About the Airtac SCJ32 Standard Cylinder SCJ32X100-100S
The SCJ32X100-100S is a compact double-acting, single-rod pneumatic cylinder with a 32 mm bore and a nominal 100 mm stroke. Its defining feature is a rear-cap adjusting screw that provides a full 100 mm of stroke-end reduction, allowing the effective stroke to be dialed from 0 to 100 mm directly on the machine. This model includes a built-in magnet (-S suffix), enabling direct mounting of CMSG/DMSG/EMSG sensors for precise, non-contact end-of-stroke detection.
With a push force of 402 N at 0.5 MPa and a 12 mm diameter piston rod, this cylinder is well-suited for light clamping, sorting, and diverting tasks. The adjustable cushion, with a 21 mm length, ensures quiet and reliable deceleration. The PT1/8 port and M10x1.25 rod thread make it a direct fit for standard AirTAC fittings and accessories.
Airtac SCJ32 Standard Cylinder SCJ32X100-100S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 100 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 SCJ32X100-100S Is Used
Commissioning & Fine-Tuning
The 100 mm adjustment range allows engineers to precisely dial in the optimal stroke length during machine setup without swapping cylinders or machining external hard stops, saving significant commissioning time.
Product Format Changeover
On a packaging line, the stroke can be quickly adjusted to handle different box sizes or product positions. The built-in magnet provides sensor confirmation of the new stroke end, ensuring reliable operation after each change.
Wear Compensation in Clamping
In a light-duty clamping fixture, the adjusting screw can be used to take up mechanical wear on a contact pad over time. The 402 N push force is ideal for holding parts during assembly or marking without causing damage.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-100S the Right Cylinder?
For applications needing more force, the next step up is the SCJ40 series, which delivers 628 N of push force at the same 0.5 MPa pressure. If your task requires a fixed, non-adjustable stroke, the standard SC32 series is a simpler, more cost-effective alternative. For this specific SCJ32X100-100S, a direct replacement must match the 32 mm bore, 100 mm nominal stroke, 100 mm adjustment range, PT port thread, and the built-in magnet for sensor compatibility.
For this 100 mm stroke length, side-loading is generally not a major concern if the load is guided. However, if the rod is pushing an unguided mass, even minor misalignment can cause premature seal wear. In such cases, consider adding an external linear guide or switching to a guided cylinder to protect the rod bearing.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ32X100-100S FAQ
At the standard operating pressure of 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N. The pull force is lower because the 12 mm piston rod reduces the effective piston area on the return stroke.
Yes, you can replace an SC32X100 with this SCJ32X100-100S if you need the ability to shorten the stroke. The mounting dimensions and body length are compatible, though the SCJ body is slightly longer to house the adjusting mechanism. Ensure your replacement matches the port type (PT), and note this model includes a magnet for sensors.
