About the Airtac SCJ40 Standard Cylinder SCJ40X130-100
The SCJ40X130-100 is a double-acting, single-rod pneumatic cylinder with a 40 mm bore and a 130 mm nominal stroke, equipped with a rear adjusting screw that provides a 100 mm field-adjustable range to fine-tune the stroke end position. Delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa, this tie-rod cylinder uses a 16 mm diameter rod and PT1/4 ports, making it a versatile actuator for applications where the stroke length must be dialed in during commissioning or changeover without swapping the cylinder.
The body length A for this SCJ series is 185 mm, and the cylinder includes an adjustable air cushion for smooth deceleration. The 100 mm adjustment range is particularly suited for processes that require significant end-position variability, such as accommodating different product sizes or taking up mechanical wear over time. This model is configured with a basic mount, TPU seals for standard -20 to +70 C operation, and PT threads.
Airtac SCJ40 Standard Cylinder SCJ40X130-100 Technical Specifications
| Model | Airtac SCJ40 Standard Cylinder SCJ40X130-100 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø40 mm |
| Nominal stroke | 130 mm |
| Stroke adjustment | Up to 100 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 SCJ40X130-100 Is Used
Commissioning & Setup Trials
The 100 mm adjustment range allows engineers to precisely dial in the optimal stroke end position on a new machine during initial setup and testing, eliminating the need to stock multiple fixed-stroke cylinders for trial runs.
Wear Compensation in Clamping
In high-cycle clamping fixtures, the adjustable stroke can be periodically extended to compensate for wear on clamp pads or workpieces, maintaining consistent clamping force without immediate part replacement.
Multi-Format Stopper Gates
Ideal for conveyor lines handling different box or pallet sizes, where the cylinder's stroke end can be quickly adjusted via the rear screw to act as a positive stop for varying product widths, simplifying format changeovers.
Is the Airtac SCJ40 Standard Cylinder SCJ40X130-100 the Right Cylinder?
For applications requiring a field-adjustable stroke end, this SCJ40 model is a direct fit. If your force requirements increase, stepping up to an SCJ50 bore provides 982 N of push force at 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC series offers a simpler, more compact alternative. A direct replacement must match the 40 mm bore, 130 mm nominal stroke, 100 mm adjustment range, PT1/4 ports, and basic mounting configuration. If you need a longer stroke, the SCJ40 can be ordered with a nominal stroke up to 1200 mm.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ40X130-100 FAQ
At an operating pressure of 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. The push force is higher because the single rod reduces the effective piston area on the return stroke. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 128 kgf.
The rear cap has an integrated adjusting screw that acts as an internal, variable end-stop for the piston. By turning this screw, you can shorten the stroke end position by up to 100 mm from the nominal 130 mm maximum. This adjusts the physical stopping point of the piston, not the air pressure or speed.
