The AirTAC Airtac AIRTAC SCJ63 Standard Cylinder SCJ63X60-10S 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, 60mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X60-10S is a double-acting, single-rod AirTAC cylinder with a field-adjustable stroke end, providing up to 10 mm of fine-tuning via the rear-cap screw. With a 63 mm bore and 20 mm rod, it delivers 1559 N of push force at 0.5 MPa and 2805 N at 0.9 MPa, making it a strong choice for applications needing precise end-stop calibration without swapping the cylinder.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG/DMSG/EMSG sensors on the tie-rod barrel for reliable position feedback. The standard PT1/4 ports and M16x1.5 rod thread ensure straightforward integration, while the 28 mm air cushion decelerates the piston smoothly at 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.

During machine setup, the 10 mm adjusting screw allows engineers to precisely set the final stop position of a 63mm bore actuator without remachining brackets or changing hard stops, speeding up system validation.
In clamping or pressing fixtures, the adjustable stroke can be periodically tweaked to compensate for tooling or pad wear, maintaining consistent clamping force and position over the production lifecycle.
On packaging lines, the SCJ63X60-10S can quickly adapt a pusher or diverter's end position for different product sizes, reducing downtime during format changes compared to a fixed-stroke cylinder.
Choose the SCJ63X60-10S when you need to dial in a stroke end on a machine during commissioning or changeover. If 1559 N of push force at 0.5 MPa is insufficient, stepping up to the 80 mm bore provides 2513 N; if it's excessive, the 50 mm bore offers 982 N. For fixed-stroke applications, a standard SC63X60 is a simpler alternative. A direct replacement must match the 63 mm bore, 60 mm nominal stroke, 10 mm adjustable range, PT ports, basic mounting, and the -S magnet.
For strokes of 60 mm, side-loading is typically not a primary concern, but always ensure the load is guided and aligned with the rod axis to prevent premature seal wear. If the application involves significant off-axis forces, consider an external guide rail.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. The maximum push force at 0.9 MPa operating pressure is 2805 N. The theoretical force at 1.0 MPa is 318 kgf. Pull force is lower because the rod reduces the effective piston area on the return stroke.
The rear cap has an integrated adjusting screw that limits the piston's stroke end. You can shorten the effective stroke by up to 10 mm from the nominal 60 mm maximum. It is a mechanical end-stop adjustment for position, not a speed or force control.
