About the Airtac SCJ32 Standard Cylinder SCJ32X200-40
The SCJ32X200-40 is a 32 mm bore double-acting single-rod cylinder with a rear-cap adjusting screw that provides up to 40 mm of field-adjustable stroke-end reduction. With a 12 mm rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa, making it a precise solution for light-duty positioning tasks where the end stop must be dialed in during commissioning or changeover.
The tie-rod construction houses an adjustable air cushion (21 mm) to decelerate the piston smoothly. The body length A(SCJ) is 182 mm, and the nominal 200 mm stroke is well within the 1000 mm maximum standard stroke for this bore, ensuring ready availability without a non-standard order.
Airtac SCJ32 Standard Cylinder SCJ32X200-40 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X200-40 |
|---|---|
| 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 SCJ32X200-40 Is Used
Commissioning Fine-Tuning
During machine setup, the 40 mm adjustable screw lets technicians dial in the exact end-of-stroke position for a pick-and-place actuator without swapping hard stops or reprogramming offsets.
Wear Take-Up on Stops
In a small diverting gate on a conveyor, the stroke end can be incrementally adjusted to compensate for mechanical wear on the gate stop, maintaining a consistent seal over thousands of cycles.
Format Changeover
For a light-duty labeling head that handles two box sizes, operators can quickly adjust the stroke end by up to 40 mm to match the new format, reducing changeover time without any cylinder disassembly.
Is the Airtac SCJ32 Standard Cylinder SCJ32X200-40 the Right Cylinder?
Choose the SCJ32 when you need to fine-tune the stroke end by up to 40 mm on a compact 32 mm bore platform. If the 402 N push force at 0.5 MPa is insufficient, stepping up to the SCJ40 provides 628 N of push force. For applications that do not require field adjustability, the fixed-stroke SC32 offers a simpler, more cost-effective alternative. A direct replacement must match the 32 mm bore, 200 mm nominal stroke, 40 mm adjust range, PT1/8 port thread, and basic mounting configuration.
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 SCJ32X200-40 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
You can replace an SC32 with an SCJ32X200-40 if you need the 40 mm field-adjustable stroke feature and your application can accommodate the slightly longer body length. The mounting, port size (PT1/8), and force characteristics are identical, but ensure the rear adjusting screw has clearance in your machine.
