Yes, I believe so, in that the typical failure mechanism is the failure of that seal, letting wash water (inherently full of degreasing agents) against the bearing, where it eventually (over perhaps hundreds of wash cycles) washes out enough of the lubrication in the bearing to get steel on steel in the bearing.

From there, the rumble and looseness quickly follows.

The bearings themselves I believe would run for fifty of years in the typical washer duty cycle (~8 hours a week, 400 hours a year, 20,000 hours in a half-decade), if they were running in a typical (non-washing) machine setting.
