Q: How do your different RC bearing lines compare to the stock bearings that came pre-installed. How much longer will they last?
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. But 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. As a rule of thumb we would say:
Our Econo Power shielded bearings are comparable to what comes stock with your vehicle, so you should expect the same life as those that you get right out of the box with your car. Because these are shielded bearings they will require maintenance to get a long life. You will want to clean and re-lube them regularly to extend the life or you will have to replace them often.
Our Green Seal & Ultra Seal bearings however are considered maintenance free and lubed for the life of the bearing. You do not have to ever clean or re-lube these bearings at all and they should last at least twice as long as your stock bearings.
And finally our Ceramic Lightning Yellow Seal & Ultra Seal bearings are also considered maintenance free and lubed for the life of the bearing. But because the ceramic ball is so much harder than steel you should expect about 3-4 times the life of your stock bearings.
