Custom Monster Truck Chassis.. Mike Please Build.. :)

[aqwut]

Yeah, I guess that makes a lot of sense.... Having bigger balls is better.. :)

[Serum]

It could be a matter of a thicker wall around the balls.

Procharged; the 15x8x5 bearings are impossible.. Very true.. the only option i could think of was to either make the holes bigger or get 15X10 bearings and make inserts for them.. (which is a relative weak bearing)

[aqwut]

what size are the rollerblade bearings?... the ABEC1, 3, 5, 7

No, they do not support 16mm bearings, only 15mm.

T/E-Maxx 1.5 & 2.5 Axle Carriers
T-Maxx 2.5R & 3.3 Owners - Click Here for the proper Axle Carriers for your truck.

Stock bearings and axle carriers aren’t quite strong enough to handle the punishment T/E-Maxx owners dish out. In addition, more strength is needed at the axle carrier when offset wheels are used or when aluminum accessories and oversized wheels & tires add more weight and stress to the driveline. Once again, RPM steps in where no one else has! We have completely redesigned the axle carriers for the maximum amount of strength and durability and included some seriously beefy 15mm. bearings to top it all off! Check out this incredible list of features:

RPM Axle Carriers
Stock replacement – no modifications necessary for RPM carriers to fit.

Larger bearing bores that accept RPM Oversized 15mm. bearings.

Includes four RPM 15mm. bearings in the kit – nothing more to buy.

Beefier, thicker walls and ribs for the ultimate in crash protection.

Double-ribbed steering arm / toe link arm for undeniably stronger and more rigid steering control and toe angle stability.

Stepped front surface to prevent plastic wheels from hitting the axle carrier under high cornering & jumping loads.

Molded from our bulletproof and lifetime guaranteed blend of nylons for unsurpassed breakage protection.

Molded in black, blue, & purple, as well as a dyeable white, that will allow anyone the most versatility with respect to color choices.


Stock 12mm. vs. RPM 15mm.


RPM Oversized 15mm. Bearings
A full 15mm. in diameter – that’s 3mm. larger than stock!

1mm. wider than stock bearings, with 2 bearings per axle, that’s an extra 2mm. per axle of contact with the axle shaft for smoother, longer-running performance.

100% Stainless steel construction for rust free dependability and its longer-wearing characteristics versus chrome steel bearings.

RPM Bearings have friction-free blue nylon seals for the ultimate in dirt protection and can easily be cleaned using our RPM Bearing Blaster (#81170).

Actual bearing ball diameters are a full 33% larger than stock.

RPM oversized bearings have more than twice the load rating of stock chrome steel bearings and have over three times the fatigue life of stock as well!

Prelubed with lightweight oil for efficient & minimal rolling resistance.

RPM axle carriers are sold in pairs. One truck will need two pairs to cover all four corners of a T/E-Maxx truck for complete, RPM bulletproof protection. RPM replacement oversized bearings are sold in sets of four bearings per package.

Tech Notes: Associated MGT owners can benefit from using RPM Steering Knuckles / Axle Carriers by combining these axle carriers with our #80010 Pillow Ball Setscrews & Bushing Caps. This package comes with spacers that prevent the bearings from binding on the MGT. Read more here.

Almost all buggies and truggies uses the 8x16x5mm bearings. I did not go for it, simply because I thought that the 6x16x5 incorporates larger balls and thus, they are more corrosion resistant.
I think the 8x16x5 ones has smaller balls.

Actually Captain, there are (3) types used in Supermaxx Racer-X and EXT steering knuckles. You neglected to mention the 6mm x 15mm x 5mm bearings. Robin later upgraded the knuckles by enlarging the bearing bore to 16mm thus allowing greater strength (although minimal) and the option to go 8mm x 16mm x 5 mm for the 8mm Supermaxx cvd's. The more significant value of the 6x16x5 bearing is availability and selection in the bearing marketplace.

I thought about upgrading the rpm knuckles to 16.. I think a lathe and a holder would serve a good purpose here.. Or perhaps a simple reamer does the job allready.

Yeah, I neglected it on purpose, since I thought there were no UE knuckles that would accept the the 6x15x5mm bearings. I bought these bearings from Acer Racing in ceramic form. I had to make some 1mm sleeves for them inorder to fit them in the RacerX knuckles.:p

[Serum]

yeah, you posted a pic of those sleeves. No issues with them? they don't pop out?

[Procharged5.0]

For better or worse my generation version of Racer-X has 15mm but the rest is equal to the current model. I even have the "High Impact" lower front arms.

[captain harlock]

They dont pop out at all. Like they were created exclusively for the racer x knuckles.

[Serum]

if they don't use a flanged side, they will go out, unless they are pressed/loctide in place... no way around it.

@procharged. they can be made 16mm. it is doable.

[captain harlock]

Yeah, they snug in the holes very tight.

[Serum]

did you need a press to put them in place then?

[captain harlock]

There is some resistance when you put them inside the knuckles.
Its extremely difficult to take them out once they're in.

[aqwut]

Well.. I couldn't get Mike's attention... but The guy at Kershaw's gonna build one out of the dragonplate Carbon FIber for me..... I hope it looks nice... I should be gettin' it in 3 to 4 weeks.... Dragonplate is so beautiful... and so strong....;)
