About the Airtac SCJ32 Standard Cylinder SCJ32X100-100
The SCJ32X100-100 is a 32mm bore double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end. Its rear adjusting screw provides a full 100mm of stroke reduction, allowing you to fine-tune the cylinder's end position from 0mm up to its 100mm nominal maximum without dismounting the unit. This model delivers 402N of push force and 345N of pull force at 0.5MPa, making it a compact workhorse for light positioning tasks.
Built on the proven SC tie-rod platform, this SCJ variant adds an M10x1.25 rod thread and PT1/8 ports. The integrated air cushion (21mm length) decelerates the piston quietly at the end of travel. The body length A is 182mm, and the standard operating speed range is 30-800 mm/s. This basic configuration uses a TPU seal, PT threads, and no magnet, keeping it simple and cost-effective for general-purpose use.
Airtac SCJ32 Standard Cylinder SCJ32X100-100 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-100 |
|---|---|
| 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 SCJ32X100-100 Is Used
Commissioning & Setup
Ideal for machine builders who need to dial in the exact stroke during initial setup. The 100mm adjustment range allows for precise mechanical tuning of the end position without swapping cylinders or machining custom stops.
Small Part Ejectors
Used on packaging lines where the push distance for ejecting different-sized cartons changes with each batch. Operators can quickly adjust the stroke end to suit a new box format without tools.
Wear Take-Up in Clamping
In light-duty clamping fixtures, the adjustable stroke compensates for pad wear over time. The screw is simply turned to restore full clamping pressure without replacing the cylinder or the tooling.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-100 the Right Cylinder?
Choose the SCJ32 when your application needs a compact, adjustable end-stop within a 100mm window. If you require higher force, stepping up to the SCJ40 provides 628N of push force at the same 0.5MPa pressure. For applications where the stroke is fixed and will never need field adjustment, the standard SC32 fixed-stroke cylinder is a simpler, more economical alternative. This SCJ32X100-100 is a direct replacement for any AirTAC SCJ32 cylinder with the same 100mm nominal stroke, 100mm adjustment range, PT ports, basic mounting, and no magnet.
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 SCJ32X100-100 FAQ
At the standard operating pressure of 0.5 MPa, this single-rod cylinder produces 402N of push force and 345N of pull force. The push force is higher because it acts on the full 32mm bore area, while the pull force is reduced by the 12mm rod area. At the maximum operating pressure of 0.9 MPa, the push force reaches 724N.
Yes, if you need the adjustable stroke feature. The SCJ32X100-100 has the same 32mm bore, PT1/8 ports, and M10x1.25 rod thread as an SC32. The body length is slightly longer to accommodate the adjusting screw, but the mounting footprint for basic, FA, and LB accessories is identical. Ensure your machine can accept the slightly longer body length A of 182mm.
