The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X160-10S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø63mm bore, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X160-10S is a double-acting single-rod pneumatic cylinder with a field-adjustable stroke end, letting you fine-tune the 160mm nominal stroke by up to 10mm via the rear-cap screw. At 0.5 MPa it delivers 1559 N push and 1402 N pull, with a 20mm rod and M16x1.5 knuckle thread, making it suitable for mid-force positioning tasks where commissioning or format changes demand a quick end-stop adjustment.
This model includes a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors can be clamped directly onto the tie-rod barrel for reliable end-of-stroke detection. The 63mm bore body length A(SCJ) is 197mm, with PT1/4 ports and a 28mm air cushion to decelerate the piston smoothly near stroke end.

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 | 1559 N | 1402 N |
| 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 setup, the 10mm adjustment screw lets technicians dial in the exact stroke end position for a pick-and-place arm without swapping out hard stops or reprogramming the controller.
In a welding or assembly jig, the adjustable stroke compensates for electrode wear or part tolerance drift over thousands of cycles, maintaining consistent clamp force by advancing the stroke end.
On a packaging line running different box heights, the SCJ63X160-10S can be quickly adjusted to change the pusher stroke end, reducing changeover time compared to fixed-stroke cylinders.
Choose the SCJ63X160-10S when you need a 63mm bore cylinder with a nominal 160mm stroke and the ability to trim the stroke end by up to 10mm without removing the cylinder. If your force requirement grows, stepping up to an 80mm bore provides 2513 N push at 0.5 MPa; if you can accept a fixed stroke, a standard SC63X160 simplifies the assembly. For replacement, match the bore, 160mm nominal stroke, 10mm adjustment range, PT ports, and the -S magnet option.
At a 160mm stroke, rod deflection is not typically a concern for this 20mm rod under moderate loads, but if the application involves significant side forces, consider adding an external linear guide or switching to a guided cylinder to protect the rod bearing.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, the push force is 1559 N and the pull force is 1402 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 3118 N. The pull force is always lower because the 20mm rod reduces the effective piston area on the return stroke.
Yes, if you need the 10mm stroke-end adjustment feature. The SCJ shares the same mounting footprint and port size (PT1/4) as the SC of the same bore. Ensure your mounting accessory is from the SCJ subset (Basic, FA, LB, or TC) and that you account for the slightly longer body length A(SCJ) of 197mm due to the rear adjusting mechanism.
