About the Airtac SCJ32 Standard Cylinder SCJ32X65-30
The SCJ32X65-30 is a double-acting, single-rod pneumatic cylinder with a 30 mm rear adjusting screw, letting you fine-tune the stroke end position on the fly without swapping the unit. Its 32 mm bore delivers 402 N of push force at 0.5 MPa, making it a compact workhorse for light clamping, sorting, and diverting tasks where the exact end stop needs to be dialed in during commissioning or changeover.
With a 12 mm diameter rod, PT1/8 ports, and a 21 mm air cushion, this tie-rod cylinder is built for reliable cycling in tight spaces. The body length (A dimension) is 182 mm, and the adjustable stroke is ideal for taking up tolerance stack-up or wear in fixtures, ensuring consistent part contact every cycle.
Airtac SCJ32 Standard Cylinder SCJ32X65-30 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X65-30 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 65 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 SCJ32X65-30 Is Used
Commissioning & Setup
The 30 mm adjustment range allows technicians to quickly dial in the perfect end stop for a new fixture or sensor position during machine setup, without needing to swap out the cylinder.
Wear Compensation
In repetitive clamping or pressing operations, the adjustable screw can be used to take up mechanical wear on tooling or contact pads, maintaining consistent force application over time.
Small-Part Sorting Gates
The 32 mm bore provides a light, fast-acting stroke for diverting small components on a conveyor. The adjustable stroke lets you fine-tune the gate opening to match different product sizes.
Is the Airtac SCJ32 Standard Cylinder SCJ32X65-30 the Right Cylinder?
Choose the SCJ32X65-30 when your application needs a stroke that can be precisely shortened by up to 30 mm from the 65 mm nominal maximum. If you need more force, the next step up is the 40 mm bore SCJ40, which provides 628 N of push at 0.5 MPa. For applications where the stroke is permanently fixed and never needs field adjustment, the standard SC32 fixed-stroke cylinder is a more economical choice.
This model is a direct replacement for another AirTAC SCJ32X65-30 with PT ports and basic mounting. When ordering a matching unit, ensure the bore (32 mm), nominal stroke (65 mm), and adjustable range (-30) are identical. For strokes longer than 300 mm, consider an external guide rail to protect the 12 mm rod from side loads and prevent 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 SCJ32X65-30 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N. Because it is a single-rod cylinder, the push force is greater than the pull force.
You can, but the SCJ body is slightly longer to house the adjusting mechanism. The SCJ32X65-30 is a direct fit replacement only for another SCJ32 with a 65 mm nominal stroke and a -30 adjustment range. The port size (PT1/8) and mounting accessories must also match.
