About the Airtac SCJ40 Standard Cylinder SCJ40X200-10S
The SCJ40X200-10S is a double-acting, single-rod pneumatic cylinder that puts fine-tuning at your fingertips. With a 40mm bore delivering 628 N of push force at 0.5 MPa (up to 1130 N at 0.9 MPa), it handles moderate clamping and positioning tasks. The rear adjusting screw offers a 10mm stroke-end reduction range, letting you dial in the exact stop position without swapping the cylinder or adding external hard stops.
This model includes a built-in magnet (-S), so you can directly mount CMSG/DMSG/EMSG reed or solid-state sensors on the tie-rod barrel for end-of-stroke detection. It uses a 16mm piston rod, PT1/4 ports, and an M12x1.25 rod thread. The 21mm air cushion at each end decelerates the piston smoothly, and the SCJ body length A is 185mm, making it a compact adjustable solution for machines that need frequent format changes.
Airtac SCJ40 Standard Cylinder SCJ40X200-10S Technical Specifications
| Model | Airtac SCJ40 Standard Cylinder SCJ40X200-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø40 mm |
| Nominal stroke | 200 mm |
| Stroke adjustment | Up to 10 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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 SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCJ40 Standard Cylinder SCJ40X200-10S Is Used
Commissioning & Setup
Use the 10mm rear adjustment screw to precisely dial in the push stroke end-stop during machine setup, eliminating the need to fabricate shims or reposition external stops.
Packaging Format Changeover
Quickly adjust the stroke length for different box or product sizes on a packaging line. The -S magnet allows sensors to confirm the new position is reached every cycle.
Clamping with Wear Compensation
In a clamping fixture, the adjustable stroke lets you take up slack as gripper pads wear down over time, maintaining consistent clamping force without reprogramming the machine.
Is the Airtac SCJ40 Standard Cylinder SCJ40X200-10S the Right Cylinder?
Choose the SCJ40 bore when your application needs roughly 628 N of push force at standard plant air. If you need more force, step up to the SCJ50 series, which provides 982 N of push at the same 0.5 MPa pressure. For lighter, more compact needs, the SCJ32 delivers 402 N. This adjustable-stroke model is ideal when you need to fine-tune the stroke end during commissioning or changeovers; if your stroke is absolutely fixed and never needs adjustment, a standard SC40 fixed-stroke cylinder is a simpler, more economical alternative. For a direct replacement, match the 40mm bore, 200mm nominal stroke, 10mm adjust range, PT port thread, and the built-in magnet (-S). At this 200mm stroke, ensure the rod is guided if significant side loads are present to prevent bending.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ Required force at your working pressure
- ✓ 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 Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ40 Standard Cylinder SCJ40X200-10S FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. The force increases with pressure, reaching 1130 N push at the maximum operating pressure of 0.9 MPa. Because it is a single-rod cylinder, the push force is greater than the pull force due to the rod area.
Yes, this is a genuine AirTAC SCJ40X200-10S. For a direct functional replacement, ensure your current cylinder has a 40mm bore, a 200mm nominal stroke, a 10mm adjustable range, PT ports, and a built-in magnet for sensors. The mounting style must also match your existing setup.
