Airtac SED Double Rod Cylinder SED80X105S
The AirTAC Airtac SED Double Rod Cylinder SED80X105S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø80mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 105mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X105S
The AirTAC SED80X105S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a Ø25 mm rod extends from both end covers, the effective piston area is identical on extend and retract. This yields exactly 2268 N of force both ways at 0.5 MPa, eliminating speed and force mismatches between strokes.
Equipped with the -S magnet option, this unit supports CMSE reed and DMSE electronic sensors for tracking position from either end. The extruded aluminum barrel contains no external tie rods, and field-adjustable air cushions at both ends decelerate the 105 mm stroke smoothly.

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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SED80X105S Is Used
Servo Press Peening
Drives a dual-sided peening head with 2268 N equal force, using the rear rod to mount a linear scale for closed-loop depth verification.
Glass Panel Lifters
Transfers heavy glass sheets by clamping from both ends simultaneously, leveraging the anti-rotation properties of the twin rods to prevent yaw.
Textile Calendering
Regulates roller pressure symmetrically, ensuring uniform fabric thickness by applying identical 3175 N clamping force during extend and retract.
Is the Airtac SED Double Rod Cylinder SED80X105S the Right Cylinder?
Select this 80 mm bore when you need 2268 N both ways at 0.5 MPa. If your load is lighter, the 63 mm bore offers 1402 N; if you need more thrust, the 100 mm bore provides 3681 N. The twin-rod design inherently resists torsional rotation, making it superior to a single-rod SE cylinder for driving loads that cannot twist.
This cylinder includes a -S magnet for DMSE/CMSE sensors and uses a PT3/8 port. Remember that a plain SED does not hold position on air loss—the piston drifts, and the adjustable cushion only decelerates near stroke end. For fail-safe holding, use an external rod lock or a BSED double-rod rod lock cylinder. Ensure interchangeability by matching the 80 mm bore, 105 mm stroke, and mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SED80X105S FAQ
The SED80X105S provides equal force in both directions because of the double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
A double-rod cylinder provides identical force and speed in both directions, which is critical for symmetric operations. The rear rod also allows you to mount a cam or sensor flag, and the twin rods guide the load against rotation better than a single rod.
