About the Airtac SCJ32 Standard Cylinder SCJ32X160-30
The SCJ32X160-30 is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that provides up to 30 mm of field-adjustable stroke reduction. With a 32 mm bore, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it a compact solution for light automation tasks where the end-stop position needs occasional fine-tuning without replacing the cylinder.
This model has a 12 mm diameter piston rod with an M10x1.25 rod thread and a PT1/8 port. The adjustable air cushion is 21 mm long, and the SCJ body length is 182 mm, which is slightly longer than a fixed-stroke SC of the same nominal dimensions to accommodate the rear screw mechanism.
Airtac SCJ32 Standard Cylinder SCJ32X160-30 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X160-30 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 160 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 SCJ32X160-30 Is Used
Commissioning Fine-Tuning
Adjust the stroke end by up to 30 mm on the machine during initial setup to perfectly align the actuator with mating parts without needing shims or custom spacers.
Wear Compensation
In light-duty clamping or pressing fixtures, the screw can be advanced periodically to take up mechanical slack caused by pad wear, maintaining consistent clamp force.
Small-Part Sorting Gates
Fine-tune the opening stroke of a diverter gate on a conveyor for different product sizes, using the 30 mm range to handle multiple SKUs with a single cylinder model.
Is the Airtac SCJ32 Standard Cylinder SCJ32X160-30 the Right Cylinder?
Select the SCJ32X160-30 when you need to dial in a precise stroke end during commissioning or changeovers. If 402 N of push force is insufficient, stepping up to the SCJ40 series provides 628 N at the same pressure. For applications requiring a fixed, non-adjustable stroke, the standard SC32 series is a more economical choice. A direct replacement must match the 32 mm bore, 160 mm nominal stroke, 30 mm adjust range, and PT port thread.
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 SCJ32X160-30 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 402 N and the pull force is 345 N due to the 12 mm rod reducing the piston area on the return stroke. The maximum push force at 0.9 MPa is 724 N.
Yes, if you need the 30 mm adjustable stroke feature. The SCJ32X160-30 has the same bore, nominal stroke, and port size, but the body is longer (182 mm) to house the adjusting screw. Ensure the extra length fits your machine envelope.
