Hybrid Ceramic Ball Bearing Set for Webra 75-91, and other engines

This set is to be used on Helicopter engines :Webra 75/91. please also check your motor specifications, the bearings might fit other engines as well

Those bearings might fit other engines as well

Hybrid 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.

Set include 2 ceramic bearings, Front and Rear

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.

Instructions to use:

Front bearing must have 1 sealing. the inner part must Not have sealing. Sealings are very easy to remove with small screwdriver( wear glasses when working with such tools)

Rear Bearing( larger one) must be without any sealings. please remove if needed.

Hybrid bearings cangive you a feeling of "dry move", but once lubricated, they will be running smooth and almost without friction.
