About the Airtac SCJ32 Standard Cylinder SCJ32X200-75
The SCJ32X200-75 is a 32 mm bore double-acting single-rod cylinder that puts field-adjustable stroke control directly on the machine. A rear-cap adjusting screw lets you shorten the stroke end by up to 75 mm, so the effective stroke can be tuned anywhere from 125 mm to the full 200 mm without changing the cylinder body. At 0.5 MPa it delivers 402 N push and 345 N pull, making it a compact workhorse for light clamping, sorting, and diverting tasks.
This model uses a 12 mm diameter piston rod with an M10x1.25 rod thread and PT1/8 ports. The adjustable air cushion is 21 mm long, and the SCJ body length A is 182 mm—slightly longer than a fixed-stroke SC of the same bore to house the adjustment mechanism. The standard TPU seal keeps it running from -20 to +70 °C on 40 µm filtered air.
Airtac SCJ32 Standard Cylinder SCJ32X200-75 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X200-75 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 200 mm |
| Stroke adjustment | Up to 75 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 SCJ32X200-75 Is Used
Commissioning & Setup Trials
Dial in the exact stroke end position during machine bring-up without swapping cylinders or machining custom stops. The 75 mm adjustment range covers a wide window for sensor and tooling placement.
Small-Part Eject & Sort Gates
Fine-tune the gate opening stroke to match different component heights on a mixed-product line. The 402 N push force at 0.5 MPa handles light diverting and ejection reliably.
Wear Take-Up on Clamp Fixtures
Compensate for pad wear or material thickness changes over a production run by adjusting the stroke end screw, maintaining consistent clamping pressure without reprogramming the PLC.
Is the Airtac SCJ32 Standard Cylinder SCJ32X200-75 the Right Cylinder?
Step up to a 40 mm bore (628 N push at 0.5 MPa) if the 402 N push force is marginal for your load; step down to a 25 mm bore SC series if you need a smaller footprint and can accept a fixed stroke. The SCJ is the right pick when your process needs frequent stroke-end tweaks—commissioning a new sensor bracket, accommodating part tolerance drift, or running multiple product heights on one line. For a direct replacement, match an SCJ32 with a 200 mm nominal stroke, -75 adjust range, PT1/8 ports, and the same basic mounting.
At 200 mm stroke, the 12 mm rod is relatively slender. If the load applies any side force, add 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 (-75)
- ✓ 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 SCJ32X200-75 FAQ
At 0.5 MPa supply pressure the push force is 402 N and the pull force is 345 N. Push force uses the full 32 mm bore area; pull force subtracts the 12 mm rod area. At the maximum operating pressure of 1.0 MPa, theoretical push force reaches 804 N.
Yes, if you need the adjustable stroke feature. The SCJ32X200-75 has the same bore, rod, port, and mounting interfaces as an SC32, but the body is slightly longer (A=182 mm) to house the rear adjusting screw. Ensure your machine has clearance for the extra length and that the -75 mm adjustment range covers your stroke reduction needs.
