Airtac SCD Standard Cylinder SCD50X60
The AirTAC Airtac SCD Standard Cylinder SCD50X60 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. Ø50mm bore, 60mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD50X60
The SCD50X60 is a double-acting pneumatic cylinder engineered with a through-rod design, providing identical 825 N output force in both directions at 0.5 MPa. Its 20 mm diameter rod extends from both end caps, making it ideal for tasks where a rear rod connection point is needed for mounting sensors, cams, or secondary tooling without asymmetrical force profiles.
With a 60 mm stroke and a body length A(SCD) of 207 mm, this model fits compact dual-action setups. The adjustable air cushion at each end decelerates the piston smoothly over 21 mm, and the PT1/4 port supplies the balanced thrust. At the maximum operating pressure of 0.9 MPa, the force rises to 1484 N each way.

| 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, 21 mm |
| Max stroke | Up to 1200 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 (Ø50mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 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 SCD50X60 Is Used
Bidirectional Clamping
The equal 825 N force in both directions makes the SCD50X60 perfect for clamping fixtures where the jaw must open and close with identical pressure, preventing part distortion.
Rear Stroke Sensing
The exposed rear rod provides a clean mounting point for a sensor flag or limit switch cam, enabling end-of-stroke detection without attaching brackets to the moving load.
Two-Sided Transfer Shuttle
Use the front rod to push a workpiece and the rear rod to simultaneously return a stop gate, creating a synchronized material handling sequence from one valve signal.
Is the Airtac SCD Standard Cylinder SCD50X60 the Right Cylinder?
Choose the SCD50X60 when your mechanism requires equal push and pull force from a single actuator. If you need more thrust, stepping up to the 63 mm bore SCD63 series provides 1402 N at 0.5 MPa. For applications that only need force from one side, a single-rod SC50 cylinder is a simpler, more compact alternative. This double-rod model is not a guided cylinder; for significant side loads, add an external guide rail. A drop-in replacement must match the 50 mm bore, 60 mm stroke, PT port thread, and basic mounting style.
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 SCD50X60 FAQ
Because the piston rod passes through both ends, the effective pressure area is identical for push and pull. The force is 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at the maximum operating pressure of 0.9 MPa.
Select the SCD when you need perfectly balanced force and speed in both directions, or when you need to attach tooling or sensors to the rod on the cap-end side. The dual-rod support also provides better resistance to rod bending than a single-rod cylinder of the same bore.
