The AirTAC Airtac AIRTAC SCJ63 Standard Cylinder SCJ63X60-10 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 SCJ63X60-10 is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that provides up to 10 mm of field-adjustable stroke end position. This allows precise fine-tuning during commissioning or format changes without replacing the cylinder. With a 63 mm bore and 20 mm rod, it delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa, making it a robust choice for medium-duty automation tasks.
At 0.9 MPa maximum operating pressure, the push force reaches 2805 N, providing a substantial power reserve for clamping, pressing, or ejecting applications. The cylinder body length A(SCJ) is 197 mm, and it features a 28 mm air cushion to decelerate the piston smoothly at stroke end. The PT1/4 ports and M16x1.5 rod thread ensure straightforward integration with standard pneumatic fittings and linkages.

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.
Fine-tune the retract or extend end position during machine commissioning to compensate for stack-up tolerances in tooling or fixtures.
Adjust the stroke end to take up mechanical play or wear in linkages and pivot points, maintaining consistent part contact without replacing components.
Quickly reset the cylinder stroke for different product sizes on a packaging or assembly line by turning the rear adjusting screw.
Choose the SCJ63X60-10 when you need to dial in a precise stroke end position on the machine, such as setting a hard stop for a material thickness change. If 10 mm of adjustment is insufficient, the SCJ63X60-20 offers a wider 20 mm range. For applications requiring higher force, stepping up to the 80 mm bore provides 2513 N of push force at 0.5 MPa. If the stroke must be fixed and repeatable without any field adjustment, the standard SC63X60 fixed-stroke cylinder is a more economical alternative. A direct replacement must match the 63 mm bore, 60 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N due to the 20 mm single rod. At the maximum operating pressure of 0.9 MPa, the push force increases to 2805 N.
A rear adjusting screw lets you shorten the stroke end by up to 10 mm. Pick the SCJ when you need to fine-tune the end position on the machine without removing the cylinder. Choose a fixed-stroke SC if your application requires a permanent, non-adjustable stroke length.
