About the Airtac SCJ32 Standard Cylinder SCJ32X100-30S
The SCJ32X100-30S delivers 402 N of push force at 0.5 MPa, making it a capable compact actuator for light industrial tasks. Its 30 mm rear adjusting screw lets you fine-tune the stroke end position on the fly—ideal for commissioning trials or taking up mechanical wear without swapping the cylinder. The 12 mm piston rod and PT1/8 ports keep the footprint small while the 21 mm air cushion protects the end caps.
This model includes a built-in magnet, so standard CMSG or DMSG sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke sensing. The double-acting, single-rod design provides a genuine 345 N pull force, and the TPU seals handle a standard temperature range of -20 to +70 °C. It is a direct, field-adjustable replacement for another SCJ32X100-30S with PT threads and basic mounting.
Airtac SCJ32 Standard Cylinder SCJ32X100-30S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 30 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 SCJ32X100-30S Is Used
Commissioning & Setup
The 30 mm adjuster lets technicians dial in the precise end-stop during machine setup without cutting rails or adding external hard stops, speeding up line commissioning.
Small-Part Diverter Gates
Fine-tune the gate opening on a conveyor junction. The adjustable stroke compensates for guide rail alignment variations, ensuring smooth product transfer with 402 N of push force.
Wear Compensation on Clamps
On a repetitive clamping fixture, use the rear screw to gradually extend the stroke as gripper pads wear down, maintaining consistent clamping pressure without immediate pad replacement.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-30S the Right Cylinder?
Step up to the SCJ40 bore if your application demands a stronger push force; the 40 mm bore provides 628 N at 0.5 MPa. For a simpler, fixed-stroke solution where no field adjustment is needed, the standard SC32X100 is a direct dimensional match. This SCJ32X100-30S is the correct replacement when you need to preserve the exact 30 mm adjustable range, the built-in magnet for sensor feedback, and the PT port threads. For strokes over 300 mm on this 32 mm bore, consider an external guide rail to protect the 12 mm rod from side-load deflection.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ32X100-30S FAQ
At 0.5 MPa, the cylinder provides 402 N of push force and 345 N of pull force. The maximum push force at the 0.9 MPa operating limit is 724 N. The rear adjusting screw changes only the stroke end position, not the force output.
It can replace an SC32X100 if you need the 30 mm field-adjustable stroke feature and have clearance for the slightly longer rear screw housing. You must match the PT port threads, the basic mounting style, and the magnet option (S) to ensure full sensor compatibility.
