Airtac SCD Standard Cylinder SCD63X60S
The AirTAC Airtac SCD Standard Cylinder SCD63X60S 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, 60mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD63X60S
The SCD63X60S is a double-acting, double-rod pneumatic cylinder where the piston rod extends from both ends, giving you identical push and pull force of 1402 N at 0.5 MPa. With a 20 mm diameter rod on each side and a 60 mm stroke, it is built for compact, two-sided tasks where you need to mount tooling or a sensor flag on the rear rod.
This model includes a built-in magnet (the -S suffix), so you can mount CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the tie-rod barrel for non-contact position sensing. The adjustable air cushion at each end (28 mm long) decelerates the piston smoothly, and the PT1/4 port threads keep it compatible with standard pneumatic fittings.
Airtac SCD Standard Cylinder SCD63X60S Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD63X60S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø63 mm |
| Rod diameter | Ø20 mm (both ends) |
| Stroke | 60 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 SCD63X60S Is Used
Two-Sided Actuation
The through-rod design lets you mount identical tooling on both ends, perfect for symmetrical clamping or pressing operations where you need equal force and speed from each side.
Rear-Mounted Stroke Sensing
With the built-in magnet, you can clamp a CMSG or DMSG sensor onto the barrel to detect piston position from the rear, keeping the front rod area clear for the main tooling.
Anti-Rotation Pusher
The dual-rod support provides better resistance to rod rotation than a single-rod cylinder, making it a solid choice for simple push-and-eject stations where you want to keep the tooling aligned without adding an external guide.
Is the Airtac SCD Standard Cylinder SCD63X60S the Right Cylinder?
Choose the 63 mm bore SCD when your application needs around 1400 N of force in both directions at typical shop air pressure. If you can work with less force, stepping down to the 50 mm bore SCD saves space and air (825 N at 0.5 MPa); for heavier loads, the 80 mm bore delivers 2268 N. This double-rod design is the right pick when you need to attach tooling, a stopper, or a position flag to the rear rod, but if your load creates significant side force, a guided cylinder is a safer choice than relying solely on the dual-rod bearings. For a direct replacement, match the 63 mm bore, 60 mm stroke, PT port thread, basic mounting, and the -S magnet option.
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 SCD63X60S FAQ
Because the SCD is a double-rod cylinder, the effective piston area is the same on both sides. The push and pull force are equal: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at the maximum operating pressure of 0.9 MPa.
Pick the SCD when you need the piston rod to do work on both ends of the cylinder. The rear rod can carry a second tool, a mechanical stop, or a sensor flag. It also gives you identical force and speed in both directions and better guidance for the rod assembly compared to a single-rod design.
