About the Airtac SCJ32 Standard Cylinder SCJ32X175-30
The SCJ32X175-30 is a double-acting, single-rod pneumatic cylinder that puts stroke-end tuning directly in your hands. Its rear-cap adjusting screw provides a 30 mm field-adjustable range, letting you dial in the exact stop position without removing the cylinder or adding external hard stops. With a 12 mm diameter piston rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa, scaling up to 724 N at the maximum operating pressure of 0.9 MPa.
This 32 mm bore model is built on a proven tie-rod platform with a body length of 182 mm and an adjustable air cushion to decelerate the piston smoothly. The 175 mm nominal stroke is well within the 1000 mm maximum standard stroke for this bore, making it a reliable choice for applications where the stroke length must be precisely matched during commissioning or changed over for different product formats.
Airtac SCJ32 Standard Cylinder SCJ32X175-30 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X175-30 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 175 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 SCJ32X175-30 Is Used
Commissioning & Setup
Ideal for machine builders who need to fine-tune the actuator's end position during initial run-off, accommodating stack-up tolerances in the mechanical assembly without re-machining brackets.
Product Format Changeover
Quickly adjust the cylinder stroke when a packaging line switches between different box sizes, ensuring the pusher or stopper contacts the product at the correct depth every time.
Wear Compensation
As gripper pads or tooling tips wear down over thousands of cycles, the 30 mm adjustment range can be used to recover the precise contact position, extending the service life of consumable components.
Is the Airtac SCJ32 Standard Cylinder SCJ32X175-30 the Right Cylinder?
Choose the SCJ32X175-30 when your machine needs a stroke that can be trimmed by up to 30 mm on the fly. If the 402 N push force at 0.5 MPa is slightly too low, stepping up to the 40 mm bore (SCJ40) provides 628 N. For applications where the stroke is permanently fixed after setup, the standard SC series offers the same mounting and force characteristics without the adjusting mechanism. A direct replacement must match the 32 mm bore, 175 mm nominal stroke, 30 mm adjust range, PT port thread, and basic mounting. For strokes of this length, ensure the rod is aligned with the load to prevent bending; an external guide rail is recommended if side forces are present.
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 SCJ32X175-30 FAQ
At the standard operating pressure of 0.5 MPa, this single-rod cylinder generates 402 N of push force and 345 N of pull force due to the rod area differential. The maximum push force at 0.9 MPa is 724 N.
Yes, if you need the ability to shorten the stroke end by up to 30 mm. The SCJ32 shares the same 32 mm bore, tie-rod construction, and mounting accessories as the SC series. Ensure the nominal stroke, port size (PT1/8), and magnet option match your existing setup.
