I swapped my 700MX bearings for Boca Orange Seal Ceramic bearings right away. I wanted to run Align motors, but listened to the feedback here on RR on early bearing issues. So I went Boca from the start.
I took some pictures to show the process in case anyone wants to do bearings and was apprehensive about the process.

Unfortunately, there is never an explicit warranty with bearings. Bearings do eventually wear out and every application, setup and operator is different. It is very difficult to calculate life expectancy without having extremely detailed data about your application. However, Boca Bearings has been in business since 1987 and we stand behind our product 100%. We will always replace or exchange any bearings that we determine to have failed prematurely.
