About the Airtac SCJ32 Standard Cylinder SCJ32X275-10S
The SCJ32X275-10S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke, giving you 10 mm of fine-tuning at the stroke end via a rear-cap adjusting screw. With a 32 mm bore and a 12 mm rod, it delivers 402 N of push force at 0.5 MPa, making it a compact yet capable actuator for light positioning and clamping tasks.
This model includes a built-in magnet (suffix -S), so you can directly mount CMSG/DMSG/EMSG reed or solid-state sensors on the tie-rod barrel for reliable end-of-stroke detection. The body length A(SCJ) is 182 mm, and the standard PT1/8 ports keep plumbing simple. Its TPU seals work from -20 to +70 °C.
Airtac SCJ32 Standard Cylinder SCJ32X275-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X275-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 275 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 SCJ32X275-10S Is Used
Commissioning Fine-Tuning
During machine setup, use the 10 mm adjustment screw to dial in the exact stroke end position without re-plumbing or swapping cylinders, saving hours of trial-and-error.
Light-Part Clamping
Adjust the stroke end to accommodate varying workpiece thicknesses in a light-duty clamping fixture, preventing part damage from over-travel while maintaining 402 N of holding force.
Wear Compensation
As tooling or gripper pads wear over time, the adjustable stroke lets you take up the slack mechanically, restoring full engagement without reprogramming the controller.
Is the Airtac SCJ32 Standard Cylinder SCJ32X275-10S the Right Cylinder?
Choose this 32 mm bore when your application needs up to 402 N of push force at standard plant air. If you require more force, step up to the 40 mm bore SCJ, which provides 628 N at the same pressure. For applications where the stroke never needs adjustment, the fixed-stroke SC32 series is a simpler, cost-effective alternative. A genuine replacement must match the SCJ32 bore, 275 mm nominal stroke, 10 mm adjustment range, PT ports, and the magnet option.
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 SCJ32X275-10S FAQ
The theoretical push force at 0.5 MPa is 402 N, and the pull force on the rod side is 345 N. This difference is due to the 12 mm rod reducing the piston area on the return stroke. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 804 N.
Yes, provided the mounting and porting match. The SCJ body is slightly longer to house the adjusting screw, so check the 182 mm A-length against your space. You must also match the 275 mm nominal stroke, PT1/8 ports, and ensure you need the -S magnet for your sensors.
