Product InformationXona Rotor has implemented innovative features in its XR line of performance turbochargers to enhance performance and durability. Among them is Xona’s proprietary variable-preload ball bearing cartridge system. Traditional bearing systems with insufficient preload can experience ball sliding and scuffing at high shaft speeds, leading to fretting of the bearing races and short bearing life.
The bearing housing itself is a fully-machined, high-strength stainless steel component with an extended water jacket. By fully surrounding the turbine seal ring land area, this advanced cooling feature combats heat soakback, preventing piston ring collapse for enhanced durability at high temperatures.
Xona XR turbochargers use hybrid (ceramic balls and steel races) ABEC 7 angular contact ball bearings made with M62 powder metal steel races, silicon nitride ceramic balls and metallic ball cages, delivering significantly elevated robustness and durability at extreme temperatures.
Xona XR turbochargers employ twin piston rings at both the compressor and turbine ends, dramatically reducing oil leakage and gas intrusion. Large-diameter oil slingers at both ends of the shaft provide further protection.
At the oil inlet, XR turbochargers offer a choice of 7/16" inverted flare or straight M12x1.25 connections. A large-volume “last ditch” oil filter element prevents oil contaminants from entering the bearing system. A modular oil drain flange allows for a variety of bolt spacing.
