The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X60-30S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 30 mm range without swapping the cylinder. Ø80mm bore, 60mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The AirTAC SCJ80X60-30S is a double-acting, single-rod tie-rod cylinder featuring a rear-cap adjusting screw that provides a 30 mm field-adjustable stroke range, letting you fine-tune the end position without swapping the unit. With an 80 mm bore, it delivers a substantial 2513 N of push force at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa, making it a robust choice for medium-to-heavy pneumatic tasks.
This model includes a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The 25 mm piston rod, PT3/8 ports, and a 28 mm air cushion ensure smooth, reliable operation. The body length is 239 mm, and it handles speeds from 30 to 800 mm/s, suitable for dynamic applications requiring frequent stroke adjustments.

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.
Quickly adjust the stroke end by up to 30 mm when a packaging machine switches between box sizes, eliminating the need for mechanical stops and reducing downtime.
Fine-tune the actuator's end position to compensate for tooling wear in pressing or clamping operations, maintaining consistent quality without replacing the cylinder.
Set the precise throw of a diverter arm on a conveyor line. The 30 mm adjustment range allows for easy recalibration when product flow or lane widths change.
Choose the SCJ80X60-30S when you need to dial in a precise stroke end point during commissioning or for different product runs, as the 30 mm adjustment screw offers on-the-fly flexibility. If your application requires more force, stepping up to the 100 mm bore provides 3927 N of push at 0.5 MPa; for a lighter, more compact solution, the 63 mm bore offers 1559 N. For a direct replacement, match the 80 mm bore, 60 mm nominal stroke, 30 mm adjust range, PT3/8 ports, and the -S magnet option. If your task does not require stroke adjustability, the fixed-stroke SC80X60 is a simpler, cost-effective alternative.
Adjustable-stroke checklist
As a single-rod cylinder, push and pull forces differ. At 0.5 MPa, the theoretical push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N.
No. Like all standard pneumatic cylinders, the SCJ80X60-30S will drift or drop if air pressure is lost or the valve is centered. The air cushion only decelerates the piston at the stroke end, and the adjusting screw only sets the end position. To hold a load without live pressure, you must add an external rod lock or a pilot-operated check valve.
