About the Airtac SCJ32 Standard Cylinder SCJ32X200-50
The SCJ32X200-50 is a double-acting, single-rod pneumatic cylinder with a built-in rear adjusting screw that provides up to 50 mm of field-adjustable stroke end reduction. This allows machine builders to fine-tune the piston stop position without swapping the cylinder, making it ideal for commissioning trials and format changeovers. With a 32 mm bore and 12 mm rod, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This adjustable-stroke cylinder uses PT1/8 ports and an M10x1.25 rod thread, with a 21 mm air cushion for smooth deceleration. The body length A is 182 mm, and the maximum standard stroke for this bore is 1000 mm. Its tie-rod construction ensures robust, repairable service in industrial automation tasks.
Airtac SCJ32 Standard Cylinder SCJ32X200-50 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X200-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 200 mm |
| Stroke adjustment | Up to 50 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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 1000 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCJ32 Standard Cylinder SCJ32X200-50 Is Used
Commissioning & Setup
The 50 mm adjustable stroke end allows technicians to dial in the exact stopping position during machine commissioning without changing hard stops or cylinder mounts, saving hours of setup time on packaging and assembly lines.
Product Format Changeover
Quickly adapt the cylinder's stroke for different product sizes on a conveyor diverter or sorting gate. The rear screw adjustment enables a single actuator to handle multiple formats, reducing changeover downtime.
Wear Compensation
In clamping or pressing fixtures, the adjustable stroke can be used to take up mechanical wear on tooling or contact surfaces over time, maintaining consistent clamping force without replacing the cylinder.
Is the Airtac SCJ32 Standard Cylinder SCJ32X200-50 the Right Cylinder?
Choose the SCJ32 when your application requires a compact cylinder with a push force around 400 N at 0.5 MPa and the flexibility to adjust the stroke end by up to 50 mm. If you need more force, the next step up is the SCJ40, which provides 628 N of push force at the same pressure. For applications where the stroke must remain absolutely fixed after installation, a standard SC fixed-stroke cylinder is a simpler, more cost-effective choice.
This model is a direct replacement for an existing AirTAC SCJ32X200-50 with basic mounting, PT ports, TPU seals, and no magnet. For strokes of 200 mm, ensure the rod is not subjected to high side loads; if lateral forces are present, consider adding an external linear guide or switching to a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-50)
- ✓ 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 SCJ32 Standard Cylinder SCJ32X200-50 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The push force is higher because the single-rod design means air pressure acts on the full bore area during extension, while the rod area is subtracted during retraction. The maximum push force at 0.9 MPa is 724 N.
It can physically fit, but it is not a direct functional replacement. The SCJ32X200-50 has a longer body to house the adjusting screw and allows you to shorten the stroke end by up to 50 mm. If you need a cylinder with an identical fixed 200 mm stroke, you should order the standard SC32X200 model instead.
