The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X150-100S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 100 mm range without swapping the cylinder. Ø80mm bore, 150mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X150-100S is an 80 mm bore, double-acting, single-rod pneumatic cylinder with a field-adjustable stroke. A rear-cap screw provides a 100 mm adjustment range, letting you fine-tune the stroke end from 50 mm up to the nominal 150 mm maximum. This model generates 2513 N of push force and 2268 N of pull force at 0.5 MPa, driven by a 25 mm diameter piston rod.
It is a tie-rod cylinder with PT3/8 ports and an M20x1.5 rod thread. The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG/DMSG/EMSG sensors along the barrel for reliable end-of-stroke detection. The body length A is 239 mm, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

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.

Related types: SC (single rod, fixed stroke), SCD (double rod), SCT (multi-position). SCJ mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Dial in the exact stroke end position during machine commissioning without cutting rods or adding hard stops. The 100 mm adjustment range allows rapid fine-tuning for perfect alignment.
Quickly adapt the cylinder's stroke for different product sizes on a packaging or sorting line. The rear screw adjustment makes format changes fast and tool-free.
Take up mechanical play or wear in end-of-arm tooling over time. The adjustable screw lets you restore the precise stopping point without disassembling the actuator.
Choose this 80 mm bore for applications needing around 2513 N of push force at standard plant air. If your force requirement is lower, stepping down to the 63 mm bore (1559 N push at 0.5 MPa) reduces air consumption and physical size. For higher forces, the 100 mm bore provides 3927 N push. The 100 mm adjustment range is ideal for processes with frequent format changes or where the exact stop position must be dialed in during commissioning.
This cylinder is a direct replacement for an existing AirTAC SCJ80X150-100S with a PT port and basic mounting. If your application requires a pivoting movement, select the TC centre trunnion mount instead. For strokes of 150 mm, side-loading is generally manageable, but always ensure the load is guided if significant radial forces are present. If you do not need the stroke-end adjustment, a fixed-stroke SC80X150 cylinder is a more economical alternative.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. The maximum push force at the 0.9 MPa operating limit is 4523 N. The force is identical to a fixed-stroke SC80 cylinder because the adjustable screw only changes the stroke end position, not the piston area.
You can replace a fixed-stroke SC80X150 with this SCJ if you need the adjustable stroke feature and have space for the slightly longer body (239 mm A-length). The port size (PT3/8), rod thread (M20x1.5), and mounting footprints are compatible. Ensure you order the same magnet and mounting options to match your existing setup.
