As for the RC, the bearings are powered by motor (either electric or engine) and in both ways you cannot vision the friction associated except with the generate heat, the less the friction the less the heat generated and the more the bearing life span, and of course the more the friction the more the heat generated and the less the bearing span, here is the factors that decrease/increase friction.

1- ABEC rating, the more the ABEC rating, the less friction you will get

2- Material of rings/balls/balls retainer, the less friction material will create less friction

3- lubricant usage, the better lubricant the less friction

The SRG Bearing Company has been an innovator in the RC bearing market since 1987. Since then the Boca Bearing name has become synonymous with top of the line, high grade, precision [RC bearings] . Our RC Bearing Catalogs make it very easy for you to locate exactly the bearings you need for your RC Car, Truck, Heli, Engine or Brushless Motor. If you do not see your exact Make & Model listed we are happy to give you an extra discount for getting the informaiton into our database. 

RC Car & truck Orange Seal Ceramic bearing 4 packs 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. The removable, non-contact rubber seals results in a bearing with less drag and that requires less maintenance than a typical shielded iko bearing. The Grade 5 ceramic Si3N4 balls will allow the bearing to be lighter and spin 50% faster than a traditional steel bearing. Each size supplied in two different versions. One with Af2 oil for on road or clean environments and NB2 grease for off road or dirty environments. Free seal replacements are supplied upon request.
