About the Airtac SCJ32 Standard Cylinder SCJ32X500-10S
The SCJ32X500-10S is a double-acting, single-rod tie-rod cylinder that puts stroke-end fine-tuning directly on the machine. Its rear adjusting screw provides up to 10 mm of retraction from the 500 mm nominal stroke, letting commissioning engineers dial in the exact end position without shimming or swapping the cylinder body.
With a 12 mm diameter piston rod and PT1/8 ports, this 32 mm bore unit delivers 402 N of push force at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa. The built-in magnet (suffix -S) allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for clean, bolt-on position sensing.
Airtac SCJ32 Standard Cylinder SCJ32X500-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X500-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 10 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 SCJ32X500-10S Is Used
Commissioning & Setup
Technicians can fine-tune the 500 mm stroke end by up to 10 mm on the fly, quickly compensating for fixture tolerances during initial machine bring-up without removing the cylinder.
Wear Take-Up in Material Handling
On a long-stroke pusher or diverter, the adjusting screw compensates for gradual wear on contact pads or grippers, maintaining consistent product placement over thousands of cycles.
End-Stop Calibration
In a gauging or clamping station, the 10 mm adjustment range allows operators to dial in a precise hard stop, ensuring repeatable part positioning without external mechanical stops.
Is the Airtac SCJ32 Standard Cylinder SCJ32X500-10S the Right Cylinder?
Choose the SCJ32X500-10S when a 32 mm bore provides sufficient force and the application benefits from a field-adjustable stroke end. If the force requirement grows, stepping up to the 40 mm bore yields 628 N of push at 0.5 MPa. For applications where the stroke is permanently fixed and never needs adjustment, the standard SC32X500 offers a simpler, cost-effective alternative. This model is a direct replacement for an existing AirTAC SCJ32X500-10S with PT threads, basic mounting, and a magnet. At 500 mm of stroke, ensure the rod is guided externally if significant side loads are present to prevent rod bending and premature seal wear.
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 SCJ32 Standard Cylinder SCJ32X500-10S FAQ
A rear-cap adjusting screw limits the piston's outward travel, allowing you to shorten the 500 mm nominal stroke by up to 10 mm. This sets a precise end position but does not change the cylinder's bore, force output, or speed.
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N. The pull force is lower due to the area of the 12 mm piston rod.
