The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X130-40 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 40 mm range without swapping the cylinder. Ø63mm bore, 130mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The AirTAC SCJ63X130-40 is a double-acting, single-rod pneumatic cylinder engineered with a rear-cap adjusting screw, providing a 40 mm field-adjustable stroke range. With a 63 mm bore delivering 1559 N of push force at 0.5 MPa (2805 N at 0.9 MPa), this model is ideal for applications requiring fine end-position tuning without cylinder replacement. The 20 mm piston rod and 28 mm air cushion ensure robust, decelerated cycle ends.
This adjustable-stroke design allows operators to dial in the exact stroke end needed during commissioning or format changeovers. The cylinder body length A is 197 mm, and it uses PT1/4 ports. As a genuine AirTAC component, it is built for reliable, repeatable performance in demanding industrial sequences.

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.
Allows engineers to precisely dial in the actuator's end-stop during initial machine setup, accommodating minor build tolerances without needing to swap out the cylinder for a different stroke length.
Ideal for packaging or sorting lines that handle multiple product sizes. The 40 mm adjustment range enables a quick mechanical stroke change to match a new box or container dimension.
In clamping or pressing operations, the adjustable stroke can be used to take up mechanical wear on tooling or contact surfaces over time, maintaining consistent applied position without reprogramming.
Select the SCJ63X130-40 when you need to fine-tune the stroke end by up to 40 mm on a machine. If the 1559 N push force at 0.5 MPa is insufficient, stepping up to an 80 mm bore provides 2513 N of push force. For applications requiring a fixed, non-adjustable stroke, the standard SC63 series is a more economical choice. A direct replacement must match the 63 mm bore, 130 mm nominal stroke, 40 mm adjustment range, and PT port thread.
For this 130 mm stroke, side-loads are a key consideration. Ensure the load is guided externally and the rod is not subjected to direct radial forces. If external guiding is difficult, a guided cylinder assembly is a more robust alternative to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
The output force depends on the operating pressure. At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 2805 N. The push force is higher because the single rod reduces the effective piston area on the pull stroke.
Yes, this is a direct form-and-function replacement for any AirTAC SCJ63 cylinder with a 130 mm nominal stroke and a 40 mm adjustment range. Ensure the port thread (PT) and mounting style match your existing setup. The rear adjusting screw allows you to replicate the exact stroke end position of the previous unit.
