Description

Ceramic Hybrid, ultra sealed bearings are specially designed for use with electric motor, RC vehicles but can be used in almost any application. The Ultra Seal is a non-contact, frictionless seal that is placed beneath the metal shields so they are still considered maintenance free and lubed for the life of the bearing. These bearings have ceramic balls, with stainless steel races and retainers. Ceramic hybrids are lighter, capable of achieving higher RPMÆs and sustaining higher operating temperatures than traditional bearings. Bearings that are packed in grease will require a short break in period to loosen up. Grease can usually be removed before shipping upon request. ABEC #3, (8X14X4)MM

    Had 4 flights so far with these very fancy (& expensive) brgs & they are exactly what I expected from Boca's!
    Very briefly:
    1/ Could never eliminate a visually noticeable canopy vibration when hovering in close proximity
    2/ The heli never really sounded sweet as in nice to listen to.
    First time into a hover & I said to myself "This is finally starting to sound like a well tuned & set up engine! The aircraft just sounds so much better & I reckon it even flies/behaves just that little bit better now! Sounds so sweet . To someone who used to race single seater race cars in an earlier life (& did all his own preparation)...this is music to ones ears !!!!!!!!!!!!!!
