Airtac SED Double Rod Cylinder SED100X35
The AirTAC Airtac SED Double Rod Cylinder SED100X35 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 35mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X35
The AirTAC SED100X35 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 35mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract. This means you get exactly 3681 N of output force at 0.5 MPa in both directions, preventing the speed and force mismatch common to single-rod units.
This extruded aluminum profile cylinder omits external tie rods and provides field-adjustable air cushioning at both ends to decelerate loads smoothly. The rear rod extension allows you to mount a cam or secondary mechanism, and it enhances load guidance against rotation. This specific SKU lacks a magnet, so position sensing is not available without modification.
Airtac SED Double Rod Cylinder SED100X35 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 35 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 SED100X35 Is Used
Injection Mold Clamping
Drives an injection mold clamping fixture requiring 3681 N of equal both-way force to securely seat and release heavy plastic molds without rotational drift.
Panel Bending Press
Operates a sheet metal bending press where the twin-rod design ensures the 100mm bore platen stays perfectly parallel during 5153 N peak forming strokes.
Indexing Drive Cam
Uses the rear rod end to mechanically trigger an indexing valve cam, leveraging the 3681 N force to shift heavy conveyor pallets at 35mm stroke.
Is the Airtac SED Double Rod Cylinder SED100X35 the Right Cylinder?
Choose this 100mm bore if your mechanism needs balanced 3681 N force at 0.5 MPa both ways. If you need less force, the 80mm bore provides 2268 N both ways; if you need more, the 125mm bore yields 5734 N. The twin-rod design is superior to a single-rod SE cylinder when driving loads that require high anti-rotation stability or dual-side tooling. To replace an ISO 15552 unit, match the 100mm bore, 35mm stroke, PT1/2 port, and your mounting choice from Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that a plain SED does not hold position on air loss; for fail-safe holding, use a BSED double-rod rod lock cylinder or an external lock.
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 SED100X35 FAQ
Because it is a double-rod cylinder, the 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.
Yes. The SED100X35 is dimensionally interchangeable per ISO 15552. Just match the 100mm bore, 35mm stroke, PT1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
