Ideal for precisely measuring two-plane imbalances in small workpieces
Shimadzu SGB/STB series dynamic balancing machines offer outstanding precision, reliability and ease of use. They are widely used on production lines to balance small rotating parts. These two-plane balancing machine models are small enough to be used on a tabletop.
Features
- High-sensitivity - designed for small workpieces.
- Capable of balancing workpieces from 0.001 kg to 30 kg (series includes six models for different weight requirements).
- Sensitivity is calibrated using actual workpieces, resulting in extremely small error levels at full-scale, and highly precise plane separation.
- Moving coil pickups ensure high signal-to-noise ratios.

Typical Applications
Small motors, small rotors, fans, hard disk drives, high speed rotating polygon mirrors, and rotating parts in general
- Standard machines include one standard bearing. Cost estimates for special bearings are available on request.
- The minimal achievable residual unbalance will vary with the workpiece weight and the test speed.Refer to the attached sensitivity diagram for details.
- Depending on the form and weight of the workpiece, the test speed may be increased beyond the specified range.
- Upward-tangential drive systems are available on request.
