About the Airtac SCJ32 Standard Cylinder SCJ32X200-50S
The SCJ32X200-50S is a 32 mm bore double-acting single-rod cylinder that puts field-adjustable stroke control directly on the machine. Its rear-cap adjusting screw provides up to 50 mm of stroke-end reduction, so you can fine-tune the 200 mm nominal stroke during commissioning or format changes without swapping the cylinder. With a 12 mm diameter rod and M10x1.25 rod thread, 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.
A built-in magnet is integrated into the piston, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for reliable end-of-stroke or mid-stroke position sensing. The body length A(SCJ) measures 182 mm, and the PT1/8 port supplies filtered air from 0.15 to 1.0 MPa. Standard adjustable end cushioning decelerates the piston smoothly, while the TPU seal keeps the cylinder working across a -20 to +70 °C ambient range.
Airtac SCJ32 Standard Cylinder SCJ32X200-50S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X200-50S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 200 mm |
| Stroke adjustment | Up to 50 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 SCJ32X200-50S Is Used
Commissioning & Process Tuning
The 50 mm adjustable stroke range lets technicians dial in the exact stroke end position on a new assembly fixture without cutting brackets or shimming hard stops, speeding up line bring-up.
Small-Part Transfer Gates
Fine-tune the gate opening on a packaging conveyor to match different product widths. The 402 N push force at 0.5 MPa is ample for lightweight diverters and sorting paddles.
Sensor-Controlled Clamping
With the built-in magnet and CMSG sensors, the SCJ32X200-50S provides precise clamp-position feedback. The rear screw adjusts clamp depth for varying workpiece thicknesses in light CNC or test fixtures.
Is the Airtac SCJ32 Standard Cylinder SCJ32X200-50S the Right Cylinder?
Step up to the 40 mm bore SCJ40X200-50 if your application needs more force—the 40 mm bore pushes with 628 N at 0.5 MPa, a 56 % increase over the 32 mm bore’s 402 N. If you do not need the adjustable stroke feature, a fixed-stroke SC32X200 cylinder with the same -S magnet option is a simpler, slightly shorter alternative. For a direct replacement, match the 32 mm bore, 200 mm nominal stroke, 50 mm adjust range, PT port thread, basic mounting, and the built-in magnet; the genuine AirTAC SCJ32X200-50S is the exact drop-in part.
At a 200 mm stroke the 12 mm rod is still well supported, but if side loads are present in your application, consider adding an external linear guide or switching 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 (-50)
- ✓ 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 SCJ32X200-50S FAQ
At 0.5 MPa the cylinder produces 402 N pushing and 345 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. The theoretical maximum at 1.0 MPa is 82 kgf. Because it is a single-rod cylinder, push force is always greater than pull force due to the rod area.
A rear-cap adjusting screw lets you shorten the stroke end by up to 50 mm from the 200 mm nominal maximum. It does not change the cylinder’s force or speed. You can replace a fixed-stroke SC32 cylinder with an SCJ32X200-50S only if you have space for the slightly longer body (A=182 mm) and need the field-adjustable range; otherwise, a standard SC32 is a direct dimensional match.
