Can You Identify This?

[BIG--T]

I pulled in my garage and seen this underneath my new bike. It is some kind of bearing that measures about 5/16". I have no clue where it  came from. 

Any help will be appreciated.

It's from one of the rollers that rides in the track of your garage door.

Muffler bearing !!! 

[old2soon]

It's from a reverse curve left threaded doomaflotchit.  RIDE SAFE.

pachinko ball?

Has a Harley been parked in your garage? Seriously, the garage door bearing suggestion might be it, however that is a big ball to come from the door rollers. It maybe worth a look at the bearings that hold the shaft for the cables and counter balance spring.

[Jess from VA]

I hate when that happens.

The usual suspect when I find parts in the drive and lawn is a lawnmower part (but I doubt the ball bearing is lawnmower related).

Could it be slingshot ammo?

Check if your pressure cooker is on the shelf...JK
Seriously looks too big for a garage door opener track wheel.

I'm not sure what that is, but Interstates have a lot of extra parts,
so don't worry about it

I wouldn't get any sleep if I worried about all the spare parts that just mysteriously appear on my shop floor. 
Actually Jess beat me, I was wondering about a neighbor kid with a slingshot.

It's a high speed knifilin pin. You get those when you have sand in the wheelbase.

Hey Big-T......... aren't you glad you asked?   

Everybody's a comedian.

I posted up a part pic once, and one guy got it right... a rubber plug on Kury Hwy pegs.

Everybody else was a comedian though.

It's definitely a Ball Bearing and It is bigger than any I have seen on a Valkyrie. If you find any more ,then I would be suspicious about where they came from.

Oh I'm not so sure about that. It could be from anywhere.

Just tossing 1 of those things up at a time from a half a handful will teach the car(s) behind to not get too close next time.

Have any friends that are comedians? I dropped a bolt now and then under a friends Harley, might have taken it too far because he traded it in on a new one. LOL

Where exactly are they located?

[BIG--T]

Yep, Lot of comedians here and I needed a good laugh!  I still have no clue and give up and if I ever figure it out I'll sure post it! It's been a long time since I replaced any bearings and besides, this one had no grease on it but a some wear marks. Since I just  bought it with  only 8k, not knowing any history, I'm suspicious of everything and when I seen the bearing I was freaking out! When I've had these " mysteries on trucks and cars that I couldn't figure out, I just say "well when it comes apart I'll know what it is"! So I guess I'll apply this to the 2 wheeler and hope for the best! 

[tank_post142]

chances are it had nothing to do with the bike ever and just landed there to piss you off. or it might have been picked up in the body work then fell out.

[WamegoRob]

You run a car tire?  Maybe it got stuck in the tread on the road and fell off in your garage.

[BIG--T]

Tank I think you're right and WamegoRob, that woulda been a good guess but no car tire!

[tank_post142]

i carry a hand full in my vest pocket for people who drive too close behind me. but I don't remember being in your garage lately ?

Hahaha! Good idea about tailgaters! I just hope I don't find enough to throw at anybody! 

[Dr Bobs Patient]

It's a terminator metal residual ball.  When ever one of those terminators comes back in time, some of the metallic substances are pulled out from their bodies as a liquid, then doesn't coagulate back into the main body correctly and forms into a ball.  You should be grateful that you weren't around when that SOB came in!

[Jess from VA]

You know, on the off chance it was slingshot ammo, I would be thinking about when the door is/was open, and obvious fields of fire to shoot thru the doorway (like where it came from).  IF you live in suburbia.  And if there were any dings in the back of any cages.

No chance, I live in da sticks!

I had a similar thing happen to me except I found a nut under my bike. I fussed and didn't find out for a few days that it was from my garage door

[Grandpot]

For you NAVY guys, it could be one of the ship's Relative Bearings we kept hearing about.

[Oklahoma_Valk]

Looks to me like your bike might have lost one of its marbles.

Above my garage door is long shaft mounted on the header. At each end of this shaft is a mounting plate with bearings and a hub that wraps the door assist cables on. In the center is another support with a bearing mounted that the torsion spring attaches to, the other end of the long spring attaches to the shaft with set screws. If I remember correctly the center bearings were visible but not as big as the one you found. The new spring has the ball bearings sealed. I wasn't trying to be a comedian. Better tailgator deterrent is .595 solid lead balls.

[SpidyJ]

It is  an Orb of unidentified origin.

sputnik's little brother?

[Jess from VA]

FWIW, I have a little spot in my bike shed where I put nuts, bolts, springs, and other small parts I just happen to find laying around (wondering what the heck that fell off?).  I has grown in size over the years, and every once in a while I find something missing on a machine (like the lawnmower), and guess where I check first.
