Re: Sealed bearings - service life
I can't speak from a service standpoint, but since I do work for a bearing mfgr, and one that makes bearings in these sizes, I can tell you ther are minimum standards. Most well exceed these, but some just meet them. From a durability standpoint, they could last 30K miles or 3 million miles. It just depends on the individual bearing, how clean is is before grease & seal (or shield), handling, and installation. Just dropping a bearing can cause spalling, and you won't know it except for pre-mature failure. Meaning, if the person installing the bearing at the factory drops it, & picks up back up & installs it, he just installed a latent defect caused by handling.
Maybe some else here can speak about wear from experience, especially someone who services them.
