Versatile horizontal balancing for various rotor types
Lightweight balancing machine 9A714 is used to balance rotors of various designs, the mass of which does not exceed 60 kg. The high sensitivity of the machine allows you to work with unbalances of very small magnitudes.
This series of machines has many innovative technical solutions that make balancing simple and accessible to anyone. The machines have high performance and functionality, which makes them in demand in manufacture in various industries.
All machines of this series have a high accuracy of determining imbalance – 0.4 g ∙ mm / kg, (by special order 0.1 g ∙ mm / kg can be made). This accuracy is a combination of many factors, including the merit of machine design features:
Special features of this machine include very narrow supports (42 mm support width), which allows balancing of complex configuration parts such as crankshafts of cars, ship and railway turbochargers, turbochargers of cogeneration plants, etc. At the same time, these machines can be used for other simpler parts in terms of configuration such as electric motor rotors, all sorts of fans. This machine is also often used for balancing wood-cutting tools during their production.

Support and Mechanical Structure Design
- Dual support configuration capability – Interchangeable roller and prism support systems provide optimal mounting solutions for diverse rotor geometries across the extended weight range up to 60kg. The dual configuration approach accommodates both bearing-mounted and shaft-type components from lightweight to medium-weight industrial applications.
- Quick-change roller-to-prism conversion – Support design enables rapid replacement of roller units with prism units to minimize changeover time between different rotor types across the broad weight spectrum. This modular approach maximizes machine utilization efficiency in production environments handling significantly varied rotor sizes.
- Enhanced roller accessibility design – Support geometry provides excellent access to roller assemblies for rapid rotor installation and removal operations across the extended weight range.
- Adjustable support height mechanism – Variable height system accommodates rotor bearing journals from 20-100mm diameter with precise centering capability for components across the 0.6-60kg range. The adjustment range enables setup flexibility for precision components through medium-sized industrial assemblies.
- Extended drive neck accommodation – Support design accommodates rotor drive necks up to 300mm diameter, significantly larger than bearing journals, enabling diverse drive connection methods. This capability provides flexibility for components with specialized drive requirements or oversized coupling areas.
- Minimal to extended center distance capability – Support design accommodates rotors with distances between bearing journals from 20mm minimum up to 700mm maximum. This range enables balancing from compact precision components to substantial medium-weight assemblies.
- Extended monolithic support and base construction – Integrated framework with enhanced length (1100mm base) minimizes oscillation system elements while providing extended workspace for medium-weight rotor measurement. This structural design ensures consistent accuracy across the 0.6-60kg extended capacity range.
- Foundation-independent installation design – Self-contained structural design eliminates special foundation requirements, enabling installation on standard concrete floors despite extended capacity. This design characteristic reduces installation costs and enables flexible machine placement in diverse production environments.
Enhanced Capacity Drive System
- Optimized frequency-controlled asynchronous drive – 0.75kW electric motor with enhanced torque characteristics for the extended 0.6-60kg rotor range while maintaining efficient power consumption. Frequency inverter provides smooth speed control across 200-2000 rpm range with infinitely variable adjustment capability for diverse medium-weight applications.
- Advanced belt tensioning repeatability system – Belt drive mechanism incorporates micro-tuning function for precise belt tension adjustment across the extended weight range with exceptional repeatability. This design feature ensures consistent rotational characteristics from lightweight precision components to medium-weight industrial rotors.
- Variable belt tension micro-adjustment – Integrated micro-tuning capability allows fine adjustment of belt tension forces to optimize drive characteristics for the broad rotor weight spectrum up to 60kg. The adjustment system maintains measurement precision across diverse rotor types and significantly varying weights.
