The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X150-10S 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, 150mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X150-10S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, offering a 10 mm fine-tuning range via a rear-cap screw. With an 80 mm bore and 25 mm rod, it delivers 2513 N of push force at 0.5 MPa, making it a strong performer for medium-to-heavy industrial tasks where precise end-position setup is critical.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG/DMSG/EMSG sensors along the tie-rod barrel for reliable end-of-stroke detection. The body length A(SCJ) is 239 mm, and the standard PT3/8 ports ensure straightforward pneumatic integration. The adjustable screw shortens the stroke end by up to 10 mm, ideal for commissioning tweaks or format changeovers.

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.

Fine-tune the end-of-stroke position by up to 10 mm during initial machine setup. The rear adjusting screw allows engineers to dial in the exact stopping point for a gripper or pusher without re-plumbing or replacing the cylinder.
Quickly adapt to different product sizes on a packaging line. The adjustable stroke lets operators shift a stop gate or diverter arm's end position by a few millimeters, reducing downtime between production runs.
The built-in magnet (-S) works with clamp-on reed or solid-state sensors to confirm the piston has reached its adjusted end position. This is perfect for sequencing tasks where a PLC must verify a clamp or ejector has fully extended.
Choose the SCJ80X150-10S when you need robust force and a small, precise stroke-end adjustment without swapping the cylinder. If you require significantly more force, step up to the 100 mm bore (3927 N push at 0.5 MPa); for a lighter, more compact solution, the 63 mm bore provides 1559 N. If your application demands a fixed, non-adjustable stroke, the standard SC80 series is a more economical choice.
For a direct replacement, match an AirTAC SCJ adjustable-stroke cylinder with an 80 mm bore, 150 mm nominal stroke, a 10 mm adjust range (-10), PT ports, basic mounting, and a magnet (-S). At this 150 mm stroke, side-loading is typically minimal, but always ensure the load is guided externally if any radial force is present to prevent premature rod bearing wear.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. The push force is higher because the single rod reduces the effective piston area on the return stroke. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 5026 N.
It can replace an SC80 of the same bore and stroke if you have clearance for the slightly longer body (A=239 mm) and need the 10 mm stroke-end adjustment. The mounting and port dimensions are identical. Ensure you order the same options: in this case, a magnet (-S) and PT ports. The rear screw lets you set the stroke end anywhere from 140 mm to 150 mm.
