Description

Ceramic Hybrid Axle Bearings for your Racing Kart
These bearings are made with all the top componentry;
#52100 Chrome Steel Races,  Si3N4 Ceramic Balls,
Injection Molded Polyamide Cage,  Rubber seals,  C3 Clearance and built to P6 Precision
.
These are SB Style Insert Bearings; t
hey have an inner ring that is flush on one side.
These bearings feature Silicon Nitride (Si3N4) Ceramic Balls that are non-porous, non-magnetic, non corrosive and lighter than steel.
They're also harder than steel and virtually friction-less ... they will spin faster than steel balls.
the listing is priced per bearing ..
the picture shows three bearings so you can see the three different sizes that are available,
but please note you are buying the bearings by the 'each' ..
you'll most likely want two bearings for your kart, be sure to select qty 2 when you place your order.
Bonus :  all size bearings now come with an extra set of seals   :-)
Why Ceramic Hybrid Bearings ?
Si3N4 Silicon Nitride Balls are of the highest quality available for bearing performance. They have an extremely hard and smooth surface
.. over 2x harder than steel and 4x smoother (just 1/4 the friction coefficient of steel)  and all at about 1/2 the weight ; much better than steel balls!
Si3N4 Silicon Nitride Balls will not crack or 'micro-weld' like steel balls, they actually are so smooth, they polish the races as they roll, very cool (and smooth)
Si3N4 Silicon Nitride Balls won’t corrode or pick up / micro-weld to any particles that enter the bearing. If the races become pitted or damaged by dirt that enters the bearing, the Si3N4 Silicon Nitride Balls will actually polish the races smooth again.
Si3N4 Silicon Nitride Balls reduce friction because they are rounder and smoother than steel balls. Si3N4 Silicon Nitride Balls are much more precise, run at lower temperatures, and vibrate less .. they actually become smoother with use.
Please note:
Ceramic Hybrid Bearings require a short break in period to 'settle in' the rubber seals and achieve their full 'free spinning'  efficiency....  just a hand full of 'hot laps' around your track will do it
do your 'google' .. learn more - ceramic hybrid bearings are the only way to go if you are seriously looking for that racing edge.
