Default the Greaser for bearing maintaince

Hey guys and gals

Is anyone using Precision RC Products the Greaser? I saw one a while back in a video or somewhere else but can't find much talk of it on H.F. , If nothing else I figured it would be great for my 1/8 cars.
When I purchased it I also picked up some of Pete's Hobbies Recommended grease, Multipex Red NLGI #2.

If you are using this on your heli which bearings are you greasing, are you spinning the bearings up after repacking to loosen them up, and what is the smallest bearing and heli you have used this on?

I've never used it but the people that have swear by it. If you go to the Main Forum and search for "greaser" you'll probably find some threads about it. I think there was a new thread about it started not long ago.

Thanks Larry
I did a quick search but only in this section. Next time I'll remember to search the main forum.

I use mine all the time. I've used it for more for non-RC bearings than anything else. The smallest bearings I've done were on my Warp main shaft

I will continue to use my Greaser no matter what.

Wasn't this product discontinued? I ask this because I was interested in this as well a few months back but could never find one.

Pete's Hobbies (online) is where I got mine. I've also read the debates about it packing the bearings with to much grease and not allowing the balls to freely roll. I know its recommended to use a drill or such to spin it up and work some grease out of the bearing before reinstall. I ended up purchasing a tube of Pete's recommended grease, Multiplex Red. I also had read that Lubriplate Electirc motor bearing grease is good also. You can get the Lubriplate grease thru Ron Lund. Maybe I'll maiden the greaser on a few bearings on my 450.

Default Miniature Bearing Packer

Hi everyone,

I recently made a CAD drawing of a 2-piece miniature bearing packer which uses a standard insulin syringe to inject the grease. It's sized to fit tiny bearings found in the tail grip of a 450 all the way up to bearings nearly 1" in OD. I had a friend machine up a prototype out of aluminum for me and it works fantastic!

What do you think the interest would be in a tool like this if I were to have a batch manufactured and sell it as a kit (the bearing packer with a syringe) for under $30.00?

I ask because I know there are fans of greasing RC bearings out there (like me), but are there many of us? I just can't believe someone else isn't making a simple, inexpensive, miniature bearing packer already... or have they and I've missed it?

Note that I'm aware of the Precision RC Bearing Greaser (I have one), but it's big, a tad on the expensive side, and overkill for smaller bearings.

Best regards,

John

No... I decided not to pursue it after all.

Gyro,

Would you be interested in posting your drawing for the bearing greaser?

Hi Guys,
Anyone smart enough to come up with a design for a substitute for the Precision RC Greaser, particularly for bearings as small as 5mm outside diameter? No suggestion here that this should involve infringing the intellectual property rights of Precision RC or of Gyropilot.

Can it be done?

Any information gratefully received.
Thanks for taking the time to read this post,
Tony

Hi Tony,

I have a miniature bearing packer prototype made up by a machinist-friend and it works great!

I'm so thrilled with the concept, that at one time I looked into having it manufactured. But between the initial upfront cash investment needed to start production, the hassle of selling, taking orders, collecting money, packing, and finally shipping, I decided it just wasn't something I wanted to take on. I've got WAY too many "hobbies" already and so many other things on my plate that adding "tool merchant" to the list isn't going to happen.

BTW, I once tried to convince Lynx Heli they should make and sell something like this. I think they (or a similar RC heli company) would be well suited with their existing manufacturing connections and retail infrastructure. But I guess they figured it wouldn't be a good seller as nothing ever materialized... as far as I can tell anyway.

Later today I'll try to post the sketch used to make my prototype and some photos of it. You're more than welcome to take it from there. I'd love to see someone make these.

Best regards,

John

Default Mini Bearing Packer Photos

Attached are photos of my prototype miniature bearing packer. The bearing used for the photos is 10mm OD x 5mm ID so you can get an idea of the size. The smallest ID bearing this packer can accommodate is limited by the OD of the 4-40 machine screw in the center (approx. 1/8"). The largest bearing the packer can accommodate is limited to the OD of the packer itself, which is just under 1".

The packer uses a common insulin syringe (available from most drugstores) to inject grease under pressure. I fill the syringe directly from a tube of Tri-Flow TF23004 Clear Synthetic Grease.

A sketch of the packer and some 3D renderings will be attached to another post (running out of room on this one).

Regards,

John
