Cartridges (Coreassy)

Description

The complete central body, also called “cartridge” or “coreassy” represents the central unit of the turbocharger. It is the moving part where the components interact dynamically taking energy from the exhaust gases and then transforming them into a rotation movement which will be used to suck and compress air inside the engine. All that increase the capacity of the power engine. Apparently, it seems a simple component but in the reality, it is incredibly sophisticated and complex. The most important features of a cartridge are those that can not be correctly perceived and evaluated by eye. The most important are the quality of the work surfaces, the materials, the construction and heat treatments tolerances. Until the cartridges were only original (genuine) there was no doubt about their quality but today there are many non-original products in the market whose quality is often unknown. The cartridges of the present-day turbochargers seem equal to those of the past but it is not so. In fact, in the last 30 years the technological evolution of this simple product has been impressive. The most striking aspect is the rotation speed obviously linked to the type of materials, the compressor wheel shape and the balancing. The actual values in small rotators exceed the 200,000 rpm, an unthinkable value to reach. It is required a perfect balancing and good quality of materials. To install non-original cartridges generates a great risk both for the mechanic and for the final customer. The turbocharger breaks can involve other mechanical parts. The quality is the keyword.

SAITO markets new genuine coreassy, the maximum expression of the quality available on the market and guarantee of long life, and for some applications offers not original cartridges but 100% controlled before the sale in every detail, including balancing.
