The timing makes me suspicious of the preload not being set correctly on reassemble after inspection or grease compatibility issues.

When shown the "broken" bearings, was it the rollers, cages or races that were broken? Or where they just a mangled mess? Knowing which component failed and how can help guide you to the cause.

Here is some insights:
