Ultimate precision for high-speed applications

SBR-10 machine is a professional special equipment for high-speed balancing of assembled cartridges. It is ideal for repair workshops specializing in turbocharger reconditioning. It solves a wide range of tasks that service stations face on a daily basis. The SBR-10 has a universal mounting system for any cartridge weighing up to 9 kg. The equipment is highly productive and is used not only in workshops, but also in production facilities with serial production of turbochargers. The balancing machine stops automatically at an unacceptable vibration value, which prevents destruction of the cartridge even if mistakes are made during assembly. This feature and the triple degree of oil cleaning make it the safest of its kind.    

The tasks it solves:

  • high-speed modal balancing of cartridges (up to 300,000 rpm).
  • vibration testing of assembled cartridges (from 0,2 to 10 G).
  • Running-in of cartridges after assembly at operating speeds;
  • checking the cartridges for oil leakage.
  • assembly quality control (report generation and printing).
The balancing machine is equipped with an oil station with hydraulic pump for quality testing and cartridge part preservation. A highly sensitive suspension determines the position and unbalance of the shaft at operating speeds (80,000 to 300,000 rpm). The turbocharger is accelerated to operating speeds by compressed air through the pneumatic system.

  • Balancing of cartridges up to 9 kg in safe conditions as the hydraulic system supplies heated oil (from 40 to 65 ° C) under pressure (1-4 bar) to the cartridge creating a ” lubricating wedge ” that protects the parts from wear and tear at high speed.
  • Elimination of unbalance without removing the cartridge from the stand, eliminating the need to reset it due to the triple degree of cleaning oil, eliminating ingress of chips and particles into the cartridge.
  • High quality repair without risks. The bench is equipped with an auto-stop system in case of a high vibration level, which prevents a poorly assembled cartridge from destroying itself on the bench.
  • The alarm system, pressure gauges and temperature relay allow for an immediate assessment of the condition of all the support systems of the bench.
  • The well-thought-out design of the enclosure provides free access to any component or unit of the bench, as well as guarantees comfortable and safe work of the operator in the working area.
  • Balancing of the turbocharger at rated speeds corresponding to the requirements of the European standard ISO 11342:1994.
  • A wide database with the possibility of its self-renewal will allow the bench to remain up-to-date for 10 years.
  • Display of graphs of the previous measurement enables quick assessment of the efficiency of the unbalance correction, simplifying the analysis of the graphs.
  • Display of phase, vibration acceleration, speed and tolerance in digital and graphical formats makes balancing easier and allows you to quickly master the operation of the balancing system without special training.
  • Balance reports are stored in the computer, containing results, date, time, turbine type and job order number. They can be printed on the printer to confirm the quality of the assembly and balance.
  • Safe operation of the machine is ensured in accordance with the requirements of EN ISO 12100.
Ultra-High-Speed Turbocharger Engineering
  • Operational speed simulation – Engineered to balance turbochargers at maximum operational speeds up to 300,000 rpm, replicating exact operating conditions encountered in automotive applications. This capability enables elimination of dynamic deflection effects that only manifest at operating speeds, ensuring guaranteed repair quality and turbocharger performance reliability.

Your questions — our technical solutions

The SBR-10 machine is designed for the final stage—high-speed balancing (VSR) and testing of the assembled cartridge. Unlike low-frequency test benches, the SBR-10 simulates the actual operating conditions of a turbine in a vehicle, allowing for the elimination of dynamic shaft deflection and minute vibrations that only manifest at ultra-high speeds.

Yes. With a load capacity of up to 9 kg, this machine is highly versatile. Its design and the specifications of its acceleration system allow it to perform final balancing not only for passenger cars but also for most commercial vehicle turbochargers, ensuring they achieve their factory-rated service life.
The only requirement is an air receiver with a capacity of 1.5 cubic meters or more.

The SBR-10 pneumatic drive system is capable of accelerating the rotor up to 300,000 rpm, depending on the cartridge size. This rotational speed is necessary for balancing modern compact turbines operating at their maximum capacity.

The hydraulic system in the SBR-10 is essential to the cartridge’s operation:

  • Simulation of engine operation: The supply of oil under pressure and at operating temperature creates an oil wedge; without it, rotation at speeds of up to 300,000 rpm would result in the immediate failure of the bearings.
  • Leak testing: In parallel with balancing, the machine allows for verification of seal integrity under dynamic conditions—an optional feature is available.

No. Special adapters and universal nozzles, which are included with the machine, are used to install the cartridge. This allows for minimal air consumption from the air receiver during testing.
Changing the adapter takes very little time, which is critical when dealing with a wide range of turbochargers.
