About the Airtac SCJ32 Standard Cylinder SCJ32X130-30S
The SCJ32X130-30 is a double-acting, single-rod AirTAC cylinder that puts a 30 mm adjustable stroke range at your fingertips via a rear-cap screw. With a 12 mm diameter rod and PT1/8 ports, this tie-rod design delivers 402 N of push force at 0.5 MPa, scaling up to 724 N at 0.9 MPa. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
The 21 mm air cushion at each end decelerates the piston smoothly, protecting your tooling during high-speed cycles. Because the stroke end is field-adjustable, you can fine-tune the stopping position without removing the cylinder or adding external hard stops—ideal for commissioning trials or format changes on compact automation cells.
Airtac SCJ32 Standard Cylinder SCJ32X130-30S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X130-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 130 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 SCJ32X130-30S Is Used
Commissioning & Setup
The 30 mm rear adjuster lets technicians dial in the exact stroke end on a new machine without iterative disassembly, slashing setup time during factory acceptance tests.
Small-Part Diverting
Fine-tune the push-off point on a packaging line diverter. The 402 N force at 0.5 MPa easily handles lightweight carton sorting, while the sensor magnet confirms each cycle.
Wear Take-Up
In cyclic pressing or clamping, the adjustable screw compensates for pad wear over time, maintaining consistent contact force without reprogramming the PLC or changing the cylinder.
Is the Airtac SCJ32 Standard Cylinder SCJ32X130-30S the Right Cylinder?
Step up to a 40 mm bore SCJ40 series if your application demands more than the 724 N maximum push this 32 mm unit provides at 0.9 MPa; the SCJ40 delivers 628 N at just 0.5 MPa. If you never need to alter the stroke after initial setup, a fixed-stroke SC32 cylinder offers the same mounting envelope and force characteristics without the adjusting mechanism. For a direct replacement, match the 32 mm bore, 130 mm nominal stroke, 30 mm adjust range, PT port thread, and the -S magnet option. This cylinder uses the basic mounting style; add FA or LB brackets from the F-SC32 accessory range if a front flange or foot mount is needed later.
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 SCJ32X130-30S FAQ
At 0.5 MPa, the cylinder provides 402 N pushing and 345 N pulling. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 804 N (82 kgf).
Yes, if you need field-adjustable stroke. The SCJ32 shares the same 32 mm bore, 12 mm rod, and PT1/8 ports. Ensure the 130 mm nominal stroke and 30 mm adjust range fit your space, as the SCJ body is slightly longer than the fixed-stroke SC.
