About the Airtac SCJ100 Standard Cylinder SCJ100X80-100S
The SCJ100X80-100S is a double-acting, single-rod pneumatic cylinder engineered for applications requiring precise, field-adjustable stroke end positioning. With a 100 mm bore and a nominal 80 mm stroke, the rear adjusting screw provides a full 100 mm of adjustment range, allowing operators to fine-tune the retract end position without dismounting the cylinder. At 0.5 MPa, it delivers a substantial 3927 N push force, making it a powerful solution for heavy-duty clamping, pressing, and positioning tasks.
This model features a built-in magnet (suffix -S), enabling direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for reliable, non-contact position feedback. The 25 mm piston rod and PT1/2 port ensure robust flow and force transmission. The body length A(SCJ) is 245 mm, and the adjustable air cushion decelerates the piston smoothly, protecting end caps during high-cycle operation.
Airtac SCJ100 Standard Cylinder SCJ100X80-100S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X80-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 80 mm |
| Stroke adjustment | Up to 100 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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, 29 mm |
| Max stroke | Up to 1500 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SCJ100 Standard Cylinder SCJ100X80-100S Is Used
Commissioning & Setup
Fine-tune the retract end stop during machine commissioning to perfectly align with tooling or fixtures, eliminating the need for shims or custom mechanical stops.
Wear Compensation
Periodically adjust the stroke end to compensate for mechanical wear in grippers or pressing tools, maintaining consistent clamping force and part quality over long production runs.
Format Changeover
Quickly adapt the cylinder stroke for different product sizes on a packaging or sorting line, reducing downtime between batches with a simple screw adjustment.
Is the Airtac SCJ100 Standard Cylinder SCJ100X80-100S the Right Cylinder?
Select the SCJ100X80-100S when you need a high-force actuator with the flexibility to adjust the stroke end point during commissioning or product changeovers. If your application requires even more force, consider stepping up to the 125 mm bore SCJ, which provides 6136 N of push force at 0.5 MPa. For applications where the stroke is fixed and never needs adjustment, the standard SC100 fixed-stroke cylinder offers a more economical alternative. For exact drop-in replacement, match the 100 mm bore, 80 mm nominal stroke, 100 mm adjustment range, PT port thread, and the integrated magnet; this unit mounts with basic tie-rod nuts. For strokes of 300 mm or more, evaluate side-load forces on the 25 mm rod and consider adding an external guide rail to prevent rod bending and premature seal wear.
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 SCJ100 Standard Cylinder SCJ100X80-100S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. The maximum push force at the 0.9 MPa operating limit is 7068 N. Because it is a single-rod cylinder, the push force is always greater than the pull force.
No, the rear adjusting screw only sets the mechanical end stop for the retract stroke. It does not lock the piston rod or hold a load when air pressure is lost. If load holding is required without live pressure, a pilot-operated check valve or external rod brake must be added.
