Here is the deal. There are two types of bearings used in timmy triggers. One is the super high quality bearings that are used in the critical trigger, the Assassins trigger, and the techna trigger. The bearings are SUPER smooth, but most importantly the inner sleeve is slightly wider than the outer sleeve, this way the trigger never rubs the body.

Obviously if you put RC Car bearings in the trigger, yes the trigger pivots slightly better, but you still encounter frame rub which slows the trigger down.

Does anyone know where you can buy those 3/16 inner, 5/16 outer (Thanks Dan911) precision flanged bearings that Techna/Assassins/Critical uses in their trigger? I want to mod my stock species claw trigger with these bearings and I dont know where to look.

Thanks guys

http://www.bocabearings.com/default.aspx might find some there

good find, I'll see what I can find

obviously Jason @ Techna and Jared @ Assassins order those bearings from somewhere, we gotta figure out where

[Rendition Tech (Banned)]

you see these bearings here-







it's the same bearings in all three triggers

[fiero32v]

heres another http://www.dynaroll.com/catalog/pag048.htm
i know you can get them with open sides , metal shields , rubber seals and teflon seals. ive had all types in my r/c cars

[invader zim]

VXB used to have the right bearing, but they aren't listed anymore. They were $5 a pop.

EDIT: I don't think Critical uses a flanged bearing. I don't have one to look at, but from the picture, it doesn't look flanged.

The Assassin trigger and the Techna have a bit of a recess where the the bearing goes.

[Rendition Tech (Banned)]

actually its the inner sleeve that sticks out slightly

this way the sleeve acts as a spacer, and spaces the trigger slightly away from the frame so it doesnt rub

zim!!! the one man who can help me here

any idea who else might sell it? Do you remember what it was called?

[Rendition Tech (Banned)]

.375

.625

0.1562 5/32

[raymius (Banned)]

I don't think VBX had the correct ones. They were flanged for the trigger, but the inner race was not flanged. The bearing run $10.80 each at Boca, abd they are the ones with the flange on both the outside and the inside.

3/8x5/8 is the wrong size. The size you need for the trigger screw to fit through is 3/16, and the size of the bearing inside the trigger is 5/16 od. You can find 3/16 id x 5/16 od flanged or none flanged from the link below. You can also find the size 3/8 by 5/8 there also.

whoops I knew it was 3 and 5 something, thanks for the heads up.

There problem is that when I type in "flanged" it gives me these-

http://www2.gpmd.com/image/a/ascc4602.jpg

which is the wrong type of flange. I need the inside to be flanged out, not the outside.

Flanged is probably the wrong term. Its more like I need it to be "Spaced". I wish I knew that the term was for a slightly wider inner sleeve than the outer sleeve

i think that why cp triggers have a spacer . with mine if i tighten it to much it still binds .i think it need one on the screw head side as well

[Rendition Tech (Banned)]

thats exactly right. CP uses a spacer instead of the bearings Assassins/Critical/Techna uses. It's CP's way of getting the trigger away from the body.

I think the width of the bearing is a standard 0.1562 (5/32) wide. We need a bearing with the inner sleeve being slightly wider, maybe .18th of an inch wide

If we could figure out what bearing they use, we can buy it, drill out the stock/OEM triggers and have a super fast trigger for dirt cheap

[fiero32v]

if you can find some small washers the fit the triger screw that dont rub on the outer race, you could use them as shims . that's how the differential bearing are shimmed in my nitro r/c truck

[Rendition Tech (Banned)]

possibly a disk harrow bearing? is that it?

maybe a 3/16 x 1/8 shim? Not a bad idea, but if you have noticed the difference in quality between RC Car store bearings, and those techna/assassins/critical bearings, it's night and day.

We got to find a way to figure out what bearings they are using

[fiero32v]

those might work if you can find in the right size

if you get the ones that the sell individual they're junk metal shield bearings . they dont carry high quality . one of the 2 link i posted earlier ask for tolerances when ordering . both are better than what you would get from a hobby store

Mcmaster 3759T33 ABEC-7 flanged double shielded. The sweetest trigger bearing money can buy, sir. I recommend using a light adhesive CAREFULLY everywhere so that the ONLY rubbing is from the ball bearing. A correct setup will swing freely on a pencil, when flicked, for well over a minute.

Sometimes you have to ask...Why does lurker have this bookmarked

Lurker is all that is man

I bow to my sensei (bows)




Lurker are those what Techna/Assassins/Critical use? With the slightly wider inner sleeve?
