The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X180-10S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø80mm bore, 180mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X180-10S is a double-acting, single-rod pneumatic cylinder that puts stroke-end fine-tuning directly on the machine. With an 80 mm bore and a 25 mm piston rod, it delivers 2513 N of push force at 0.5 MPa, making it a strong mid-range actuator for pressing, clamping, and positioning tasks. The rear adjusting screw provides a 10 mm field-adjustable range, letting you dial in the exact stroke end without changing the cylinder body.
This model includes a built-in magnet (-S suffix), so CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. The body length A(SCJ) is 239 mm, and the standard air cushion is 28 mm at each end. It uses PT3/8 ports and an M20x1.5 rod thread, operating on filtered air from 0.15 to 1.0 MPa across a -20 to +70 °C temperature range.

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.
| 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.

The 10 mm rear screw lets technicians fine-tune the end position during initial machine setup without swapping cylinders or machining hard stops, speeding up line commissioning.
On packaging or assembly lines running multiple product sizes, operators can quickly adjust the stroke end to accommodate different box heights or part thicknesses.
In pressing or clamping fixtures, the screw can be advanced slightly over time to compensate for tooling or pad wear, maintaining consistent clamp force without reprogramming.
Choose the SCJ80 bore when your application needs roughly 2513 N of push force at standard plant air. If you need more force, stepping up to the 100 mm bore provides 3927 N of push at 0.5 MPa. For lighter, faster cycles, the 63 mm bore offers 1559 N. The adjustable stroke is ideal for commissioning and format changes, but if your stroke is fixed and never needs field adjustment, a standard SC80 fixed-stroke cylinder is a simpler, lower-cost alternative.
For a direct replacement, match an AirTAC SCJ cylinder with an 80 mm bore, 180 mm nominal stroke, a 10 mm adjust range, PT ports, and a built-in magnet. At this 180 mm stroke, rod deflection is minimal under axial loads, but if the application introduces significant side forces, consider adding an external linear guide or switching to a guided cylinder to protect the rod bearings and seal.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N (reduced due to the 25 mm rod area). At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical force at 1.0 MPa is 513 kgf.
A screw in the rear cap mechanically limits how far the piston can retract, shortening the stroke end by up to 10 mm. It is a mechanical stop for adjustment, not a locking device. The cylinder will not hold its position if air pressure is lost; an external rod lock or pilot-operated check valve is required for load holding.
