Kamak GTX Billet Compressor Wheel Technology

Kamak GTX Billet Compressor Wheel Technology

The KAMAK GTX type compressor wheel is made of billet 7075 aluminum. Direct drum assembly offers better performance and durability. Each wheel is cut out of solid aluminum using a 5-axis cnc tool. The length of blades is longer than the Mitsubishi G type.  This results in 15% or greater air flow. The extremely low rotating mass construction means more low and upper end torque.

 All Kamak Center Rotating Assemblies are balanced on the SCHENCK CAB 950 Balance Machine

Schenck Cab 950 high-speed turbocharger core assembly balancer


In this single unit balancing machine design, all components are combined in one rugged housing. Therefore the machine requires very little floor space for installation. The CAB 950 measuring unit with monitor and keyboard is specially designed for high-speed balancing, and integrated in the upper part of the machine. The measured values can be displayed in a vector format or in large, easy-to-read numbers. The vector display shows the exact unbalance reduction ratio achieved in a correction step.

The middle part of the machine accommodates the balancing unit with assembly adapter, surrounded by an enclosure to protect the operator in the even of the bursting of the rotor.

Range of application:

Measurement and correction of unbalance in fully assembled turbochargers. The machine is designed specifically for the requirements of a repair or overhaul facility. However, it is also ideal for cost-effective balancing in a research and development facility.


After installing the core assembly, closing the compressor, cover, and the safety guard, the measuring run can be started. The balance run is quick and easy. After the measuring run, the determined imbalance is shown directly on the monitor with amount and angle. The operator may then carry out the necessary correction by grinding on the compressor nut with a hand grinder. A final check run shows whether the residual unbalance is within the specification or whether a second correction step is necessary.


For each core assembly type a calibration can be easily
performed and stored in the measuring unit CAB 950. First the run-up curve of the core assembly has to be recorded. This curve will show the operator the optimum balancing speed. The calibration data determined is stored in the CAB 950 for future balancing runs – up to 100 files are available for rotor data.
