Lubricating Bearings

[spillage]

Hi All,

I have just purchased some new skf bearing to give my mount a bit of a service and was wondering if I should remove the rubber seals, clean  and re-lubricate with superlube or just leave as is? I was planning on re lubing the RA and DEC tapered bearing but not too sure about the others.

Cheers,

I'd be interested in people's opinions also, Ed from deep space products says not to..

If they are sealed bearings, then you don’t need to do anything.

open un-sealed bearings obviously need to be greased - less is more, don’t overfill them.

Less is more.... I thought you had to pack the grease in

Based on my 50 years experience as a professional mechanical engineer, you don’t need to “pack” bearings with grease. With astronomy gear we are talking about low speed, relatively low loads compared with critical heavy duty industrial applications.

No need to over grease.

Thank all for the info. I will leave the sealed bearing well alone and just lightly grease the tapered bearing and worm and crown. Just waiting for my spacer to come from the states.
