These rollers see a lot of use and tend to wear as a group, so when one's had it the rest usually aren't far behind. The catalog shows this part appearing across a long production run, which tells you it's a basic wear item that stuck around in the parts books for a long time rather than something that changed much.
Worth checking the full roller set in your clutch when you're in there for other work, since replacing one at a time when they're all the same age doesn't make much sense. Give us a call if you're not sure how many your clutch takes.
