About the Airtac SCJ80 Standard Cylinder SCJ80X100-10
The SCJ80X100-10 is an 80 mm bore double-acting single-rod cylinder delivering 2513 N of push force at 0.5 MPa, with a 25 mm diameter rod for robust linear actuation. Its rear-cap adjusting screw provides a 10 mm field-adjustable range, letting you fine-tune the stroke end position without removing the cylinder from the machine.
With a 28 mm air cushion and a body length A of 239 mm, this tie-rod cylinder decelerates loads smoothly near the stroke end. The PT3/8 port and M20x1.5 rod thread suit standard pneumatic connections, and the maximum push force reaches 4523 N at 0.9 MPa for demanding positioning tasks.
Airtac SCJ80 Standard Cylinder SCJ80X100-10 Technical Specifications
| Model | Airtac SCJ80 Standard Cylinder SCJ80X100-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø80 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 10 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT3/8 |
| 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, 28 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SCJ80 Standard Cylinder SCJ80X100-10 Is Used
Commissioning Fine-Tuning
The 10 mm screw adjustment lets technicians dial in the perfect end-stop during initial machine setup, eliminating the need for shims or external hard stops.
Wear Take-Up on Stops
Compensate for pad or stop wear over time by slightly extending the stroke end with the rear screw, maintaining consistent part positioning on packaging lines.
Format Changeover
Quickly adjust the cylinder stroke for different product sizes in a fixture, reducing downtime when switching between batches on an assembly station.
Is the Airtac SCJ80 Standard Cylinder SCJ80X100-10 the Right Cylinder?
Choose the SCJ80X100-10 when you need to dial in the exact stroke end during commissioning or format changes. If 2513 N at 0.5 MPa is insufficient, stepping up to the 100 mm bore provides 3927 N push; if it exceeds your requirement, the 63 mm bore offers 1559 N. For applications needing a fixed, non-adjustable stroke, the standard SC80X100 is the direct alternative.
A genuine replacement must match the 80 mm bore, 100 mm nominal stroke, 10 mm adjust range, and PT thread. This model uses a basic mount; if you need a pivoting mount, select the TC centre trunnion option. For strokes of 300 mm or more, evaluate side-load forces and consider an external guide or guided cylinder to protect the rod from bending.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ80 Standard Cylinder SCJ80X100-10 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N pushing force and 2268 N pulling force (due to the 25 mm rod area). At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
A rear-cap screw lets you shorten the stroke end by up to 10 mm in the field. Pick the SCJ when you need to fine-tune the stop position after installation or for different setups. Choose a fixed-stroke SC cylinder if your stroke length is permanently fixed and never needs adjustment.
