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 2500 plus degrees F. 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.

The ceramic ball on the right 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.

Upgrade SS Front bearing for Nitro Engine OS 40-50-61-91-105

Upgrade SS Front bearing for Nitro Engine OS 40-50-61-91-105

Upgrade Stainless Steel  Front bearing for Nitro Engine OS 40-50-61-91-105,it fits Also other models, if you not sure, please contact us.

Stainless Steel bearings are made from heat hardened 440C stainless bearing stock.  This steel is hardened to well within the requirements for standard steel bearings.  Since it is a heat hardened stainless, it is magnetic!  It is actually referred to a corrosion resistant steel so tiny rust spots can appear on it but usually not enough to affect performance.  If you had rust issues with standard bearings, these will all but eliminate that problem

Those bearings are a direct upgrade to stock bearing delivered with OS engines. Bearing comes with 2 Rubber Shields/sealings. 1 should be removed in order to allow Oil to pass throw, this side is the Inner side, Outer side stays with Sealing.
