Airtac SCD Standard Cylinder SCD80X60
The AirTAC Airtac SCD Standard Cylinder SCD80X60 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø80mm bore, 60mm stroke, PT3/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD80X60
The SCD80X60 delivers a balanced 2268 N of force in both directions at 0.5 MPa, thanks to its double-rod design where the 25 mm rod passes through both end caps. This symmetry eliminates force differentials, making it ideal for short-stroke applications like clamping fixtures or precision alignment tasks where consistent motion in both directions is critical.
With a body length A of 257 mm, this 80 mm bore cylinder features a 28 mm adjustable air cushion on each end to decelerate the piston smoothly. The PT3/8 ports and M20x1.5 rod threads provide robust connections, while the through-rod offers inherent anti-rotation characteristics for better guidance than a single-rod cylinder in light-duty tooling setups.
Airtac SCD Standard Cylinder SCD80X60 Technical Specifications

|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø80 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 60 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| 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 (Ø80mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 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 SCD80X60 Is Used
Two-Sided Clamping
The equal force output in both directions makes this cylinder perfect for synchronized clamping fixtures where a workpiece is engaged from two opposing sides simultaneously.
Rear-Mounted Sensing
The protruding rear rod provides a convenient mounting point for a sensor flag or cam, enabling end-of-stroke detection without interfering with the primary tooling on the front rod.
Non-Rotating Alignment
The dual-rod support offers better resistance to rod rotation than a single-rod cylinder, useful for maintaining the orientation of a small alignment tool or probe during short, linear moves.
Is the Airtac SCD Standard Cylinder SCD80X60 the Right Cylinder?
This 80 mm bore model provides 2268 N at 0.5 MPa. If your application needs less force in a smaller envelope, the 63 mm bore SCD63 offers 1402 N. For higher thrust, the 100 mm bore SCD100 steps up to 3681 N. The double-rod design is the right pick when you need to mount tooling or a sensor flag on the rear rod, or require equal speed and force for a two-sided operation.
For a direct replacement, match the 80 mm bore, 60 mm stroke, PT3/8 port thread, and any mounting accessory from the SCD subset (Basic, FA, LB, or TC). If you need magnetic piston sensing, specify the -S suffix. Note that for strokes significantly longer than this 60 mm unit, a through-rod provides better support than a single rod, but substantial side loads still demand an externally guided cylinder.
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 SCD80X60 FAQ
The push and pull forces are identical because the piston rod occupies area on both sides. At 0.5 MPa, the force is 2268 N; at 0.7 MPa, it's 3175 N; and at the maximum operating pressure of 0.9 MPa, it reaches 4082 N.
Choose the SCD80 when you need equal force and speed in both directions, a rear rod extension for mounting tooling or sensors, or the improved guidance and anti-rotation that a through-rod provides. A single-rod SC80 is a better choice if you only need force in one direction and want a more compact, lower-cost cylinder.
