Airtac SED Double Rod Cylinder SED40X95
The AirTAC Airtac SED Double Rod Cylinder SED40X95 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø16mm piston rod exits BOTH ends of the Ø40mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 95mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X95
The AirTAC SED40X95 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40 mm bore and 95 mm stroke. Because a 16 mm rod exits both end covers, the effective piston area is identical on extend and retract. This yields exactly 528 N of force each way at 0.5 MPa, providing perfectly balanced motion for demanding tasks.
The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in seamlessly for any ISO 15552 dimensional replacement. This specific SKU lacks the -S magnet option, meaning it operates without position sensing. You can thread rear-rod tooling directly onto the M12x1.25 end to drive a secondary mechanism.

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 (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 SED40X95 Is Used
PCB Depaneling Saw
Drives a dual-sided blade carrier with 528 N of equal force, utilizing the twin 16 mm rods to prevent blade deflection during precise V-groove cutting.
Pneumatic Gripper Sync
Uses the rear M12x1.25 rod end to mirror a secondary jaw movement, ensuring perfectly synchronized part transfer without rotational play.
Web Guide Roller
Steers a textile alignment roller with balanced 739 N thrust at 0.7 MPa, leveraging the through-rod design for stable, equal-bidirectional tensioning.
Is the Airtac SED Double Rod Cylinder SED40X95 the Right Cylinder?
Select this 40 mm bore if your application requires balanced 528 N force at 0.5 MPa in both directions. If you need less power, step down to the 32 mm bore providing 345 N both ways. If your load demands more thrust, step up to the 50 mm bore delivering 825 N. Choose this double-rod configuration over a single-rod SE when you need superior anti-rotation guidance or wish to mount a cam on the rear rod. Note that air pressure alone does not hold position on power loss; for fail-safe holding, use a BSED rod lock or external check valve.
When replacing an ISO 15552 cylinder, match the 95 mm stroke, PT1/4 port, and mounting style. Supported mounts include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The field-adjustable air cushion at both ends decelerates the load near stroke end, but it is not a braking device.
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 SED40X95 FAQ
The SED40X95 delivers equal force in both directions because of the double-rod design. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and reaches a maximum of 108 kgf at 1.0 MPa.
A double-rod cylinder provides equal extend and retract forces, better load guidance against rotation, and a rear rod end for mounting secondary cams or tooling. It is dimensionally interchangeable per ISO 15552 but omits FB, CA, CB, and CR mounting options.
