Looks like you don’t have a spacer in between the bearings my friend. If you don’t use a spacer then the bearings will tighten up on the cores and wreck them.
As I wrote in the post I do have spacers and washers in all wheels
Apologies for speed reading.
Then I would say that the distance between the bearings seats on the cores is not standard and the spacers are not doing their job. Cheap wheels.
Probably. But how can Turnigy sell this as a set when it breaks doing what it’s is meant to do?
Do you use the axle nut to screw the bearings down into the wheels, or do you press them in by hand and then bolt everything together?
I used the axle nuts to press the bearings into the wheel.
do you have a ring washer between the wheel and truck and between the wheel and nut?
Yeah, they can be seen in the third picture with the spacer @mynamesmatt
is there any oil or grease in there? maybe clean em out with wd40 and then fill them up with grease and try again?
No, they’re only about a week old, and it was the third time riding the board. So everything should work except it doesn’t.
If the bearings are really cheap, like I suspect, then they probably got tiny pits in the inner and outer rings from the ball bearings pressing into them.
And if that caused excess drag, then it could heat things up and make the bearing slip in the wheel, or possibly melt it just from the heat.
Make sure the belt is not over tight.
Ok, thank you. So you don’t think it’s just the wheels that are cheap because they are partially made of plastic? I just don’t understand why Turnigy would make a skateboard kit with bearings that break when you use them for the exact purpose they are made for (Or sold for).
I will try that, thank you.
I’ve definitely messed up my fair share of bearings from not pressing them in by hand. I doubt it’s the wheel, it shouldn’t melt that easy…
Are these your front or rear wheels that keep breaking?
Sorry I forgot to mention that. Both times it was the pulley wheel. @TowerCrisis
I’d also check if your belt is too tight… that could cause problems, although I’ve never seen it cause wheel failiure before
I also suspect that could be the issue, as I remember it being pretty tight.
Post a picture of the whole assembly when you put it back together. It might give us some clues. This is a WEIRD part failure that I don’t think any of us have seen before
