The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X160-100S 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. Ø63mm bore, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X160-100S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke, delivering 1559 N of push force at 0.5 MPa. Its rear-cap adjusting screw provides up to 100 mm of stroke-end reduction, allowing you to fine-tune the piston's stopping position without swapping the cylinder or adding external hard stops. The 20 mm rod and PT1/4 ports handle demanding industrial cycles, while the 28 mm air cushion decelerates the load smoothly at the end of travel.
Built with a tie-rod construction, this unit includes a built-in magnet (-S suffix), enabling direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors along the barrel for precise position feedback. The standard TPU seal operates reliably from -20 to +70 °C, and the body length A(SCJ) is 197 mm, making it a compact solution for tasks requiring frequent stroke adjustments, such as commissioning new tooling or accommodating part variations on a production line.

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.

| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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.
During machine commissioning, the 100 mm adjustment range lets technicians dial in the precise stroke end for pick-and-place or ejection mechanisms without fabricating custom stops, accelerating the debug process.
On packaging lines that handle multiple box sizes, the adjustable stroke allows operators to quickly reset the pusher cylinder's end position for a new format, minimizing downtime between batches.
In clamping or pressing fixtures, the stroke can be incrementally extended over time to compensate for wear on tooling or seals, maintaining consistent clamping force without replacing the actuator.
Choose the SCJ63 bore when your application requires a push force around 1559 N at 0.5 MPa. If you need a lighter, more compact unit, the 50 mm bore offers 982 N of push force. For higher force demands, stepping up to the 80 mm bore provides 2513 N. This adjustable-stroke model is ideal when the exact stroke length is unknown during design or needs to be changed periodically; if your stroke is fixed, the standard SC series is a more economical choice. For a direct replacement, match the 63 mm bore, 160 mm nominal stroke, 100 mm adjust range, PT port thread, and the integrated magnet sensor option. Since the nominal stroke is 160 mm, side-loading is typically minimal, but for applications with any off-axis force, consider an external guide rod or a guided cylinder to protect the rod bearing from premature wear.
Adjustable-stroke checklist
At an operating pressure of 0.5 MPa, the cylinder produces 1559 N of push force and 1402 N of pull force. The push force is greater because the single-rod design means air pressure acts on the full bore area during extension, but the rod area is subtracted on the retract stroke.
A rear adjusting screw limits the piston's extension stroke end by up to 100 mm, allowing you to reduce the 160 mm nominal stroke to any length between 60 mm and 160 mm. It is a direct replacement for another AirTAC SCJ63 cylinder with a 100 mm adjust range, but if you never need to change the stroke, a fixed-stroke SC63X160 model is a simpler, more cost-effective alternative.
