About the Airtac SCJ32 Standard Cylinder SCJ32X30-30S
The SCJ32X30-30S is a 32 mm bore, double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end. A rear-cap adjusting screw lets you fine-tune the stroke by up to 30 mm, making it ideal for commissioning and format changeovers on compact machinery. At 0.5 MPa, it delivers 402 N of push force and 345 N on the pull stroke, with a 12 mm diameter piston rod.
The built-in magnet (S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for reliable end-of-stroke detection. It uses PT1/8 ports and an M10x1.25 rod thread, with a 21 mm air cushion for smooth deceleration. The body length A(SCJ) is 182 mm, providing a compact footprint for space-constrained applications.
Airtac SCJ32 Standard Cylinder SCJ32X30-30S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X30-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 30 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 SCJ32X30-30S Is Used
Commissioning & Fine-Tuning
The 30 mm adjustment range allows engineers to dial in the exact stroke end position on a new machine without swapping cylinders or machining external hard stops.
Small Part Ejectors
Used on packaging lines to push lightweight products off a conveyor. The adjustable stroke lets operators quickly change the push distance for different box sizes.
Wear Take-Up on Clamps
In light-duty clamping fixtures, the adjusting screw compensates for jaw or pad wear over time, maintaining consistent clamping position without reprogramming the PLC.
Is the Airtac SCJ32 Standard Cylinder SCJ32X30-30S the Right Cylinder?
Choose the SCJ32 when you need a compact, adjustable-stroke actuator with up to 402 N of push force at 0.5 MPa. If your load requires more force, step up to the SCJ40, which provides 628 N of push force at the same pressure. For applications where the stroke is fixed and will never need field adjustment, the standard SC32 fixed-stroke cylinder is a simpler, cost-effective alternative. This model is a direct replacement for another AirTAC SCJ32X30-30S with the same bore, nominal stroke, 30 mm adjust range, PT ports, and built-in magnet.
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 SCJ32X30-30S FAQ
At the standard 0.5 MPa operating pressure, this cylinder provides 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N. Because it is a single-rod cylinder, the push force is always greater than the pull force due to the rod area.
Yes, this is a genuine AirTAC SCJ32 adjustable-stroke cylinder. It is a direct dimensional and performance match for any SCJ32 with a 30 mm nominal stroke, a 30 mm adjust range, PT ports, and a built-in magnet. Always verify your mounting style—this is the basic version without additional brackets.
