Good day
So I have 16 hiwin hg15 blocks in my setup and they all shipped with needle style zerks. I took the 4mm plug out of the front and installed them
I did notice when I go to lube with grease gun and needle that 90 percent of it wants to ooze out the needle instead of going inside the bearing. I'm using a lithium base nlgi 2 grease. It's like it's blocked inside the bearing and won't let grease in. I can't grease externally as the wipers won't let much pass through and into block.
Do I need to do anything special? Do I need to make a hole once I remove the screw and insert the fitting? The fitting is on the end caps (red) face just above the linear rail. There are side ports and a top port but those are not drilled or anything from the factory.
Any input would be much appreciated.
I also seem to see this with the ball screws as well. Lube using a standard zerk seems to want to just ooze out around the seal after maybe half a pump. But it only oozes out on one side seal and not the other. I want to make sure I'm getting grease throughout the bearing
