The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X130-30S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 30 mm range without swapping the cylinder. Ø63mm bore, 130mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X130-30S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, providing a 30 mm adjustment range via a rear-cap screw. This model delivers a push force of 1559 N at 0.5 MPa and up to 2805 N at 0.9 MPa, making it a robust choice for applications requiring precise end-position tuning without replacing the cylinder.
Equipped with a built-in magnet (-S), it is ready for CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. The 20 mm rod and 28 mm air cushion ensure smooth deceleration, while the PT1/4 port and standard TPU seals suit general industrial environments from -20 to +70 °C.

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 end-stop position during machine commissioning without swapping cylinders or machining external hard stops, saving hours of setup time.
Adjust the stroke end to compensate for tooling or gripper wear over time, maintaining consistent part contact in automated assembly cells.
Quickly adapt the cylinder's end position for different product sizes on packaging or labeling lines, reducing changeover downtime.
Step up to the 80 mm bore if your application demands more than the 1559 N of push force this 63 mm model provides at 0.5 MPa; the SCJ80 series offers 2513 N. For a fixed, non-adjustable stroke, the standard SC63 series is a simpler alternative, but this SCJ unit is ideal when you need to fine-tune the stroke end during commissioning or for format changes. A direct replacement must match the 63 mm bore, 130 mm nominal stroke, 30 mm adjust range, PT port, and the -S magnet option.
At a 130 mm stroke, rod deflection is typically not a concern, but for applications with significant side loading, an external guide or a guided cylinder should be used to protect the rod and seals.
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 the 0.9 MPa operating limit is 2805 N. The adjustable stroke screw does not alter the cylinder's force output.
A screw in the rear cap allows you to shorten the stroke end by up to 30 mm from the nominal 130 mm maximum. It sets a mechanical stop for the piston, enabling precise, tool-free adjustment of the cylinder's extended position.
