got an S Series motor that needs a new shaft, this the one with the woodruff key slot on it?

that's the right one. The 201616-001 is a 1-inch straight keyed shaft with a Woodruff key slot, built specifically for S Series applications. It's an Eaton Char-Lynn spare part, so it's a direct fit for that motor family rather than an aftermarket substitute.
