Swivel unit SES-4 – more powerful than its little sister SE-4
Swivel unit SES-4 and SE-4: what are the differences?
When analyzing the technical data, it is usually not immediately clear to the observer that the SES-4 rotary actuator is slightly larger, but significantly more powerful than its smaller counterpart.
In each of the 3 spatial dimensions (L x W x H) the SES-4 only requires about 15% more space.
The benefits compared to SE-4:
- 170% of torque
- 3 times the mass moment of inertia is pivotable
- The SES-4 (S stands for strong) is equipped with larger pistons and a 4-point bearing.
| SE-4 | SES4 | |
| Height (mm) | 54.5 | 62 |
| Width (mm) | 42 | 49 |
| Length (mm) | 93 | 107 |
| Volume (mm3) | 212877 | 325066 |
| Mass moment of inertia J (kgcm2) | 110 | 343 |
| Torque (Nm) | 0.94 | 1.6 |
| Piston diameter (mm) | 2x14 | 2x16 |
