Greasing Hiwin HG15

[EddyCurrent]

First thing is, I would not recommend using the Hiwin size 15 linear bearing blocks because they are an abomination to grease. If though you do have them like I do, I found a good thread here about greasing them.

Ah I see it just pushes in at both ends. With it being captive in the aluminium plate it can't go anywhere so as long as there's a good seal at both ends it should be fine. thanks.

I spent an hour or two last week looking for some alternative fittings.
My Hiwin catalog lists a 90° oil fitting, but I have no idea where to get them from.

These might be able to be modified into something workable.

My machine has two Z axis, so I have 8 blocks to grease.

I also found these.
