Boca Bearings RC Newsletter: Issue 5

A product introduction for bearings? Any RC car & truck model has bearings what's so special? Especially in competitions engines and controllers are dictated and leave little room for improvements.Therefore good quality bearings are even more important. It's not just the weight of the bearings, but also the seals and shields that protect from dirt that are significant.

To be honest, I have never had been this skeptical before any other test. I am testing the ceramic bearings with rubber seal. Because I have been a skeptic about the effectiveness of the bearings I've decided to build a ramp and let my Hotbodies TCX roll-out without any electrical power with my stock bearings.

RC Car & Truck Orange Seal Ceramic bearing kits are the true secret weapon for serious RC racers. ABEC #7 tolerances makes the Orange Seal line the closest precision tolerance that Boca Bearings has to offer.

Q: What kind of maintenance do sealed bearings require?

A: All of our sealed bearings are considered maintenance free and lubed for the life of the bearing. This is because they are packed with a heavy duty, lithium based grease. When the lube fully dissipates it is generally time to replace the bearing. However this does not mean that you cannot extend the life of the bearing. When they start to feel gritty you can remove the seals and soak the bearings in our Clean Touch over night. Then you can re-lube them with your lube of choice. Just keep in mind that the thinner the lube is, such as oil vs. grease, the quicker it will dissipate and need to be reapplied.
