Airtac SED Double Rod Cylinder SED100X220
The AirTAC Airtac SED Double Rod Cylinder SED100X220 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø100mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 220mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X220
The AirTAC SED100X220 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100 mm bore and 220 mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force in both directions at 3681 N (0.5 MPa) and 5153 N (0.7 MPa). The extruded aluminum barrel contains no external tie rods, ensuring a clean, dimensionally interchangeable ISO 15552 footprint.
This unit uses a PT1/2 port and a 25 mm rod with an M20x1.5 thread. It includes field-adjustable air cushioning at both ends (36 mm cushion length) to decelerate loads near stroke extremes. This specific SKU lacks the -S magnet option, so it does not support CMSE or DMSE position sensing without modification.
Airtac SED Double Rod Cylinder SED100X220 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 220 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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 |
| Cushion | Adjustable, 36 mm |
| Max stroke | Up to 1500 mm |
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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 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 SED100X220 Is Used
CNC Fixture Clamping
Provides 5153 N of equal bidirectional force at 0.7 MPa to clamp heavy cast iron engine blocks during CNC machining, using the rear rod to simultaneously actuate a secondary chip-deflector gate.
Heavy-Duty Press Leveling
Utilizes the twin-rod anti-rotation property to keep a 100 mm bore press platen perfectly aligned while stamping automotive sheet metal, absorbing impact with 36 mm adjustable air cushions.
Pallet Transfer Diverter
Drives a dual-action diverter arm on a heavy-load pallet conveyor, extending and retracting with identical 3681 N at 0.5 MPa to push 500 kg skids smoothly without twisting.
Is the Airtac SED Double Rod Cylinder SED100X220 the Right Cylinder?
Selecting this 100 mm bore provides 5153 N of bidirectional force at 0.7 MPa. If your application requires less force, stepping down to the 80 mm bore yields 2268 N at 0.5 MPa. For heavier demands, the 125 mm bore provides 5734 N at 0.5 MPa. The twin-rod design is crucial when you need to drive mechanisms from both ends, mount a rear cam, or prevent load rotation without external guides. At 220 mm stroke, the 25 mm rod is robust, but external linear guides are recommended to manage side loads and prevent binding.
This SED cylinder is a drop-in replacement for any ISO 15552 double-rod unit matching its 100 mm bore, 220 mm stroke, and PT1/2 port. Note that a plain SED does not hold position on air loss; the piston drifts. For fail-safe holding, consider an AirTAC BSED double-rod rod lock or an external pilot-operated check valve. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and 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 SED100X220 FAQ
Because the double-rod design creates equal piston areas on both sides, force is identical in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
The twin-rod configuration allows you to mount tooling, cams, or sensors on the rear rod while preventing load rotation. It also ensures identical extend and retract speeds and forces, which is critical for synchronized dual-action machinery.
