Airtac SED Double Rod Cylinder SED32X155S
The AirTAC Airtac SED Double Rod Cylinder SED32X155S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø12mm piston rod exits BOTH ends of the Ø32mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 155mm, PT1/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED32X155S
The AirTAC SED32X155S is a double-acting, double-rod profile cylinder machined to the ISO 15552 / VDMA 24562 dimensional standard. Because a 12 mm rod exits both end covers, the annular piston area is identical on extension and retraction. This yields exactly 345 N of output force in both directions at 0.5 MPa, rising to 483 N at 0.7 MPa.
The integrated -S magnet allows position detection via CMSE reed or DMSE electronic sensors. The extruded aluminum barrel lacks external tie rods, and the rear rod end can drive a secondary mechanism or carry a cam, while field-adjustable air cushioning at both ends manages end-of-stroke deceleration.

| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C (0–150 °C with FKM seals) |
| Speed range | 30 – 800 mm/s |

Specifications follow the official AirTAC SED datasheet and ISO 15552 / VDMA 24562 dimensions. Confirm against the product label before installation. Port options: PT (standard) / G (BSPP).
Theoretical Output Force (Ø32mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 kgf |
Because a rod exits both ends, the effective piston area — and therefore the force — is identical on extend and retract. Actual usable force is lower than theoretical; size with a safety margin.

Where the Airtac SED Double Rod Cylinder SED32X155S Is Used
Pick-and-Place Transfer
Drives lightweight electronic component handlers. The twin 12 mm rods prevent jaw rotation during 155 mm transfers, maintaining 345 N of precise equal force both ways.
Web Edge Guide
Actuates a paper or film steering roller. The rear rod end mounts a cam follower, while the front rod provides 483 N of guiding force at 0.7 MPa without directional asymmetry.
Dual-Side Clamping
Squeezes small carton blanks simultaneously from both ends. The through-rod design ensures both clamping faces meet with identical 70 kgf maximum pressure.
Is the Airtac SED Double Rod Cylinder SED32X155S the Right Cylinder?
At 0.5 MPa, this 32 mm bore generates 345 N of equal bidirectional force. If your mechanism requires less thrust, stepping down is not possible as 32 mm is the smallest SED bore. If you need more power, the next size up is the 40 mm bore, which provides 528 N both ways at 0.5 MPa. Choose this double-rod SED over a single-rod SE when the application demands anti-rotation guidance, dual-side loading, or rear-rod tooling. Remember that a plain SED will drift on air loss; for fail-safe position holding, specify a BSED double-rod lock cylinder. For this 155 mm stroke, external load guides are recommended to prevent side-load damage to the rod seals. To replace an existing ISO 15552 unit, match the 32 mm bore, 155 mm stroke, PT1/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Quick checklist
- ✓ Equal force/speed both directions needed?
- ✓ Back-rod space for tooling or a flag
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Support both rod ends; avoid side load.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SED Double Rod Cylinder SED32X155S FAQ
Because the double-rod design equalizes the piston area, force is identical in both directions: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and a maximum of 70 kgf at 1.0 MPa.
A rod exits both ends, providing superior anti-rotation guidance for external loads. The rear rod can also mount a sensor flag or secondary tool, and the cylinder drops into any standard ISO 15552 profile mounting footprint.
