About the Airtac SCJ32 Standard Cylinder SCJ32X500-40
The SCJ32X500-40 is a double-acting, single-rod pneumatic cylinder from the AirTAC SCJ adjustable-stroke family. With a 32 mm bore and a nominal stroke of 500 mm, it delivers a push force of 402 N at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa. The rear-cap adjusting screw provides a 40 mm range to fine-tune the stroke end position, making it ideal for commissioning and process adjustments without changing the cylinder.
This model features a 12 mm diameter piston rod with an M10x1.25 thread and PT1/8 ports. The body length A(SCJ) is 182 mm, and it includes a 21 mm adjustable air cushion for smooth deceleration. The SCJ32X500-40 is a tie-rod cylinder, not an ISO 15552 type, and is designed for direct replacement of another AirTAC SCJ of the same configuration.
Airtac SCJ32 Standard Cylinder SCJ32X500-40 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X500-40 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 40 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 SCJ32X500-40 Is Used
End-Stop Calibration
The 40 mm adjustment screw allows operators to precisely dial in the retract or extend end position during machine commissioning, compensating for small differences in tooling or fixture placement.
Wear Compensation
In high-cycle pick-and-place systems, the adjustable stroke can be periodically tweaked to take up mechanical wear in linkages or contact surfaces, maintaining consistent part placement without immediate cylinder replacement.
Format Changeover
For light packaging or assembly machines that handle different product sizes, the stroke can be quickly adjusted on the line to match a new format, reducing changeover time compared to swapping fixed-stroke cylinders.
Is the Airtac SCJ32 Standard Cylinder SCJ32X500-40 the Right Cylinder?
Choose the SCJ32X500-40 when you need a compact, field-adjustable stroke end within a 40 mm window. If your force requirement increases, the next step up is the SCJ40 bore, which provides 628 N of push force at 0.5 MPa. For applications where the stroke never needs adjustment, the fixed-stroke SC32 cylinder is a simpler, cost-effective alternative. At a 500 mm stroke, ensure the rod is adequately supported against side loads; if the load is not guided, consider adding an external guide rail or switching to a guided cylinder to prevent rod bending and premature seal wear. A direct replacement must match the 32 mm bore, 500 mm nominal stroke, 40 mm adjust range, PT1/8 ports, and basic mounting.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-40)
- ✓ 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 SCJ32X500-40 FAQ
The push force is 402 N at 0.5 MPa, 563 N at 0.7 MPa, and 724 N at the maximum operating pressure of 0.9 MPa. The pull force is lower due to the 12 mm rod area, delivering 345 N at 0.5 MPa. The theoretical maximum force at 1.0 MPa is 82 kgf.
You can, provided the mounting and porting are compatible. The SCJ32X500-40 has a slightly longer body (A=182 mm) to house the adjusting screw. You must also ensure the 40 mm adjustment range does not interfere with your machine's cycle, as the screw sets the stroke end and does not lock the piston in place when air pressure is lost.
