No. There isn't a maximum. Right now, workload for SP's is once every five games they'll start. In those starts, they'll usually be capped to 100 pitches per game.
Same thing for RP's. They aren't capped. They can throw every day. Usually after throwing 2 or 3 games in a row, they'll receive 1 or 2 days of rest without throwing. They'll throw about 70 innings in a year. 25-40 pitches per game is what is typical for relievers. They're usually capped to 1-2 innings per game.
This is because throwing overhand is not natural and unhealthy for the rotator cuff. Throwing underhand is healthier, but much more ineffective. Because the guys throw overhand, they put a lot more wear and tear on their shoulders and elbows. Which is precisely why we've arrived at these workloads in modern day baseball.
