About the Airtac SCJ40 Standard Cylinder SCJ40X160-10S
The SCJ40X160-10S is a double-acting, single-rod pneumatic cylinder from AirTAC with a field-adjustable stroke end. A rear-cap screw provides up to 10 mm of fine adjustment, letting you dial in the exact stroke position during commissioning or format changes. The 40 mm bore delivers 628 N of push force at 0.5 MPa and 1130 N at 0.9 MPa, making it a solid mid-range actuator.
This model includes a built-in magnet (-S), so CMSG, DMSG, or EMSG solid-state sensors can be clamped directly onto the tie-rod barrel for reliable end-of-stroke detection. The 16 mm piston rod and PT1/4 ports are standard for the 40 mm bore, and the adjustable air cushion decelerates the load smoothly at both ends. The body length A(SCJ) is 185 mm plus stroke, slightly longer than a fixed-stroke SC to house the adjusting mechanism.
Airtac SCJ40 Standard Cylinder SCJ40X160-10S Technical Specifications
| Model | Airtac SCJ40 Standard Cylinder SCJ40X160-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø40 mm |
| Nominal stroke | 160 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 SCJ40X160-10S Is Used
Commissioning Fine-Tuning
The 10 mm rear adjustment screw lets technicians dial in the precise end-stop position during machine setup without swapping cylinders or machining external hard stops.
Format Changeover
On packaging lines, adjust the stroke end in seconds to accommodate different box or product sizes, reducing downtime between production runs.
Sensor-Ready Positioning
The built-in magnet works with CMSG/DMSG sensors to provide clean, repeatable end-of-stroke signals, even after the stroke length is adjusted in the field.
Is the Airtac SCJ40 Standard Cylinder SCJ40X160-10S the Right Cylinder?
Choose the SCJ40X160-10S when you need to fine-tune the stroke end on a 40 mm bore platform. If 628 N of push force at 0.5 MPa is marginal, stepping up to a 50 mm bore provides 982 N; if space is tight, the 32 mm bore offers 402 N. The adjustable stroke is ideal for commissioning trials, but once a stroke is permanently fixed, a standard SC cylinder is a simpler, lower-cost alternative.
For replacement, match the bore (40 mm), nominal stroke (160 mm), and the -10 adjustment range. This unit uses PT threads and a basic mount; the built-in magnet must also be present on the replacement. At 160 mm of stroke, side-loading is generally manageable, but for off-axis loads, consider an external guide rail or a guided cylinder to protect the rod bearing.
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 SCJ40X160-10S FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 128 kgf. Because it is a single-rod cylinder, the push force is always greater than the pull force due to the rod area.
Yes, provided the bore (40 mm), nominal stroke (160 mm), port thread (PT), and mounting style match. The SCJ body is slightly longer (A=185 mm + stroke) to house the adjusting screw. Ensure the -S magnet option is selected if your application uses barrel-mounted sensors.
