Stainless Steel Abec-5 Si3N4 Hybrid Ceramic Ball Bearing 5x13x4 #695ZZ/C
Description
Those bearings are ABEC-5 standards, and perfect for All motors/engine applications, we use them as Upgrade-tuning to make the engine long life lasting. Those bearing size might fit other engines as well Ceramic is the new Holy Grail! Its lighter, smoother, stiffer, harder, corrosion resistant, and electrically resistant. These fundamental characteristics allow for a wide range of performance enhancements in bearings. Ceramic bearings dissipate heat quickly, reducing friction and wear while maintaining a precision smooth surface. Today's leading edge ceramics are made with Silicon Nitride (Si3N4) and have characteristics similar to the heat absorbing, highly resilient tiles on the Space Shuttle as they protect it from the 1000C, extremes of re-entry into the earth's atmosphere. The use of Ceramics for bearing components results in a far superior product over traditional all steel ball bearings. Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si. 3N. 4 (Trisilicon tetranitride) is the most thermodynamically stable and commercially important of the silicon nitrides, and the term ″Silicon nitride″ commonly refers to this specific composition The ceramic ball on is not only much lighter and impervious to corrosion, but also much more resistant to impact. Ceramic bearings earn their reduced friction due to much tighter roundness tolerances as compared to even the best steel bearings. Hybrid bearings can give you a feeling of "dry move", but once lubricated, they will be running smooth and almost without friction. |
