Hallo!
Hab eben mal bei Turbonetics auf der seite geschaut,da die jungs ihre Lader mit Keramik-Kugellagern ausstatten und bin fündig geworden! Is zwar auf englisch aber trotzdem zu verstehen denk ich!!!
CERAMIC BALL BEARING
If a turbocharger does not survive, then you can’t win and we won’t stand for that. Traditional turbocharger bearing designs have failed time and time again when the boost pressures are turned up and that is what inspired Turbonetics to develop a bearing design that eliminates any concerns with turbocharger durability in high performance applications.
A turbocharger’s main enemies are thrust and lag. As boost pressures rise, so does the thrust loading on its internal components. This is one of the main causes of a turbo’s failure. As racers began to go quicker and faster they needed larger units to deliver more airflow to the engine. The larger the wheels, the more energy it takes to turn them and thus more turbo lag. Turbonetics utilizes a NASA inspired angular contact ball bearing featuring almost indestructible silicone-nitride ceramic balls. A conventional unit has a capacity of 60-80 lbs. of dynamic thrust load. The patented Turbonetics design can withstand anywhere between 1000 to 2200 lbs. of loading, depending upon the turbocharger model.
The added benefit besides extreme strength is that because the angular contact bearing is the loading surface, it takes half of the exhaust gas energy to drive the turbine wheel. This means that the Ceramic Ball Bearing turbo spools up much faster and provides fantastic transient response when you are on and off the throttle. With Turbonetics Ceramic Ball Bearing units you can build boost faster at the line, reach boost sooner in the rpm band on the street and maintain higher boost in between shifts. Lets talk for a moment about real world performance and how Turbonetics Ceramic Ball Bearing units survive the stresses of high performance street and racing use. Turbonetics uses a single ball bearing instead of two by design! Through extensive computerized modeling and high speed rotor dynamic analysis the floating turbine end bearing was found to be the very best way to absorb and dampen all of the critical frequencies that are transmitted through the turbine shaft as it spins its way to maximum speed. The turbine end bushing style bearing acts as a shock absorber to prevent the destructive rotating imbalances from destroying the turbocharger from the inside out. As a result only the Turbonetics Ceramic Ball Bearing design has no detrimental critical frequencies over their full operating range. No other ball bearing design can make this claim.
Faster response, extreme durability, and unsurpassed quality all combine to make Turbonetics Ceramic Ball Bearing design the standard of performance in the turbocharging industry.
