Dual Ball Bearing Turbos

These are Garrett's full ball bearing GT series turbos. By design, the GT series represents the latest in high efficiency and broad flow range radial wheel designs. Specially designed blade profiles allow the GT series wheels to out perform the competition in both pressure ratio and flow capabilities. Garrett GT turbos are the standard by which all others are judged.

The cartridge assembly is a Garrett-patented full floating dual row ball bearing configuration. The major benefit of this design is that the mechanical efficiency of the complete rotating assembly is greatly improved by the fully supported ball bearing system, due to substantially lower frictional losses. The result is faster spool up and quicker transient time to boost response. The full ball bearing angular displacement designed cartridge assembly also provides greatly increased thrust load capacity over that of conventional thrust bearing systems. In certain high thrust load long term durability test conditions the full ball bearing system exhibited over three times the thrust load capacity of a conventional bearing system.
