sliding door roller assembly?

[tbkilb01]

found this at toyomotorparts.com. about $10. could this be the rollers assembly with bearings? if it is maybe it will last 20+ years too?

that looks like the top roller

what are you after? the bottom is what goes bad often apparently

I've only had the center rear rollers go bad. Here's a fix: http://www.toyotavantech.com/forum/showthread.php?187-Sliding-door-fix
