Airtac SCD Standard Cylinder SCD160X500
The AirTAC Airtac SCD Standard Cylinder SCD160X500 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø40mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø160mm bore, 500mm stroke, PT3/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD160X500
The SCD160X500 is a large-bore double-rod pneumatic cylinder that outputs an identical 9425 N in both extend and retract directions at 0.5 MPa, rising to 16964 N at the 0.9 MPa maximum operating pressure. This symmetry comes from the Ø40 mm piston rod passing through both end caps, subtracting the same area on each side and providing a rear rod end for mounting cams, stopper bolts, or external sensor flags.
With a 500 mm stroke and a 352 mm body length A(SCD), this tie-rod cylinder suits heavy transfer shuttles and dual-sided tooling where balanced thrust prevents uneven wear. The adjustable air cushion (29 mm length) decelerates the high-inertia piston smoothly, while the PT3/4 ports supply ample flow for the 30-500 mm/s speed range expected of an ISO 6430 class cylinder.
Airtac SCD Standard Cylinder SCD160X500 Technical Specifications

| Series | SCD double-rod tie-rod cylinder (ISO 6430 class) |
| Bore size | Ø160 mm |
| Rod diameter | Ø40 mm (both ends) |
| Stroke | 500 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT3/4 |
| Rod thread | M36×2 |
| 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 – 500 mm/s |
| Cushion | Adjustable, 29 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 (Ø160mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | 13195 N |
| Max (@1.0 MPa) | 1922 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 SCD160X500 Is Used
Heavy Pallet Transfer
The equal 9425 N push-pull force moves loaded pallets smoothly in both directions on a shuttle table, with the rear rod providing a mounting point for a shock absorber.
Dual-Sided Welding Fixture
Operates clamping arms on both ends of the cylinder simultaneously, using the through-rod to synchronize tooling without complex linkages.
Large Part Ejector
Delivers a powerful, balanced thrust to strip heavy moulded parts from a die, with the rear rod extension tripping a limit switch for cycle confirmation.
Is the Airtac SCD Standard Cylinder SCD160X500 the Right Cylinder?
Choose the SCD160 when your application demands symmetric force around 9425 N at 0.5 MPa. If you can accept a lower balanced output, the SCD125 provides 5734 N in a lighter package; for heavier loads, the SCD200 steps up to 15080 N. A double-rod cylinder is the right call when you need tooling on both ends or equal speed control, but if you only require force from one side, the single-rod SC160 is a simpler, more compact alternative.
At a 500 mm stroke, the long unsupported rod on each end can act as a lever under side load. If your tooling imposes any lateral force, pair this cylinder with an external guide rail or switch to a dedicated guided cylinder to protect the rod bearings and ensure long service life. For drop-in replacement, match the 160 mm bore, 500 mm stroke, PT port thread, and basic mounting style of an existing AirTAC SCD160.
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 SCD160X500 FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 9425 N, at 0.7 MPa it produces 13194 N, and at the maximum operating pressure of 0.9 MPa it reaches 16964 N.
Choose the SCD160 when you need perfectly equal force and speed in both directions, or when you require a second rod end to mount tooling, a sensor target, or a mechanical stop. The through-rod design also provides better guidance than a single-rod cylinder, though it is not a substitute for an external guide under high side loads.
