Im useing an ev warrior running at 18v for my weapon motor the weapon is a 2kg spinning bar 1-2 reduction belt drive i am thinking of useing these



On the weapon would they be strong enoughf or not?
They have a 15mm bore and pressed steel housings.

nick, jake or andrew might want to comment before i, but 15mm would be strong enough.

that pressed steel housing may be a worry, it looks thin. check out what happens when spinners get into that pressed steel stuff (check out the pic of my castor in my personal album)

Im not worry about other spinners attacking them i just want to know if they will strong enoughf to run my spinner.

And where is your personal album?

no i meant the housings may deform under the force of your own spinner.

but i think youd be right.

and if you go into the photos section, then click the 'users personal galleries' button, mine will be there.

That was a castor!!!

ANY sugestions on bearing for spinners that i can get in a 15mm bore and they are light weight?

the bearing is only half the problem
you ave to mount the bearing
and transmit that load through your bot

Annihilation has a 22mm bearing mounted in a pressed steel mounting. which is then bolted and arildyted onto the motor.

Why are all my bearings 15mm and i mcant find 15mm steel bar only 16mm

I was told at the shop 15mm was a standard size shaft meaning its easy to find 15mm bar.

Damn them

Its turning out a bit too expensive then after i got collars put on my 16mm bores on my sprockets to make em 15mm as it was too much work to screw aroung with the bearings

with the planned gear reduction. U do not need a 2:1. u drop speed and kinetic energy stored up in the bar. A 1:1 belt drive ratio would work much better. Still a fast spin up time and awesome speed of weopon.

Motorcycle wheel bearings for me.

I think now i will be running my bot at 24v so the ev will be running at 4500 rpm if i dont gear it down?

is there any way to mount a normal bearing (with no flanges) in a flat plate without special bearing blocks etc?

i just have these two 16mm bearings and would like to actually use them sometime this decade....

the plate i want to mount it in is 7mm thick steel and i want them mounted horizontally.
