The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X160-100S 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, 160mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X160-100S is an 80 mm bore, double-acting single-rod pneumatic cylinder with a nominal 160 mm stroke and a 100 mm rear adjusting screw, giving you a field-adjustable stroke end from 60 mm to 160 mm without changing the cylinder. At 0.5 MPa it delivers 2513 N push and 2268 N pull, and the built-in magnet (S suffix) lets you clamp CMSG/DMSG/EMSG sensors directly onto the tie-rod barrel for reliable end-of-stroke sensing.
This adjustable-stroke design uses a 25 mm diameter piston rod, PT3/8 ports, and an M20x1.5 rod thread, with a 28 mm air cushion at each end for smooth deceleration. The body length A(SCJ) is 239 mm, slightly longer than a fixed-stroke SC of the same bore to accommodate the screw mechanism. It operates on 40 µm 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.

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.
The 100 mm adjustment range lets commissioning engineers dial in the exact stroke end on a new machine without swapping cylinders or machining custom stops, accelerating factory acceptance testing.
On packaging or filling lines that run multiple product sizes, operators can quickly reset the cylinder's end position to match a new format, minimizing downtime between batches.
In pressing or clamping fixtures where tooling wears over time, the rear screw can be advanced to compensate for material loss, maintaining consistent contact force without replacing the cylinder.
Choose the SCJ80X160-100S when you need to fine-tune the stroke end position by up to 100 mm during commissioning or format changes. If you need more force, step up to the 100 mm bore SCJ100 (3927 N push at 0.5 MPa); if you need a smaller footprint, the 63 mm bore SCJ63 offers 1559 N push. For applications that do not require field adjustment, a fixed-stroke SC80X160 is a simpler, lower-cost alternative.
This model is a direct replacement for another AirTAC SCJ80X160-100S with PT ports, basic mounting, and a magnet. At 160 mm stroke, rod bending is not a primary concern, but if the load applies significant side force, pair the cylinder with an external guide rail or switch to a guided cylinder. The rear screw only sets the stroke end position; it does not adjust speed or force.
Adjustable-stroke checklist
At 0.5 MPa, the cylinder delivers 2513 N of push force (full bore area) and 2268 N of pull force (bore area minus the 25 mm rod). At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. Because it is a single-rod cylinder, push force is always greater than pull force.
Yes, the SCJ80 mounts using the same basic, FA, LB, or TC accessories as the SC80, but the body is longer (A=239 mm) to house the adjusting screw. Ensure you match the port thread (PT in this case), magnet option, and that the 100 mm adjustment range covers your stroke variation needs. The SCJ is a tie-rod cylinder, not an ISO 15552 profile cylinder.
