What kind of zerk is this?

[SIBUD]

Here is a pic of the grease zerk on my new CNC machine. It is straight shouldered, unlike the common ones found on farm machinery, cars etc. It also appears to be smaller in diameter.

Is there a name for it and where would I get a grease gun to fit it?

I don't recognize it, but my personal inclination would be to replace it with a US standard type of grease fitting.

The fitting should only take a minute or so to change, and having a standard fitting will make it easier (and more likely) to properly maintain the equipment.

Just my opinion..

It looks like it is on a hollow tube of some sort. What is on the other of the steel wall?

Those fitting are not unusual in the industrial manufacturing industry. I've never seen one quite like that but if you look directly into the end of it, does it have a spring loaded ball? If so you attach this to the end of your grease gun hose. When you press the pointed end of this into the fitting it unseats the spring loaded ball in the fitting.

Like was said earlier, you can replace it if it's threaded into the machine. If it's not threaded it's a press fit and can be pulled out and another regular type of zerk pressed in.

Yes, it does have a spring loaded ball at the end.

Thanks.

The bearings on which my Z axis mount rides.

I think it may be one of these pin type grease zerk found here:

Looks to me like a oiler port that you need a pump style oil can to inject oil into it. Just like a lot of mils and lathes. Norm

Thanks for the info!
