These Modify 8mm Ceramic bearings are much harder than steel bearings. These ball bearings fit in the King Arms 8mm bearing gearbox , as well as some other AEG gearboxes.
Ceramic balls are over 100% harder than steel balls. In a hybridbearing, the extremely hard and smooth Ceramic Ball keeps racewaysclear of contaminants by pushing them away from the contact patch. Inaddition, the ceramic ball remains extremely smooth, preventing ball torace damage. For the end user, this means reduced bearing wear andlonger bearing life at high precision.
* Vickers Hardness 10 KG Load: Ceramic = 1550, Steel = 730
