mine I would assume so but you know what they say about assumptions
These are the bearings I used
1 x 6209LLBCM/5K NTN
1 x 6007VV NSK
1 x 32005X/Q SKF
1 x 32007X/Q SKF
You've got to partially dissasemble to check/adjust the preload so you could check the bearing sizes thenLast edited by Andybpowell; 04-12-2022 at 07:08 PM.
