About the Airtac SCJ32 Standard Cylinder SCJ32X75-75
The SCJ32X75-75 is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that provides a full 75 mm of field-adjustable stroke-end control. With a 32 mm bore and 12 mm rod, it delivers 402 N of push force at 0.5 MPa (724 N at 0.9 MPa), making it a compact solution for light automation tasks where the stroke must be dialled in precisely during commissioning or changeover.
Its tie-rod construction keeps the 182 mm body length consistent, while the PT1/8 port and M10x1.25 rod thread integrate easily into standard pneumatic circuits. The 21 mm air cushion decelerates the piston quietly, and the adjusting screw lets you shorten the nominal 75 mm stroke anywhere within its 75 mm range to match the exact machine stop position.
Airtac SCJ32 Standard Cylinder SCJ32X75-75 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X75-75 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 75 mm |
| Stroke adjustment | Up to 75 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 SCJ32X75-75 Is Used
Commissioning & Setup
Dial in the exact end-stop position during machine bring-up without fabricating external hard stops. The 75 mm adjustment range covers wide setup tolerances.
Product Format Changeover
Quickly adapt the stroke for different box sizes or product widths on a packaging line by turning the rear screw, eliminating mechanical change parts.
Wear Compensation
Take up mechanical play or seal wear over time by fine-tuning the stroke end, maintaining consistent actuator positioning without replacing the cylinder.
Is the Airtac SCJ32 Standard Cylinder SCJ32X75-75 the Right Cylinder?
Choose this 32 mm bore when your application needs up to 402 N of push force at standard shop air. If you require more force, stepping up to the SCJ40 series provides 628 N push at 0.5 MPa. For applications where the stroke never changes, the fixed-stroke SC32 cylinder is a simpler, lower-cost alternative. The SCJ32X75-75 directly replaces any AirTAC SCJ32 adjustable-stroke cylinder of the same 75 mm nominal stroke and 75 mm adjust range with PT ports and basic mounting.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-75)
- ✓ 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 SCJ32X75-75 FAQ
At 0.5 MPa it produces 402 N pushing and 345 N pulling (the difference is due to the 12 mm single rod). At the maximum operating pressure of 0.9 MPa, push force reaches 724 N.
A screw in the rear cap sets the piston's end position, letting you shorten the stroke by up to 75 mm from the nominal 75 mm maximum. It adjusts the stroke length only, not the force or speed.
