Is it okay to run 1/2" wire rope through this block even though the sheave size shows it is for larger 5/8" - 3/4" wire rope?

There is some debate on this. Some would argue yes it's fine, others would say it depends on how much load is being applied, the speed of line, etc. When you run wire rope in an oversized sheave, you can get flattening of the wire rope due to lack of sidewall support, and that can lead to premature line failure.
