Purpose-Built Cradle Balancers
MOST BALANCING MACHINES ARE HORIZONTAL
Most balancing machines in the industry are horizontal, or cradle, type machines. The rotor or rotating assembly lies with its axis of rotation parallel to the floor, supported by vertical columns with roller bearings or V-blocks. These universal machines handle both single plane and multi plane balancing, and balance very small rotors to very large. A modular design with extendable bases and multiple drive system options means one platform covers parts from turbines to U-joints, propellers to augers, and centrifugal fans to rotors.
THE PROBAL HORIZONTAL PLATFORM
Every ProBal horizontal machine is hard-bearing and built on the same proven measurement platform. The technology that makes one part fast and repeatable makes them all fast and repeatable.
When a measurement result is ever in question, the operator mounts the included proving rotor in the machine and quickly compares it to confirm the machine's accuracy and calibration.
- Piezo-electric sensors read unbalance in real time, with sample times of approximately 3 seconds.
- Three drive systems: an overhead belt drive (a ProBal exclusive that drives from virtually any surface), a wrap-around belt drive for a broad part-size range, and a direct in-line drive for large parts with no belt-grip area.
- Live encoder feedback displays RPM and correction location as the rotor turns.
- Multi-speed permanent calibration with an included proving rotor. No re-calibration or test weights when you change parts.
- Modular 5-foot extendable bases (auger builds have reached 25 feet) riding on linear rail bearings between the columns and base.
- Fixed and adjustable-height trunnions, with bearing styles from roller bearings to crowned composite V-block inserts.
- Multiple control options: a full-height rolling console, a swing-arm operator panel, or a laptop.
- Windows-based touchscreen ProBal DBS software.
It is our belief that modern hard-bearing horizontal balancing machines should include a verification tool in the same way a precision measurement instrument will have an accompanying standard to measure against.
BUILT TO YOUR PART
Through our proposal process we will review drawings and pictures of your parts and build a machine tailored to your specific process. In the case that custom mandrels or balancing arbors need to be designed and machined we can provide complete packages or design guidelines so that you can keep full control of your own development.
Our experience and long history of working with dynamic balancing systems and numerous applications allows us to provide customized solutions. We work with you from the beginning to understand your specific balancing needs and manufacturing challenges to provide the most comprehensive balancing machine solutions available.

THE PROBAL DBS SOFTWARE
From the home screen, the operator can quickly understand the dynamic condition of the part and apply offsets and compensations to fine-tune the correction strategy, with tolerance-to-industry-standard tools built in.
- Key compensation to cancel the residual unbalance of the drive key or adapter.
- Tooling compensation to subtract the influence of mandrels and fixturing.
- Segmentation for fixed-position correction.
- Drill correction for guided material removal.
- Measurement history for tracking results across parts and runs.
- Balancing reports for documentation and traceability.
Our balancing software is built on a current Windows embedded operating system, which gives your IT department full control over network access and user management.
