SGB Series
Horizontal Soft Type Balancing Machine (Two-Plane)
 
 |
Ideal for precisely measuring two-plane imbalances in small workpieces
Shimadzu SGB 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
| (1) |
Standard machines include one standard bearing.
Cost estimates for special bearings are available on request. |
| (2) |
The minimal achievable residual unbalance will
vary with the workpiece weight and the test speed. Refer to
the attached sensitivity diagram for details. |
| (3) |
Depending on the form and weight of the workpiece,
the test speed may be increased beyond the specified range. |
| (4) |
Upward-tangential drive systems are available
on request. |
