About the Airtac SCJ32 Standard Cylinder SCJ32X200-40S
The SCJ32X200-40S is a compact double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, letting you fine-tune the 200 mm nominal stroke by up to 40 mm without replacing the unit. With a 12 mm diameter rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa, scaling to 724 N at the maximum operating pressure of 0.9 MPa.
This model includes a built-in magnet, so CMSG, DMSG, or EMSG solid-state sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. Its 21 mm air cushion decelerates the piston quietly at both ends, and the body length A is 182 mm, making it a genuine AirTAC solution for space-constrained, high-cycle applications.
Airtac SCJ32 Standard Cylinder SCJ32X200-40S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X200-40S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 200 mm |
| Stroke adjustment | Up to 40 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 SCJ32X200-40S Is Used
Commissioning & Setup
Fine-tune the actuator end-stop by up to 40 mm during machine commissioning without swapping cylinders or machining custom stops, dramatically reducing setup time.
Wear Compensation
In high-cycle clamping or pressing fixtures, the adjusting screw compensates for pad or tooling wear, maintaining consistent contact force and part quality over long production runs.
Part-Present Sensing
The built-in magnet enables precise, non-contact position feedback via CMSG/DMSG sensors, confirming full extension or retraction for part-transfer and sorting gates.
Is the Airtac SCJ32 Standard Cylinder SCJ32X200-40S the Right Cylinder?
Choose the SCJ32X200-40S when you need to dial in a precise stroke end position during commissioning or after tooling wear, and the 32 mm bore's force profile is sufficient. If you require more push force, step up to the SCJ40 series, which provides 628 N at 0.5 MPa. For applications where the stroke is permanently fixed, the standard SC32X200 is a simpler, non-adjustable alternative. This cylinder is a direct replacement for another AirTAC SCJ32 adjustable-stroke unit with a 200 mm nominal stroke, a 40 mm adjustment range, PT ports, basic mounting, and a magnet.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-40)
- ✓ 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 SCJ32X200-40S FAQ
The push force at 0.5 MPa is 402 N, and the pull force on the return stroke is 345 N due to the 12 mm rod reducing the effective piston area. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N.
A rear-cap adjusting screw limits the piston's extension stroke end within a 40 mm range. You set the exact stop point you need. If you lock the screw at the full 200 mm position, it functions like a fixed-stroke SC cylinder, but the SCJ body is slightly longer to accommodate the mechanism.
