Question about round baler lifespan

Thinking about how long a round baler can be expected to last before its “wore out”, am I wrong in thinking that all else being equal, a baler that has made more bales per hour over its operating life will have more bales on it before its wore out?  My view is that since a round baler is constantly turning the crop in the chamber, there is wear in the chamber and to the driveline all the time it is running.  In other words, round baler wear is as much a time factor as it is a bale count factor.  I wouldn’t expect that a baler that averaged one bale per minute is going to last twice as long as one that made a bale every two minutes, but there has to some benefit in more bales per hour?
