Lubricate Roller Bearings or not?
I have a new GSO 12" Dob which has an azimuth base needle roller bearing disk that sits between two aluminium disks. This setup seems to work just fine and there was no lubrication on it when I assembled it. So the question is: does a needle roller bearing like this need any sort of lubrication at all? I was thinking of maybe hitting it with some Dryglide spray is anything. I hate the thought of using grease on it because that's just going to act as glue for dirt in my opinion. What's the go?
BTW I did do a search here before I asked and there doesn't seem to be much on these types of bearings and lubrication.
