According to the SKF handbook, and my experience, C3 is not the usual bearing everyone uses, although it is being widely offered on Ebay and similar places. Clearance are described as C2, Normal, C3,

Hi, I have got to know at least three motor manufacturers for the Emco Compact 5, so it?s not clear to me if there are significant differences among them, regardless if they are 110-120 / 220-240VAC,

Hello: You're welcome. Yes, maybe just good enough. The more I got to know my newly acquired U3, the more cost cutting design decisions made by Emco came to light and with it a certain sense of

Julius, I thank you for your comments, they have brought some valued information for my better understanding. I assume most unwanted radial play is eliminated by the usage of Belleville or

I have an Emco Compact 5 mill motor that doesn’t want to spin. It seems that the bearings inside the motor are seized as I can’t even turn the motor shaft by hand. Does anyone know the bearings

Hello: Yes I do.? 8^D Sorry, I referred to 'E''instead of 'C' and on top of that, did not post the link ( https://shop.eriks.nl/en/bearing-clearance ) properly. --- *A dmin :* we need to be able to

Hello: The OEM specification (page 3 - Emco Unimat Service Parts) says that part #5 - ZLG 60 0302 is a 60032Z (ie 6003ZZ). No mention of any 'E3' there. The original (ca. 1980) bearings in my U3 were

Hi, speaking about ball bearings for the U3, I do not have the need to carry on any replacement of the original ones. Having not long ago checked axial play and running smotheness, they seem to be OK.

Hello: If you have a car or a motorcycle, chances are you also have a mechanic you can trust. If not, maybe you know someone who does. A local mechanic can probably direct you to whoever sells them

Just look for authorised distributors. There's probably a list of such on the SKF website. There's lots of other high end brands out there too that do equivalent products. Timken, Koyo and FAG to name

How can anyone do that I would think that is very hard to do in today's times of "snatch it and run" Phill

Thank you all who responded! Much appreciated. Now I do see a lot of places online that sell these SKF 6003 SS / 2RS bearings. Anybody can recommend an online reseller that can guarantee from fake?

I've got one similar to that in ER32 for my tool post grinder project. 19mm shaft, IIRC. Got the last dribble of parts for that and the Unimat 24vdc motor conversions the past couple of days. A chunk

Hello: Quite so. Inexpensive and easy to find, with all quality* brands having them in their catalogues. * SKF, NSK, Timken, FAG, NTN and a few others. I use the 6003ZZ single row (non-contact) double

The spindle bearings on my U3 are both 6003 size (17x35x10mm).?? That is a very common size and should be readily available from most bearing suppliers. ? I use the 6003 2RS variant.?? 6003 ZZ

Lots of fake SKF bearings around! Buy with caution. The U3 bearings will likely be a standard size, take one out and see if it has a code number printed on the side. Measure the dimensions and search

One of the ER16 collet variants I bought has a parallel shaft out the back about 150mm (IIRC) but crucially has the same diameter as the tailstock "shaft" - I got this with the idea of making a

Had a chance to talk to Guhring today, to a man with the relevant experience. He reckoned HSS would do the job but recommended HSCo (HSS with cobalt) as they can get a much sharper edge on it. That is

Hi, I bought a couple of different variants on these but haven't got round to doing anything with them yet...... Cheers Richard
