Naerok mill spindle runout

Good to see your report Kim,incidentally does the manual cover much in depth?,does it tell you the t nut size for the table slots?

I also have an RDM350. It's a nice compact machine. Interesting to see the spec sheet Kim. I'll use it to assess mine

The manual is not much use it very generic it has 8 pages and 2 of these pages has the parts diagram and parts list I did manage to download a copy of this manual off the web I think I got the link from this site. there are no table slot dimension in it see link below

Hello Kim and other RDM owners, I've had a look at that address and its almost the same as my so called manual. The machine is so basic that its pretty obvious which each part does. If any one has the bearing manufactures part numbers for the bearings I would like to know of them. John.

I have just recently replaced the bearings in my Naerok mill drill they were relatively inexpensive I think around £40 with postage for the pair I will have the part numbers at home(currently at work) will post here when I get home.

Here are the numbers of the bearings I removed from my spindle

lower bearing:Ntn 4T 32007x Japan Mm

Top bearing:Ntn 4T 30205 Japan Lm

I replaced these with like for like,Ntn is a premium Japan bearing manufacturer and thought these more than adequate for the mill,even though others else where talk of putting in higher spec.I removed the bearings at work on an arbor press,but reassembled the new ones at home in garage with a bit of forethought and the freezer and pinching a spot in the oven in between the mrs making her cakes!
