About the Airtac SCJ32 Standard Cylinder SCJ32X255-10
The SCJ32X255-10 is a double-acting, single-rod pneumatic cylinder from AirTAC, featuring a rear-cap adjusting screw that provides a 10 mm field-adjustable stroke range. This allows you to fine-tune the end position without swapping the cylinder, ideal for commissioning and format changeovers. With a 32 mm bore and a 12 mm rod, it delivers a push force of 402 N at 0.5 MPa, making it a compact yet capable actuator for light automation tasks.
The cylinder body has a length of 182 mm and uses PT1/8 ports with an M10x1.25 rod thread. Its air cushion is 21 mm long, providing smooth deceleration. This model is built on a durable tie-rod construction and operates on filtered air from 0.15 to 1.0 MPa. The standard stroke for this bore goes up to 1000 mm, so the 255 mm stroke here is well within standard limits, ensuring quick availability.
Airtac SCJ32 Standard Cylinder SCJ32X255-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X255-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 255 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 SCJ32X255-10 Is Used
End-Stop Fine-Tuning
The 10 mm adjusting screw lets operators dial in the precise stroke end for pick-and-place mechanisms, compensating for minor variations in workpiece position without reprogramming the controller.
Wear Compensation
In light-duty clamping fixtures, the adjustable stroke can be used to take up slack as gripper pads wear over time, maintaining consistent clamping force without mechanical shimming.
Commissioning Trials
During machine setup, the stroke can be incrementally adjusted to find the optimal actuator travel for a new process, then locked in place, speeding up the commissioning phase.
Is the Airtac SCJ32 Standard Cylinder SCJ32X255-10 the Right Cylinder?
Choose the SCJ32 when you need a compact, adjustable-stroke cylinder for light pushing or clamping. If your force requirements increase, stepping up to the 40 mm bore provides 628 N of push force at the same 0.5 MPa pressure. For applications that don't require stroke adjustment, the fixed-stroke SC series is a simpler, more cost-effective alternative. This SCJ32X255-10 is a direct replacement for any AirTAC SCJ32 with a 255 mm nominal stroke, a 10 mm adjust range, PT ports, and basic mounting.
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 SCJ32X255-10 FAQ
At the standard operating pressure of 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N.
Yes, if you need the ability to adjust the stroke end. The SCJ32X255-10 has the same 32 mm bore and 255 mm nominal stroke as an SC32X255, but adds a 10 mm rear adjustment screw. Ensure your mounting and porting (PT1/8) are compatible.
