About the Airtac SCJ32 Standard Cylinder SCJ32X200-30
The SCJ32X200-30 is a double-acting, single-rod tie-rod cylinder with a 30 mm rear-cap adjusting screw, letting you fine-tune the stroke end position anywhere within that range without replacing the unit. With a 32 mm bore and a 12 mm rod, it delivers 402 N of push force at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa, making it a compact workhorse for light automation tasks.
The body length A(SCJ) is 182 mm plus the nominal stroke, and the PT1/8 port with M10x1.25 rod thread simplifies plumbing and tooling attachment. Its 21 mm air cushion decelerates the piston smoothly at both ends, protecting the end caps during high-cycle operation. This model is a genuine AirTAC adjustable-stroke cylinder, ideal for applications where the final stop position needs on-machine tweaking.
Airtac SCJ32 Standard Cylinder SCJ32X200-30 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X200-30 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 200 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 SCJ32X200-30 Is Used
Commissioning & Setup
Fine-tune the end-of-stroke position during machine commissioning to perfectly align a pusher or stop without machining custom spacers or brackets.
Small-Part Diverter Gates
Adjust the gate opening on a conveyor line for different product sizes. The 30 mm range allows quick changeover between small batches without stopping production for a cylinder swap.
Wear Compensation in Clamping
In a light-duty clamping fixture, use the adjusting screw to take up mechanical wear on the clamp pad over thousands of cycles, maintaining consistent clamping force.
Is the Airtac SCJ32 Standard Cylinder SCJ32X200-30 the Right Cylinder?
Choose the SCJ32 when your application requires a push force up to 402 N at standard plant air. If you need more force, stepping up to the SCJ40 provides 628 N of push at the same 0.5 MPa. For applications where the stroke length is fixed and never needs field adjustment, the standard SC32 fixed-stroke cylinder is a simpler, more economical alternative. This SCJ32X200-30 is a direct replacement for any AirTAC SCJ32 with a 200 mm nominal stroke and a 30 mm adjustment range, using PT ports and basic mounting.
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 SCJ32X200-30 FAQ
The rear cap has an adjusting screw that acts as a movable end stop for the piston. By turning the screw, you can shorten the stroke end by up to 30 mm from the nominal 200 mm maximum. This adjusts the physical stopping position, not the air pressure or speed.
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 increases to 724 N. The pull force is lower because the rod reduces the effective piston area on the return stroke.
