Needle roller bearing packer
Needle roller bearing packer
(OP)
I have been Googling my butt off trying to find any information on this. We have several different types of bearings used in our landing gear area: tapered roller, sealed ball, thrust ect ect.
We have to pack our needle roller bearings with a popsicle stick, to push the grease into the rollers so the area between the roller and outer race is packed. I am trying to find a more efficent tool to do this...
This is a straight roller needle bearing, with rollers on the ID, and a lipped closed outer race on the OD. I don't think the cone shaped packers will work on this, due to the shape. Has anyone seen a tool which is made for this type of bearing? Or is a really fine needle the only way to inject grease into the rollers?

At least that's the way we did it back on the farm...
It is hard to get a sense of your actual bearing but this basic technique has to be better than trying to push grease in with a popsicle stick.

Packing these needle bearings is a process that takes place in a manufacturing environment. Thats why I would really like to a have a 'tool' to perform the job more efficently then by hand. I have an idea pictured, which would be a shaft with channels taking up the ID of the bearing, but not tall enough at the top, which would allow the grease to come out of the rollers at the top of the bearing.
The picture I attached to this post is very similar to the needle bearing we use, except ours has alot more rollers on it.

To use this with a needle bearing you need a dummy inner race that fits over the hexagonal shaft and fits up to the removable cone. The dummy race has to fit loosely inside the needle bearing. The dummy inner race also has to have a couple tabs on it to hold down the bearing.

Fill the middle with grease, then spin the whole thing really fast.

There are several MIL T.O.s on bearings that are truly outstanding. Everything You need to know about bearings... and a lot os extra info.
NOTE. I have-to have copies for the type work I do (I wish there were civilian equivalent manuals).
IF YOU CAN FIND THEM, these will be of extraordinary value, this/similar issues...
