Is this a bearing buddy?

Two years ago I blew out both bearings on the curb side of my 1997 Scamp 13. Flatbed towed to a trailer place, they fixed it and I went on my way.
Today I jacked up the trailer to inspect and, if necessary, repack the bearings and this is what I found where I expected a castle nut.
The wording says Dutton-Lainson. I found their web site, they are trailer parts suppliers, but I couldn't locate an image to match the one I attached to this posting. Wondering what I need to do to make sure the bearings are OK, and if I need to obtain a special applicator to squirt in some grease.

I plan on replacing the entire axle this year with something that has electric brakes. I don't need info on that aspect - there are hundreds of posts, I'm just mentioning it because the existing axle only has to last through the summer.
Thanks!

That looks like a dust cover of some sort. If so it just pops off revealing the spindle nut. just like an ordinary dust cover or a Bearing Buddy.
It appears to have a little bleeder button for use much like the pressure plate on a Bearing Buddy.
It clearly is not a Bearing Buddy.
That looks like an ordinary zerk, but go easy on the grease gun and probably press on that button ( maybe to release extra pressure.
I have never seen one like it so this response is largely speculation.

Dutton Lainson sells these as "Grease Keeper caps" in several sizes. The description for one says:
1 inch Grease Keeper dust caps with grease zirk and pressure relief valve. Protects wheel bearings from water and dirt with a positive hub seal. Supplies a reserve of lubrication and has built-in positive relief. Longer time between periodic repacking of bearings. Protects and extends bearing life. Zirk permits frequent greasing and relief valve eliminates excess pressure on grease seal. No complicated moving parts or gaskets that require costly maintenance and replacements. Easily installed in seconds, no need to remove hubs. A positive hub seal minimizes water entry when wheels are submerged. Zinc plated finish. Includes two protectors, each with a vinyl cover. Also fits 1-1/16 inch spindles.

Since it sounds as though you have no brakes at present, you won't run the potential risk of having excess grease contaminate your brake shoes.

I suggest you either repack the bearings or have them repacked. Part of the repacking process is bearing inspection. Just pumping grease into the bearings with inspection I believe is still looking for trouble. I have EZLub spindles and hubs but have never in almost 14 years have never put a grease gun to zirk fitting and probably never will. At 13 years the bearings needed replacing, the cost was pretty low and done by a Dexter axle shop. Actually a utility trailer shop that specialized in Dexter axles.
