Hi Clark, I am a little late responding to this message but better late than never. I like your extended spindles. I have also machined a new spindle to accept 8mm watchmaker collets and it worked out

Good news. The motor mill fan cover had been compressed (presumably during shipment) such that it was binding against the fan, thus keeping the motor shaft from turning. When I went to disassemble the

Small correction there - Normal clearance is not C2. C2 is quite a tight clearance for high precision fits, and I doubt you'd find it readily available. Normal or C3 will be fine for the job - after

I suggest 6003-2RS bearings (IE sealed), normal or C3 depending on what is readily available. Use SKF or another respectable bearing company, not cheapo ones from China (except that some SKF bearings

For me or anyone else wanting to get bearings, we are having a lot of fulfilling discussions on the subject. However, can we figure some consensus that will tell me exactly what bearing number to buy,

Hello Keith, I?m very grateful for your outstanding explanations. There, I could find everything I wanted to know on the subject. Best regards, Ricardo.

Hello: I see. Just quoting a source, have no idea.? 8^/ Thank you very much for the heads-up. So the SKF samples I installed, which I do not recall having any markings on the box, would be 'Normal'.

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

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?
