About the Airtac SCJ32 Standard Cylinder SCJ32X25-10TC
The SCJ32X25-10TC is a double-acting, single-rod pneumatic cylinder that puts fine stroke-end adjustment directly on the machine. Its rear-cap screw provides a 10 mm adjustable range, letting you dial in the exact 25 mm nominal stroke end for commissioning or format changes without adding external hard stops. With a 12 mm diameter piston rod and M10x1.25 rod-end threads, it delivers 402 N of push force at 0.5 MPa.
This model is configured with a TC centre trunnion mount (supplied with the TCM1 bracket, order code F-SC32TC), making it ideal for applications where the cylinder body needs to pivot. The standard PT1/8 ports and TPU seals suit filtered-air systems from -20 to +70 °C. The body length A(SCJ) is 182 mm, and it includes an adjustable air cushion for smooth deceleration.
Airtac SCJ32 Standard Cylinder SCJ32X25-10TC Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X25-10TC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 25 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 SCJ32X25-10TC Is Used
Commissioning & Setup
The 10 mm adjustment screw lets technicians fine-tune the end position during initial machine setup, compensating for small assembly tolerances without remounting the cylinder.
Small-Part Diverter Gates
A pivoting diverter on a packaging line uses the TC trunnion mount. The adjustable stroke allows operators to perfectly align the gate with different lane widths as products change.
Wear Take-Up in Clamping
In a repetitive clamping fixture, the adjustable stroke end can be extended slightly over time to compensate for pad wear, maintaining consistent clamping force without replacing parts.
Is the Airtac SCJ32 Standard Cylinder SCJ32X25-10TC the Right Cylinder?
Choose the SCJ32 when your application needs up to 402 N of push force at 0.5 MPa. If your load requires more force, step up to the SCJ40, which provides 628 N of push at the same pressure. For applications that do not need field-adjustable stroke, the fixed-stroke SC32 is a simpler, more compact alternative. This cylinder is a direct replacement for another AirTAC SCJ32 with a 25 mm nominal stroke, 10 mm adjustment range, PT ports, and TC trunnion mount.
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 SCJ32X25-10TC FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum operating push force at 0.9 MPa is 724 N. Because it is a single-rod cylinder, the pull force is lower due to the area of the 12 mm rod.
A screw in the rear cap lets you shorten the stroke end by up to 10 mm from the 25 mm nominal maximum. It sets the physical stop position for the piston, allowing quick, toolless adjustment on the machine without changing the cylinder's mounting.
