Dynamic Balancing Machines for Turbocharger Core Assemblies (110 MBRS)

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 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.

Pasio series - Horizontal balancing machines for rotors between 5 and 50 kg

The PASIO series from Schenck heralds a new generation of compact balancing machines, in which many of our visions have been realised. The Pasio series enables accurate balancing of a wide range of rotors. Cylindrical rotors with their own shaft journals as well as disc type rotors with intermediate shafts can be balanced simply and accurately. The rotor can weigh up to 50 kg, with a diameter up to 600 mm and a length up to 1100 mm.

Dynamic Balancing Machines for Drive Shafts (HGW)

Horizontal, hard bearing balancing machines series HGW are designed especially for low and high speed balancing of drive shafts. A modular design provides flexibility to change or add components for other balancing tasks such as balancing electric armatures, drums, etc.

Ceno - Crankshaft balancing machine

The CENO is a compact automatic balancing machine for small and medium-sized crankshafts up to a maximum weight of 20 Kg. By means of standardised interfaces, it can easily be integrated into customers’ loading and unloading devices – even as a retrofit. For smaller numbers of parts, the overall concept allows the CENO to be loaded manually without any restrictions.

Wheel assembly lines (130 TBUR)

Automatic assembly and inflation of tubeless tyres in normal, low profile or super low profile type with steel or aluminium rims of various dimensions in batches or in mixed sequence.

Linking of the line, for example, with a preceding valve insertion station and a following wheel balancing machine. Alternatively other assembly and inflation lines for tubed tyres or a mixed operation of tubeless/tubed tyres are also available.

HL series - Horizontal balancing machines for the aircraft industry

Force-measuring, horizontal dynamic balancing machine with permanent calibration and manual operation.

The machine corresponds to SAE machine classification according to SAE ARP 4048: Rotor support in saddle bearings, micr oprocessor controlled measuring unit and optional protective enclosure (protection class B or C) are specifically designed for the balancing tasks of the aircraft industry. They are equipped with end and/or belt drive systems. A large range of accessories is available for expanded range of tasks.

DH series - High speed dynamic balancing and overspeed test facility

For more than 40 years Schenck RoTec has been engaged in the development and design of special high-speed dynamic balancing machines for heavy turbine and generator rotors as well as for high-speed compressors of steam and gas turbines.

 DH bearing pedestals are designed for the following applications:

  • Low speed dynamic balancing
  • Checking of rotor balance at high speeds (operational speed)
  • Dynamic straightening of flexible rotors
  • Testing of material strength by operating rotors at overspeed
  • Rotor investigation in operational bearings

Consulting - Putting theory into practice: Prototypes on the test rig

The moment of truth comes, when the first physical example of your design work is finally complete. Will your assumptions, ideas and calculations turn out to be correct? Will your prototype behave as expected, or will you have to improve certain details?
In our test shop, we can analyse how your rotor or assembly will behave in actual operation. We will provide all the data you need for a comprehensive assessment of your prototype. We will measure and analyse unbalance, eliminate it and conduct a detailed analysis of vibrations, if so desired. These tests will provide valuable information for design and production.

Dynamic Balancing service

This service is ideal if the right balancing machine for a specific job is not available in your company, or if the low quantities involved render the purchase of a balancing machine economically inefficient.

Our dynamic balancing service can also help in research and development when it comes to balancing new rotors or assemblies. Benefit from our vast experience and extensive resources. We will help you to save cost and valuable time.

Field balancing and vibration analysis

The SmartBalancer is a handy instrument for balancing installed rotors fast, accurately and inexpensively without disassembling machines. You can correct rotors of practically any size or weight on one and two levels (i.e., statically and dynamically).
