Sure, it's some old manco one wheel peel. The bearing I'm talking about is a 5/8 ID X 1-3/8 and it is slides right into the wheel and around the axle, allowing the wheel to spin.Howdy Ross24,
We got's us a bearing guy (Master Hack)
...so, be patient
...& hopefully he will chime in (soon)
...to lay some of his wisdom on ya
But,
Ya might wanna post just a bit more info
...like what kinda kart you have
...& maybe an example of the bearing (in question)![]()
Hey T,Hes looking for bearings on amazon, so probably not. 99502H is a common size, amazon will have those for a couple a bux each. Those are good enough for kart use.
Performance bearings are WAY more money. A ceramic hybrid (high performance, low friction) bearing is $50+ and still not waterproof. There is little in between.
Can you guess the country of origin?noticed that BMI karts has these (~25.00 ea.)
Ceramic High Speed Wheel Bearing
Dimensions: 1 3/8" OD x 5/8" ID
Worst thing you can do to a high speed bearing.you need to jam them full of quality grease
How can grease be bad? Too thick? Explain it, I want to learn!Can you guess the country of origin?
There are so many types of materials, classes of materials, classes of precision within those materials, then classes precision bearings, we could talk about this all week. On the surface it may appear that a bearing is a bearing, but believe me there is more to it than that. Every one has heard of ABEC ratings, that is one classification precision. We could talk about raceway curvature, contact angle, pitchline and a few design considerations. There are still cheap bearings and good bearings and wannabe good bearings.
Worst thing you can do to a high speed bearing.
Sorry, my outlook on this subject is skewed. Been dealing with this s**t too long.
Poor quailty disgusts me.

Hey Denny,How can grease be bad? Too thick? Explain it, I want to learn!
Understood, thats why I said use the $2 amazon bearings and keep em dry.Your average go karter isn't very interested in ~$200.00 bearings
...even if they are super high quality
The simple explaination is it traps heat. Yak grease makes it even worse. If you want more:How can grease be bad? Too thick? Explain it, I want to learn!
Good guess, there are several reasons. What you are referring to is ball skidding. 'nuff on that!I figured it was more like the rollers would not spin or something like that.
Sounds painful!Good guess, there are several reasons. What you are referring to is ball skidding. 'nuff on that!
Guys, how do I take care of these bearings? I feel like no matter I do, they just go bad. On the drive wheel itself, I go through so many bearings I gotta be doing something wrong.
That's a common symptom of having the chain too tightWhat's funny is I have yet to replace any bearings except for the ones on the drive wheel.

I've been keeping them dry, but still have to replace them like all the time. What's funny is I have yet to replace any bearings except for the ones on the drive wheel.
Also, what's the difference between "99502H-NR" and "99502H"?
In the typical diagnostic "If- Then" scenario the first, simplest, most logical conclusion is the chain being way too tight.Sounds like the bearing is too small for the application.
99502 is a .625 bore size. On a one wheel peel?
how many are in that hub?
how much power is going through it?
what is the vehicle weight?
