The old generators that ran 1800 rpm and had big pistons will last longer than the smaller 3600 rpm of similar output mostly due to the speed, but also due to smaller parts having to undergo the same workload that wear faster than the big-ole parts. Nothing you can do about this difference, just know it so you do not compare them.
The Onan 5500 motor runs at 2400 rpm...the generator head is belt drive and turns 3600 rpm
You need to specify which year and model. The OP has a 2008 Model 5500. Runs at 1800 and has NO belt. AND a RV 5500 current does run at 2400 but has no belt also. Doug
