About the Airtac SCJ32 Standard Cylinder SCJ32X25-10
The SCJ32X25-10 is a compact adjustable-stroke cylinder that delivers 402 N of push force at 0.5 MPa, making it ideal for light clamping and positioning tasks. The rear adjusting screw provides up to 10 mm of stroke-end fine-tuning, allowing operators to dial in the exact stopping position without swapping the cylinder.
With a 12 mm piston rod and PT1/8 ports, this double-acting, single-rod unit shares the same force profile as the fixed-stroke SC series. Its tie-rod construction and 21 mm air cushion ensure reliable deceleration in a body length of just 182 mm, perfect for space-constrained automation.
Airtac SCJ32 Standard Cylinder SCJ32X25-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X25-10 |
|---|---|
| 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 SCJ32X25-10 Is Used
Commissioning Fine-Tuning
The 10 mm rear screw adjustment lets technicians precisely set the stroke end on new machinery, eliminating the need for custom spacers or hard stops during initial setup.
Small Part Positioning
Ideal for light-duty diverters or stops on conveyor lines, where the adjustable stroke compensates for varying product sizes without reprogramming the PLC.
Wear Take-Up
In cyclic pressing operations, the adjustable screw can be advanced slightly over time to compensate for tooling or pad wear, maintaining consistent contact force.
Is the Airtac SCJ32 Standard Cylinder SCJ32X25-10 the Right Cylinder?
Choose the SCJ32X25-10 when you need to fine-tune the stroke end during commissioning or format changes. If 402 N of push force is insufficient, stepping up to the 40 mm bore provides 628 N at the same pressure. For applications requiring a fixed, non-adjustable stroke, the standard SC32X25 is a direct alternative.
A genuine replacement must match the 32 mm bore, 25 mm nominal stroke, 10 mm adjust range, and PT port thread. This model uses a basic mount; if a pivoting motion is required, consider adding a TC centre trunnion with the F-SC32TC bracket.
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 SCJ32X25-10 FAQ
At 0.5 MPa, it produces 402 N pushing and 345 N pulling. The maximum push force at the 0.9 MPa operating limit is 724 N. The pull force is lower because the 12 mm rod reduces the effective piston area on the return stroke.
Yes, provided the 10 mm longer body length is acceptable. The SCJ32X25-10 has the same bore, port size, and mounting footprint, but adds the rear adjusting screw for field-adjustable stroke-end control.
