I’m writing here because I am having a problem with my newly build electric skateboard. The problem is that the bearings keep melting the bearing hub of the wheel, this has happened two times and I am clueless about what is causing this. The wheels that I am using is the ones I got in the Turnigy skateboard conversion kit, I am thinking it might be the wheels that is just badly designed as some of the bearing hub is made of plastic but as I said I am not really sure what is causing the issue here. Also the second time it happened the bearings broke into five pieces. Also I do have washers and spacers in all wheels, so I don’t think that is what’s causing the issue. I could really use some help as this is really frustrating and I am clueless about what to do and what to buy.
Here are some images of the first time it happened:
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.
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.
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.
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).
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
