Boca Bearings RC Newsletter: Issue 9

One of the most essential performance items on your RC car can't even be seen with body off. I refer to the bearings hidden away in the drive train. With proper care and maintenance, bearings will last a very long time and offer excellent performance throughout their lifetimes.

Ceramic Orange Seal Abec 7 Bearings
#05-220C-OS NB2

RC Car & Truck Orange/Yellow Seal Ceramic bearing kits are the true secret weapon for serious RC racers. ABEC #7 tolerances makes the Orange/Yellow Seal line the closest precision tolerance that Boca Bearings has to offer. The removable, non-contact rubber seals results in a bearing with less drag and that requires less maintenance than a typical shielded bearing. The Grade 5 ceramic Si3N4 balls will allow the bearing to be lighter and spin 50% faster than a traditional steel bearing. Free seal replacements are supplied upon request...more

Q: How do I remove my shields or seals?

A: For fixed metal shields you should use an awl. Place the awl on the shield toward the outer race. Punch down lightly until you make a small hole. Then peel the shield back with the awl. Removable metal shields are held in place with a retaining ring. Run a sewing needle along the inside of the outer race to pop out the retainer. Once the retainer is removed the shield should pop out with a light tap. To remove a rubber seal use a pen knife or sharp pointed object. In most cases the rubber cannot be re-used.
