Expand rar archive on Mac OSX

I’ve downloaded a collection of files on RS, all .rar archives.
I used UnRarX to extract them which leaves the .r01, 02, 03 etc files… I try extract these with UnRarX and get unknown errors, I get the same with the StuffIt Expander. I’d suspect it’s a problem with the archive(s) but nobody else has had a problem with it…
What software would you recommend?
