Precision Balancing for Every Rotor Type
Industrial Dynamic Balancing Machines for Workshops and Production
Raney Machine Tools supplies hard bearing dynamic balancing machines in three configurations: vertical single-plane for disc-type components (flywheels, clutch plates, impellers), horizontal end-drive for shaft-type rotors (motor armatures, crankshafts, pump rotors), and horizontal belt-drive for rotors where end drive is impractical. Rotor capacities range from 0.3 kg to 10,000 kg across 25 models.
Every balancing machine features a DSP-based processor system with 150 MHz high-speed measurement. The system measures unbalance in grams with angular position, auto-calibrates with a single keystroke, and provides tolerance indication for both correction planes. Machines conform to IS:13277, ISO:2953, and ISO:21940 standards. Minimum achievable unbalance is 0.5 microns (gmm/kg) across all models.
0.5 Micron Achievable Accuracy
All models achieve 0.5 microns (gmm/kg) minimum unbalance for maximum rotor weight. 95% unbalance reduction ratio on horizontal machines. Auto-ranging from 0.1 grams up to kilograms with ±1 RPM resolution.
DSP-Based 150 MHz Measurement
High-speed DSP processor with auto calibration, RS232 serial interface, adjustable auto cycle, and auto tolerance indication. Compact design with less than 50 watts power consumption. No external hardware required.

Common Questions
Frequently Asked Questions
Common questions on vertical vs horizontal balancing, DSP measurement systems, and rotor weight capacities.
We supply three types: vertical dynamic balancing machines (7 models, 3 kg to 300 kg rotor capacity) for disc-type components, horizontal end-drive balancing machines (10 models, 10 kg to 10,000 kg) for shaft-type rotors, and horizontal belt-drive balancing machines (8 models, 10 kg to 3,000 kg) for rotors where end drive is impractical. 25 models in total.
Vertical balancing machines perform single-plane balancing on disc-type components: flywheels, clutch plates, impellers, and fan blades. The rotor sits flat and spins on a vertical axis. Horizontal balancing machines perform two-plane balancing on shaft-type rotors: motor armatures, crankshafts, pump rotors, and rolls. The rotor sits on bearing supports and spins on a horizontal axis.
All 25 models achieve a minimum unbalance of 0.5 microns (gmm/kg) at maximum rotor weight. The DSP-based 150 MHz measurement system auto-ranges from 0.1 grams up to kilograms with +/-1 RPM resolution. Horizontal machines achieve 95% unbalance reduction ratio per correction cycle.
Choose belt-drive when end drive is impractical: when the rotor has no shaft feature to couple to, when you balance a wide variety of rotor shapes that would each need a custom adapter, or when the rotor geometry makes end-drive coupling difficult. Typical belt-drive applications include pipes, printing machine rolls, and components where direct coupling is not feasible.
All our balancing machines conform to IS:13277, ISO:2953, and ISO:21940 standards for balancing machine performance and safety. These standards define permissible residual unbalance, measurement accuracy, and machine classification.
Yes. Vertical balancing machines can be fitted with a drilling head or milling attachment for correction on the same machine, eliminating the need to un-clamp, correct on a separate machine, and re-clamp for re-measurement. This single-position operation speeds up the balancing cycle significantly.
The DSP processor panel features 150 MHz high-speed measurement, auto calibration with a single keystroke, RS232 serial interface for data logging, auto-ranging from 0.1 grams to kilograms, auto tolerance indication in grams and gmm, RPM indicator with +/-1 RPM resolution, and adjustable auto cycle. Power consumption is under 50 watts. No external hardware is required.
