Airtac SCD Standard Cylinder SCD63X175S
The AirTAC Airtac SCD Standard Cylinder SCD63X175S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø20mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø63mm bore, 175mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD63X175S
The SCD63X175S is a double-acting, double-rod pneumatic cylinder delivering identical push and pull force of 1402 N at 0.5 MPa (2523 N at 0.9 MPa). Its 20 mm diameter rod extends from both ends, providing symmetric thrust and a rear rod end that can carry a sensor flag, stopper, or secondary tooling. The built-in magnet (denoted by the -S suffix) allows CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing.
This 175 mm stroke model is within the standard stroke range for the 63 mm bore, which supports strokes up to 1500 mm. The body length A(SCD) is 210 mm, making the overall retracted length longer than an equivalent single-rod SC cylinder. Adjustable pneumatic cushioning at both ends, with a 28 mm cushion length, decelerates the piston smoothly, protecting the end caps during high-cycle operation.
Airtac SCD Standard Cylinder SCD63X175S Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD63X175S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø63 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 175 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/4 |
| 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 |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke | Up to 1500 mm |
Specifications follow the official AirTAC SCD (double-rod) datasheet. Because the rod runs through both caps, the effective area is (bore² − rod²) in both directions. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø63mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 kgf | |
Push and pull are EQUAL on a double-rod cylinder — both chambers lose the rod area, so effective area = (bore² − rod²) each way. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCD Standard Cylinder SCD63X175S Is Used
Two-Sided Actuation
The rear rod extends to operate a mirror mechanism or secondary clamp on the opposite side of the machine, synchronizing two actions with one cylinder.
Transfer Shuttle
Moves a part between two conveyor lanes. The equal push-pull force ensures consistent acceleration and deceleration in both travel directions.
Rear Stroke Sensing
The -S magnet allows a CMSG sensor to be mounted on the rear barrel to confirm full retraction via the rear rod's position, even when the front rod is obscured.
Is the Airtac SCD Standard Cylinder SCD63X175S the Right Cylinder?
This 63 mm bore SCD suits applications needing balanced two-way force around 1400 N at standard plant pressure. If your load requires less thrust, stepping down to the 50 mm bore (825 N at 0.5 MPa) saves air and space. For higher force, the 80 mm bore (2268 N at 0.5 MPa) is the next step up. Choose this double-rod model over a single-rod SC when you need equal speed and force in both directions, a rear rod for external actuation, or better resistance to rod rotation.
For a direct replacement, match the 63 mm bore, 175 mm stroke, PT port thread, basic mounting, and the -S magnet option. The SCD series uses a tie-rod construction, so it is not dimensionally interchangeable with ISO 15552 profiles. If you are pushing a heavy, off-centre load, a through-rod offers more guidance than a single rod but cannot substitute for an external guide rail or a dedicated guided cylinder under substantial side forces.
Double-rod checklist
- ✓ Need equal force / speed both directions?
- ✓ Rear rod for tooling, stopper or sensor flag?
- ✓ Better rod guidance / anti-rotation?
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Keep BOTH rod ends clear of side load and interference.
- check Adjust end cushion screws for smooth stops.
- check Use SCD mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCD Standard Cylinder SCD63X175S FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 1402 N, at 0.7 MPa it produces 1962 N, and at the maximum operating pressure of 0.9 MPa it delivers 2523 N in both directions.
Choose the SCD when you need perfectly equal force and speed in both directions, or when you need to mount tooling, a stop, or a sensor flag on the rear rod. The through-rod design also provides better guidance and inherent anti-rotation compared to a single-rod cylinder of the same bore.
