Default Stinger III - Greasing Hiwin HG20 Bearings

Hello!

I just purchased a used Stinger III and have a question about lubricating the HG20.

The fella before me said he kept it well lubricated. He would basically just spray the rails with silicone spray... Now I know from my Stinger 1, that you shouldn't grease the bearings like that.

I have the silicone based grease and a gun, however when I uncap the bearings, it is sealed on the insides. Is this usual? I checked all the grease ports and they all seem to be sealed.

Any ideas? I even looked at Hiwin's website.

There should be a little hole underneath that button head screw that will allow grease to get into the bearing IF you can apply enough force. Good luck.

Just remove the hex nut in the middle on either end of the bearing and use a grease gun to squirt grease in to it.

Use a rubber tipped fitting on the end of your gun and just push it on and hold it tight while giving it a pump or two.

The type of grease has been highly debated with lots of opinions over time.

There are lots of threads on this forum with pictures and such.

If you check HIWINS website they are very specific about what to use for grease. A couple of years ago a CAMASTER had discussion with HWIN and fell in line with the HIWIN company about lubrication and shifted from using oil on the bearings to using grease.

You can use any grease or oil you choose but the bearing manufacturer only stands behind what they recommend. I assume that is the case with CAMASTER as well.

That's what I originally did. When I was getting a lot of resistance from the gun, I checked the port. They seemed to be sealed. I just saw green all the way through.

I'll check again. I may just be blind.
