About the Airtac SCJ32 Standard Cylinder SCJ32X25-10S
The SCJ32X25-10S is a compact double-acting, single-rod cylinder that puts fine stroke control directly into your hands. Its rear adjusting screw provides up to 10 mm of end-position adjustment, letting you dial in the exact stopping point during commissioning or after wear without swapping the cylinder. The built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke sensing.
With a 12 mm piston rod and M10x1.25 rod thread, this 32 mm bore cylinder delivers 402 N of push force at 0.5 MPa. The body length is 182 mm plus stroke, and the adjustable air cushion decelerates the piston smoothly over the final 21 mm of travel. It uses PT1/8 ports and operates on filtered air from 0.15 to 1.0 MPa.
Airtac SCJ32 Standard Cylinder SCJ32X25-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X25-10S |
|---|---|
| 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 SCJ32X25-10S Is Used
Commissioning Fine-Tuning
Adjust the 10mm stroke end on the fly to perfectly align a pick-and-place gripper without re-machining stops or swapping cylinders.
Wear Take-Up on Stops
Compensate for pad or workpiece wear in a clamping station by tweaking the rear screw, maintaining consistent clamping force without downtime.
Small-Part Ejector
Use the sensor-ready magnet to confirm retraction after each cycle in a compact assembly fixture, ensuring no part is left behind.
Is the Airtac SCJ32 Standard Cylinder SCJ32X25-10S the Right Cylinder?
Choose the SCJ32X25-10S when you need a compact, sensor-ready actuator with field-adjustable stroke end. If your application demands more force, stepping up to the 40 mm bore provides 628 N of push at the same 0.5 MPa. For applications where the stroke is permanently fixed and never needs field tuning, the standard SC32X25-S offers a simpler, non-adjustable alternative.
As a direct replacement, match the 32 mm bore, 25 mm nominal stroke, 10 mm adjustment range, PT1/8 port thread, and the -S magnet option. This model uses the basic mounting style; if you later need a pivot mount, the TC centre trunnion with TCM1 bracket (F-SC32TC) can be added.
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 SCJ32X25-10S FAQ
At the standard 0.5 MPa operating pressure, it generates 402 N of push force and 345 N of pull force (the difference is due to the single 12 mm rod). At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 804 N.
Yes, the -S suffix means a magnet is built into the piston. You can mount any AirTAC CMSG, DMSG, or EMSG series sensor directly onto the cylinder's tie-rod barrel to detect piston position.
