About the Airtac SCJ32 Standard Cylinder SCJ32X80-30S
The SCJ32X80-30S is a compact 32 mm bore adjustable-stroke air cylinder that delivers 402 N of push force at 0.5 MPa, with a 12 mm diameter piston rod. Its rear-cap adjusting screw provides up to 30 mm of field-adjustable stroke-end reduction, letting you fine-tune the piston stop position without removing the cylinder from the machine.
This model includes a built-in magnet (-S suffix), so standard CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. The body length A(SCJ) is 182 mm, and the cylinder uses PT1/8 ports with an M10x1.25 rod thread. It operates on filtered air from 0.15 to 1.0 MPa across a -20 to +70 °C temperature range.
Airtac SCJ32 Standard Cylinder SCJ32X80-30S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X80-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 80 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 SCJ32X80-30S Is Used
Commissioning & Setup
The 30 mm stroke-end adjustment lets technicians dial in the exact stopping position during machine commissioning, accommodating small build tolerances without fabricating custom shims or hard stops.
Small-Part Eject & Sorting
Fine-tune the eject stroke on a sorting conveyor for different component heights. The built-in magnet enables clean sensor feedback to the PLC for high-speed counting and verification.
Wear Compensation
In clamping or pressing fixtures, the adjustable screw can be advanced over time to compensate for pad wear or material compression, maintaining consistent clamping force without reprogramming the machine.
Is the Airtac SCJ32 Standard Cylinder SCJ32X80-30S the Right Cylinder?
Choose the SCJ32 when you need a light-duty adjustable stroke up to 1000 mm. If more force is required, step up to the SCJ40 bore which provides 628 N of push force at the same 0.5 MPa pressure. For applications that do not require stroke adjustment, the fixed-stroke SC32 series offers a simpler, lower-cost alternative with the same mounting footprint. This SCJ32X80-30S is a direct replacement for any AirTAC SCJ32 cylinder with an 80 mm nominal stroke and 30 mm adjustment range, provided the port thread (PT) and magnet option match. For strokes of 300 mm or longer, evaluate side-load conditions and consider an external guide rail or a guided cylinder to protect the 12 mm rod from bending.
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 SCJ32X80-30S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. Because this is a single-rod cylinder, push force is always greater than pull force due to the rod area on the return side.
Yes, if you need field-adjustable stroke control. The SCJ32X80-30S shares the same 32 mm bore, PT1/8 ports, and basic mounting dimensions as the SC32 series, but adds a rear adjusting screw for up to 30 mm of stroke-end reduction. Ensure your machine has clearance for the slightly longer SCJ body length of 182 mm.
