Probably has needlle bearings not ball bearings,not good for longevity,light though,good luck!

They can have both types of bearings. Most gassers will have ball bearings on the crank and needle bearings on the connecting rod.

I've seen a Mac saw that had needle bearings on the crank. Those usually do fine if you put a bronze thrust washer inside the case.

so does that mean it will probably burn up

no, they're just saying that if it has roller bearings instead of ball bearings, that you should put a thrust washer on the crankshaft between the front crankbearing and the crankshaft, if it has ball bearings, it's all good
