About the Airtac SCJ32 Standard Cylinder SCJ32X200-20S
The SCJ32X200-20S is a double-acting, single-rod tie-rod cylinder that lets you fine-tune the stroke end position by up to 20 mm via the rear adjusting screw—no need to swap the cylinder for minor commissioning changes. With a 12 mm piston rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure), making it a precise actuator for light automation tasks.
This model includes a built-in magnet (-S suffix), so standard CMSG/DMSG/EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for clean end-of-stroke sensing. The 200 mm nominal stroke is well within the 1000 mm maximum for bore 32, and the adjustable air cushion helps decelerate the piston smoothly within its 21 mm cushion length.
Airtac SCJ32 Standard Cylinder SCJ32X200-20S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X200-20S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 200 mm |
| Stroke adjustment | Up to 20 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 SCJ32X200-20S Is Used
Commissioning Fine-Tuning
During machine setup, technicians can dial in the exact 200 mm stroke end position with the 20 mm rear screw, compensating for small fixture variations without re-machining stops.
Small-Part Ejector
Used on a packaging line to push lightweight products off a belt, the adjustable stroke lets operators quickly change the eject distance when switching between box sizes.
Sensor Calibration Jig
Provides a repeatable, fine-tunable linear motion for testing photoelectric sensors, where the 20 mm adjustment range is used to find the precise trigger point.
Is the Airtac SCJ32 Standard Cylinder SCJ32X200-20S the Right Cylinder?
Choose the SCJ32 when you need field-adjustable stroke control in a compact 32 mm bore package. If your force requirement grows, stepping up to the SCJ40 delivers 628 N of push at 0.5 MPa—a 56% increase from the same air pressure. For applications where the stroke is fixed and never needs on-machine tuning, the standard SC32 fixed-stroke cylinder is a simpler, cost-effective alternative. This SCJ32X200-20S is a direct replacement for another AirTAC SCJ32 adjustable cylinder with a 200 mm nominal stroke, 20 mm adjust range, PT ports, and a magnet sensor option.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-20)
- ✓ 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 SCJ32X200-20S FAQ
At 0.5 MPa it generates 402 N pushing and 345 N pulling (due to the 12 mm rod area). At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. Always size for the lower pull force if the cylinder does work in both directions.
Yes, provided the bore, nominal stroke, and port size match. The SCJ32X200-20S has the same envelope as an SC32X200 but adds a rear adjusting screw, so you gain 20 mm of stroke-end adjustability. Ensure you have clearance for the longer rear cap and wire the built-in magnet sensor if your old unit lacked one.
