About the Airtac SCJ32 Standard Cylinder SCJ32X500-30S
The SCJ32X500-30S is a double-acting, single-rod tie-rod cylinder that puts stroke-end fine-tuning directly on the machine. Its rear adjusting screw provides a 30 mm adjustable range, letting you dial in the exact stop position without swapping the cylinder. With a 12 mm piston rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa, scaling up to 724 N at the maximum operating pressure of 0.9 MPa.
A built-in magnet (the -S suffix) allows CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for reliable, non-contact position sensing. The body length A(SCJ) is 182 mm, and the standard 21 mm air cushion decelerates the piston smoothly at stroke end. This model is rated for a 500 mm nominal stroke, which is within the 1000 mm maximum standard stroke for the 32 mm bore.
Airtac SCJ32 Standard Cylinder SCJ32X500-30S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X500-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 30 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 SCJ32X500-30S Is Used
Commissioning & Setup
Fine-tune the end-stop by up to 30 mm during initial machine commissioning to perfectly align the actuator with mating tooling or fixtures, eliminating the need for shims.
Wear Compensation
Adjust the stroke end to take up mechanical wear on contact surfaces or tooling over time, maintaining consistent process quality without replacing the cylinder.
Format Changeovers
Quickly adapt the stroke end position for different product sizes or batch runs on a packaging or assembly line, reducing downtime between changeovers.
Is the Airtac SCJ32 Standard Cylinder SCJ32X500-30S the Right Cylinder?
Choose the SCJ32 when you need a compact, adjustable-stroke actuator in the 402 N push class at 0.5 MPa. If your application requires more force, stepping up to the SCJ40 provides 628 N of push at the same pressure. For applications that do not require field adjustability, the fixed-stroke SC32 offers a simpler, more cost-effective solution. When replacing an existing unit, match the bore, the 500 mm nominal stroke, the 30 mm adjust range, PT port thread, and the integrated magnet to ensure full compatibility with your sensor setup.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ32X500-30S FAQ
A screw in the rear cap lets you shorten the stroke end by up to 30 mm from the nominal 500 mm maximum. This sets a new mechanical stop for the piston, allowing precise field adjustment without changing the cylinder's bore or force output.
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The force increases linearly with pressure, reaching 724 N of push force at the maximum operating pressure of 0.9 MPa.
