would belt slippage cause this?

Got a Yardman with 46" deck we use for cleanup and close-in trimming that's not mowing as well as it should.
The blades are OK, and installed right.

We previously found a deck drive (double vertical pulley) with frozen
bearing. Replaced bearing.

There is still a question as to whether the bearing was premature
failure, and, if so, what was cause?

Put new bearing in mower and reassembled deck.

Belt and spindles appear to be running normally.

Not sure about deck belt length being right.

If it was slightly longer than the factory spec belt, could it be
slipping, but not so I could see it by eyeballing? I note the pulley
with new bearing is running very hot. This implies to me that the
belt is slipping, even though it doesn't look like it is.

Does this sound plausible?
