About the Airtac SCJ32 Standard Cylinder SCJ32X140-30
The SCJ32X140-30 is a 32 mm bore, single-rod double-acting cylinder with a rear-cap adjusting screw that provides up to 30 mm of field-adjustable stroke reduction. This allows the effective stroke to be fine-tuned between 110 mm and the nominal 140 mm without swapping the cylinder, making it ideal for commissioning trials or format changeovers on compact machinery. The push force is 402 N at 0.5 MPa, rising to 724 N at the 0.9 MPa maximum operating pressure.
This tie-rod cylinder uses a 12 mm diameter piston rod with an M10x1.25 rod thread and PT1/8 ports. The standard air cushion length is 21 mm, and the SCJ body length A is 182 mm. It operates on filtered air from 0.15 to 1.0 MPa across a -20 to +70 °C temperature range with the default TPU seal.
Airtac SCJ32 Standard Cylinder SCJ32X140-30 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X140-30 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 140 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 SCJ32X140-30 Is Used
Commissioning & Setup
The 30 mm adjusting screw lets technicians quickly dial in the exact stroke end position during machine commissioning without fabricating custom external hard stops, saving hours of setup time.
Wear Compensation
In clamping or pressing fixtures, the adjustable stroke can be periodically shortened to compensate for tooling or pad wear, maintaining consistent clamping force without replacing the cylinder.
Small Part Stops
Use the SCJ32 on mini-conveyors as an adjustable part stop. The 30 mm range allows operators to reposition the stop point for different product sizes on the fly.
Is the Airtac SCJ32 Standard Cylinder SCJ32X140-30 the Right Cylinder?
Select the SCJ32X140-30 when you need to dial in a precise stroke end position within a 30 mm window. If the 402 N push force at 0.5 MPa is insufficient, stepping up to the 40 mm bore SCJ40 delivers 628 N push. For applications requiring a fixed, non-adjustable stroke, the standard SC32 series is a simpler and more cost-effective alternative. A direct replacement must match the 32 mm bore, 140 mm nominal stroke, 30 mm adjust range, PT1/8 port, and basic mounting style.
For this 140 mm stroke, side-loading is generally not a primary concern on a 32 mm bore, but always ensure the load is guided externally and the rod is not subjected to direct lateral forces to prevent premature seal wear and rod 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 SCJ32X140-30 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The force increases linearly with pressure, reaching a maximum push force of 724 N at the 0.9 MPa operating limit. The pull force is lower because the rod reduces the effective piston area on the return stroke.
Yes, if you need the 30 mm stroke adjustability. The SCJ32X140-30 is a direct dimensional and port replacement for an SC32X140, but the body length A is 182 mm. Ensure your mounting and porting (PT1/8) match. If you do not need the adjustment feature, the standard SC32 is the direct fixed-stroke equivalent.
