The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X160-75S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 75 mm range without swapping the cylinder. Ø80mm bore, 160mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X160-75S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, offering a 75 mm tuning range via a rear-cap screw. With an 80 mm bore, it delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it a robust actuator for applications where the stroke length needs precise on-machine commissioning or frequent format changes without swapping the cylinder.
This model features a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors, enabling reliable end-of-stroke detection. The 25 mm diameter piston rod and PT3/8 ports ensure solid pneumatic performance, while the 28 mm air cushion at each end decelerates the piston smoothly. The tie-rod construction provides a durable, serviceable design, with a body length A of 239 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.
| 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.
Fine-tune the end-stop position during machine commissioning without needing to re-machine brackets or swap cylinders, saving significant setup time.
Quickly adjust the stroke for different product sizes on a packaging or sorting line, enabling a fast format changeover with a simple screw adjustment.
Take up mechanical wear in a clamping or pressing fixture over time by adjusting the stroke end, maintaining consistent applied position without replacing components.
Select the SCJ80X160-75S when you need a 160 mm nominal stroke that can be shortened by up to 75 mm at the rear end. If the 2513 N push force at 0.5 MPa is insufficient, stepping up to the 100 mm bore (SCJ100) provides 3927 N. For a lighter load, the 63 mm bore (SCJ63) offers 1559 N. If your application requires a fixed, non-adjustable stroke, the standard SC series is a more economical choice. A direct replacement must match the 80 mm bore, 160 mm nominal stroke, 75 mm adjustment range, PT port thread, and the -S magnet option.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, the cylinder provides a push force of 2513 N and a pull force of 2268 N. The maximum push force at the 0.9 MPa operating limit is 4523 N.
A screw on the rear cap sets the mechanical end position of the piston stroke. You can shorten the 160 mm nominal stroke by up to 75 mm in the retract direction, allowing for precise, on-machine tuning of the cylinder's stopping point.
