UHF’s splitter-blade design allows it to flow like a larger-diameter wheel without the associated inertia penalty. The result is superior boost response and less power-robbing backpressure.Dual-Row Ball Bearing CartridgeWith silicon nitride ceramic balls, M62 tool steel races, and metallic cages, Xona Rotor’s dual-row ball bearing cartridge ensures robustness to the most extreme operating conditions.Read about Xona’s advanced bearing systems, engineered in cooperation with one of Germany’s most prestigious manufacturers of high-precision rolling-element bearings.CNC-Machined Billet Stainless Steel Center HousingThe workhorse of every Xona Rotor turbocharger is a fully-machined high-strength 17-4PH stainless steel center housing with a true 360-degree water jacket. By fully surrounding the turbine seal ring area with coolant, this center housing enhances durability by preventing piston ring collapse at high temperatures.Dual Piston RingsMost Performance turbochargers today use a single piston ring for sealing the shaft at each end. By contrast, Xona Rotor turbochargers employ twin rings at both the compressor and turbine ends, dramatically reducing oil leakage and gas intrusion. Spreading the sealing load across two rings also slashes wear rates and seal life.Integrated Oil Filter and Modular Oil DrainBuilt into the oil inlet cavity of a Xona Rotor center housing is a large-volume “last ditch” oil filter element. This feature protects the bearing system from oil contaminants, ensuring long bearing life. On the oil discharge side of the center housing is a modular oil drain surface with provision for a variety of bolt spacing configurations.Modular Compressor HousingSeveral compressor housings with different inlet and outlet dimensions allow packaging flexibility to suit the most demanding installations.Check out Xona’s range of compressor housings and frame sizes.
