Airtac SED Double Rod Cylinder SED63X135
The AirTAC SED Double Rod Cylinder SED63X135 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø63mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 135mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X135
The AirTAC SED63X135 is a double-acting, double-rod profile cylinder conforming to ISO 15552 dimensional standards. Because a 20mm rod occupies both sides of the 63mm piston, the annular area is identical on extend and retract, yielding equal force both ways: about 1402 N at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile.
This unit lacks a standard magnet (-S), so it cannot host CMSE or DMSE position sensors directly on the barrel. However, the rear rod protrusion is highly useful for mounting a cam or external limit flag to trigger remote switches. Field-adjustable air cushions at both ends decelerate the load near the 135mm stroke limits.
Airtac SED Double Rod Cylinder SED63X135 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 135 mm |
| Configuration | Double rod, double acting |
| Port size | PT3/8 |
| Rod thread | M16×1.5 |
| 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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 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 SED63X135 Is Used
Web Guiding Mechanism
Provides 1402 N of equal bidirectional force to steer a paper web edge, using the rear rod to mount a cam for a dancer roller feedback arm.
Shuttle Transfer Unit
Transfers automotive stampings between press stations, leveraging the twin 20mm rods for anti-rotation guidance during the 135mm traverse.
PCB Stacker Alignment
Drives a centering gate for electronics assembly, applying the same 1402 N clamping pressure on both the extend and retract strokes.
Is the Airtac SED Double Rod Cylinder SED63X135 the Right Cylinder?
Choose this 63mm bore when you need 1402 N of bidirectional force at 0.5 MPa. If your load is lighter, step down to the 50mm bore providing 825 N both ways; if heavier, step up to the 80mm bore yielding 2268 N both ways. Select the SED over a single-rod SE when your mechanism requires dual-side guidance to prevent rotation, or when the rear rod must drive a secondary mechanism.
For ISO 15552 replacements, match the 135mm stroke, PT3/8 port, and M16x1.5 rod thread. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB/CA/CB/CR). Note that a plain SED drifts on air loss; use a BSED rod lock for fail-safe holding.
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 SED63X135 FAQ
Because the double-rod design subtracts rod area from both piston sides, force is equal in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
Yes. It matches ISO 15552 mounting-interface dimensions. Ensure your setup accommodates the longer overall length for rear-rod clearance and uses the PT3/8 port and M16x1.5 rod thread.
