About the Airtac SCJ32 Standard Cylinder SCJ32X300-10
The SCJ32X300-10 is a double-acting, single-rod pneumatic cylinder from AirTAC, engineered with a rear-cap adjusting screw that provides 10 mm of field-adjustable stroke-end control. This allows you to fine-tune the piston stop position without removing the cylinder from the machine, making it ideal for commissioning trials or processes that require a precise, repeatable end point. The 32 mm bore generates 402 N of push force at 0.5 MPa, with a 12 mm piston rod and PT1/8 ports.
With a nominal 300 mm stroke, this tie-rod cylinder falls well within the 1000 mm maximum standard stroke for the 32 mm bore. The integrated air cushion, with a 21 mm cushion length, decelerates the piston smoothly at the end of travel, reducing impact and noise. Its compact body length A(SCJ) is 182 mm, and it operates reliably on filtered air at pressures from 0.15 to 1.0 MPa.
Airtac SCJ32 Standard Cylinder SCJ32X300-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X300-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 300 mm |
| Stroke adjustment | Up to 10 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 SCJ32X300-10 Is Used
End-Stop Calibration
The 10 mm adjusting screw allows technicians to precisely calibrate the piston's end position during machine setup, compensating for minor variations in tooling or workpiece placement without altering the PLC program.
Dispensing & Dosing
In small-scale adhesive or fluid dispensing, the adjustable stroke lets you fine-tune the plunger's travel to control the exact volume of material deposited, ensuring consistent shot sizes across production runs.
Wear Compensation
In clamping or pressing fixtures, the stroke can be slightly extended over time to compensate for wear on contact pads or seals, maintaining consistent clamping force without replacing the cylinder or adding shims.
Is the Airtac SCJ32 Standard Cylinder SCJ32X300-10 the Right Cylinder?
Choose the SCJ32X300-10 when your application demands a 300 mm stroke with the ability to dial in the exact end position, eliminating the need for external hard stops. If your force requirements are lower, the next step down in bore is not available in the SCJ series; for higher force, consider stepping up to the SCJ40 series, which delivers 628 N of push force at 0.5 MPa. For applications where the stroke length is fixed and never needs adjustment, the standard SC32X300 fixed-stroke cylinder is a more economical alternative.
For a drop-in replacement, match this model exactly: an AirTAC SCJ32X300-10 with PT ports, basic mounting, and no magnet. For strokes of 300 mm or more, be mindful of side-loading on the 12 mm rod. If your application involves significant lateral force, use an external guide rail or switch to a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ32X300-10 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. Because it is a single-rod cylinder, the push force is greater than the pull force due to the area of the 12 mm rod on the piston's return side.
Yes, the SCJ32X300-10 can replace an SC32X300 if you have the space for the slightly longer rear adjusting screw housing. The mounting footprint, port size (PT1/8), and rod thread (M10x1.25) are identical. Ensure you match the port type (PT), mounting style (basic), and magnet option (none) for a seamless swap.
